Silicone Radiator Hoses.

Holla.
Another 'small' update to my ride. Pix below =)

tadaa!

New silicone hoses for my radiator since the old one which is rubber leaks. I recommend this upgrade for those who are in need of replacement since silicone has many advantages over rubber. There is a good chance these will be the last hoses your car will ever need hopefully. You will also be surprised by how soft your stock hoses have become with age.

Highlights of B16B 98 Spec R compared to B16A

Hi guys!

I would like to share some useful info about the king of NA engine!



Highlights behind the high-RPM, high-output of the B16B 98 SpecR.

In order to increase the power output by 15 hp, and the max RPM by 200RPM, the engine goes through many upgrades. It should be noted that the B18C spec.R's cylinder block is used for its endurance.

The translations for the numbered labels in the diagram are:

1. Cylinder Head - Complete port & polish
2. Exhaust Valve Spring - High-lift, dual-layered spring
3. Sparkplug - High-heat-type #7 platinum plug
4. Pistons - High-compression, low-friction, custom pistons
5. Connecting Rod - High-output, high-durability, lightened, custom conrod
6. Engine Stiffener - Aluminum die-cast, high-durability, one-piece type
7. Crankshaft - Full-balancer, 8-weight, high-output, custom crankshaft
8. Inlet Valves - Lightened inlet valves
9. Inlet Valve Springs - High-lift, flat-surfaced, dual-layered spring
10. Camshaft - Wide-angled, high-lift, high-durability camshaft
11. Intake Manifold - High-RPM type.

The camshaft profiles (wild cam) change from B16A 160ps to 170ps and finally to B16B are

Cam Profile: B16A 160ps Max Lift (IN/EX): 10.4/9.4

Open Timing (IN/EX): BTDC 10/BBDC 40

Close Timing (IN/EX): ABDC 40/ATDC 5

Cam Profile: B16A 170ps Max Lift (IN/EX): 10.7/9.4

Open Timing (IN/EX): BTDC 15/BBDC 40

Close Timing (IN/EX): ABDC 45/ATDC 7

Cam Profile: B16B 98R Max Lift (IN/EX): 11.5/10.5

Open Timing (IN/EX): BTDC 18/BBDC 45

Close Timing (IN/EX): BTDC 45/ATDC 10

Different pistons are responsible for the compression ratio increases between 160ps & 170ps B16A and the 10.8 ratio for B16B. Readily apparent is the relatively modest change in piston top between B16A 160ps and B16A 170ps for the 10.2 to 10.4 change. However, the radically different piston top for B16B is very clear from the picture. The increase in compression ratio between B16B from B16A is 0.4.

The cut-outs on the piston top to accomodate for valve lift are basically the same between all three piston. This could meant that B16B camshafts can be installed into both 160ps and 170ps B16A without the need to change to B16B pistons.



On B16B, the inlet ports are manually ported to increase air-flow. The exhaust ports are identical to B16A



B16B intake valve seats are at a different angle to B16A, 45 degrees vs 60 degrees. The intake valves are also different, being lighter and having a thinner valve stem.



On the left are the power curves for B16A 170ps versus B16B. Note the big gain in power after 6000rpm, the VTEC switch-over point between mild and wild cam profiles. The gain at extreme high rpms is readily apparent on the curves.

Various individual specifications for B16B can teach us about the feasibility of various modifications to B16A. For eg, the throttle bore diameter for B16B is identical to B16A at 60mm. This means that enlarged throttle bodies for B16A might not be an optimal mod or that a compromise in power delivery might result, eg loss of low-end power in return for gain in high-end power. Note that B16B has identical low and mid range power as B16A.

As with B18C Spec R, the wonder of B16B is the assurance of a 15 to 25ps gain in power on a B16A provided the tuning done by Honda can be completely replicated. Nevertheless even if only a portion can be duplicated, combining with properly designed aftermarket exhaust, headers, and intake could still potentially realize this 15ps gain.

Proton's Crash Test Vid

Hi guys.

Just a quick update. Got this video from the net. It is about Proton's crash test.

The Right Balance.

Hi guys.

In this post i would like to share with you some article that i found when i surfing the net. Btw, this article is taken from CBT newspaper , 29th June. This article is about suspension tuning by Tengku Djan Ley and written by Dinesh Appavu. A must read article!

Click for Better View

Btw for those who doesn't know who is Tengku Djan, he is the head of Proton Motorsports (R3) and he is also a Malaysian professional drifter who has taken part in the D1 Grand Prix racing series and others. He has won the 12 hour Merdeka Millennium Endurance race twice in 2005 and 2006. In Malaysia he's called the 'Prince of drift'.

My 'Race Machine'

Hi guys!

As promised! In this post i would like to share with you my other ' race machine ' =p. Picture below.

My Mini 4WD

Actually i already kept this machine aka mini 4WD in my store room for about 7-8 years. I can still remember anime that aired during our childhood which is Dash Yankuro. Still remember? During that time i was one of the kid who really addicted to the anime and really wanted to become the 'next mini 4WD racer'. LOL.

I can still remember last time. What i want to achieve is to have the fastest engine from others. I can say that I've spent a lot during that time but i don't regret that =) What the most important this is i can learn about engine , handling , DIY and whatsoever.

Nowadays, I can see that this mini 4WD is very different in design. Not like last time. The body is wider and the design is a bit peculiar. Haha. Maybe, that's just me. After doing some research on it and consult one of my brother's friend , which is very pioneer with this mini 4WD machine said that today's race is not just about horsepower. It's all about handling. What's the point of having a fast machine but in the middle, the machine jump off from the circuit.

By the way, according to my brother's friend, my machine can classified as 'super car' in today's race since the power generated from the motor is high and from the design of the body. But he also said that if i want to compete in today's race, i have to buy a new shell since today's rules & regulation don't approve this kind of shell. Don't know why. Hmmm. Maybe i'll try to consult other mini 4WD racers to confirm this matter.

A Message

Hi guys.

Not much update on my car. Other than that, I'm quite busy nowadays, so i didn't really have the time to write anything. LOL. Btw, I just wanna express how happy i am to see 4g93 modification scene in my country is keep on progressing. One of the reason why must be because of the performance parts for 4g93 now is easier to get. Not like before. Most of the performance parts only available for mivec and b-series engines. Now, we can choose which one that we prefer. Either to get an imported branded ones or maybe just local made performance parts. The most important things are we buy something within our budget and the parts are worth it to buy. Don't go for cheap product but in the end, you will suffer more loss. I hope you guys know what i mean.

Currently my mechanic is still working on his new project which is 4g93 with ITBs. All the best with the project. If I have some of free time to see the progress in the workshop, i will post some of the pictures to this blog.

Oh, before i forget, in the next post (possibly) i will post my project in reviving my old racing machine. Stay tuned!

I'm akatsuki, and i approved this message.

TRD Clutch & Flywheel For The 4AGE

Hi guys.

Since the current TRD 3 pucks clutch worn out, finally my brother made up his mind to take another set of TRD clutch for his beloved 4AGE engine. But for this time, he chose the full-face organic TRD race clutch and not the 3 pucks design. Pictures below.







He made the decision to choose the full-face design because he founds that the 3 pucks design tends to wear out really fast. A 'no no' for a guy who uses the car as a daily driven car and during weekend track days. Other than that, he also upgraded the stock blacktop flywheel to lightweight ones made by TRD . Picture below.



After the upgrade, i can say the clutch are grippy like the previous 3 pucks design and it wont judder when take off from standstill. The engine also revving 'happily' , thanks to the lightweight flywheel.

The Return of The Hachiroku

Hi guys.

The President of Toyota has revealed the car that will replace the legendary RWD AE86 Corolla or as we all know as 'Hachiroku'. It is due to go on sale towards the end of 2011. The concept car will make its world debut at the Tokyo Motor Show later this month. For the time being, let's enjoy the pictures of the successor below.












Since it's still a “concept,” Toyota hasn’t revealed much about the FT-86 yet, but from reliable source, it will be powered by a Subaru-derived 2.0-liter boxer four sending power to the rear wheels. Toyota focused on keeping the weight down to improve handling and, according to one source, the platform is unique to the concept.

New Project : Cylinder Head

Hi guys.

My hands are itchy to mod again my engine. So today i asked my mechanic to find me another 4g93 cylinder head to do 'Port & Polish'. Last time my current cylinder head is already ported and polished to Stage 1 Port & Polish. But this time, i decided to go for maximum port & polish cylinder head job which most people call it Stage 3 Port & Polish. Other than just porting and polishing the intake and exhaust holes, in this stage, we will also touch some of the other part such as valve seat etc.

But anyway I hope that it is not too late to wish all of my moslem friends Happy Eid ul-Fitr.



Regards & Salam Eid ul-Fitr.

Need For Speed : Shift

I've always been a fan of Need For Speed since i was a kid. On 15 of September 2009, Electronic Arts released the new version of the game which is called Need For Speed: Shift in North America. The game will be sold worldwide on 17 of September 2009. The new version has added a new mode to make battles among friends all the more interesting and to settle “which car is better” disputes. The new mode in hand is the Car Battle mode that pits some of the fastest, fittest, downright nastiest machinery out there in head to head battles. So far fifteen different matchups are possible with cars like the Ford GT going against the Dodge Viper, Cayman against the M3, as well as such exotics as the Murcielago and Aston Martin DBRS GT cars. The point of the game is to pit stock standard, unmodified cars against each other to find out which car and which driver is the best. In the meanwhile you can check out the teaser video below.

This is so olskool!

How To Make 4g93 Perform Like B18c

Hi guys.

When i surfed on the net like usual, i found a very good article but i don't know who wrote this. I think the article is very informative for a 4g93 engine enthusiast like me =p. The writer share some of the recipes on how to make 4g93 engine perform like B18c engine from Honda. Kudos to the writer. So enough with my blabbering. Just read the article below!

In any engine, the only way to make more power is More Air and More Fuel. The easy part is getting the fuel. You simply use larger injectors, work the injectors harder (not recommended) or increase the number of injectors. The tricky part is to get the air in. To do this you either use some sort of device to compress the air and literally ram it through the inlet ports ala turbo charging/supercharging or you can try and increase the breathing performance and efficiency.
Now to increase the breathing efficiency you can do one of those things or all which is what most people normally do. This includes:

1. Increasing the port shape and size so that more air flows in without losing the velocity. As you know Bernoulli's Principle states that if you increase the area you lose the velocity but there are "tricks" which can be employed to juggle between both.

2. You increase the cam duration and lift. The longer the valves are opened and lifted the more the air can flow in. Unfortunately this area is again a compromise. A naturally aspirated engine that has big cam duration and lifts still needs the vacuum in the engine to draw the air in.

And as stated earlier, having the ports open sooner and more valve lift is the equivalent to increasing the air and you lose the velocity. The engine then struggles to breathe at low revs and occasionally loses one of its power strokes due to this efficiency. This phenomenon is called eight stroking and leads to that V8 like idle and poor low-end performance. It also leads to an over rich condition and generally leads to lots of bad exhaust emissions. This problem is not an issue once there's an increase in revs and the efficiency of the engine is enough to match the camshaft characteristics.

So some bloke in Honda must have though "Heck, why can't I have the BEST of both worlds. I have a cam lobe profile that gives an excellent idle and good exhaust emission at low revs plus another cam lobe profile that will give me good breathing efficiency at high revs. Also, let's include an intermediate profile for excellent air swirl to further increase the airflow into the engine. While we're at it let's design a rocker mechanism that is operated using oil pressure via a solenoid to switch between the low and high cam profiles at a preset rpm. Let's control all this via the ECU.

This is what VTEC is. But remember, 1 & 2 are still interlinked. So Honda juggled between the best of both areas and came up with the very first B series engines 10 years ago.

B18c VTEC engine. Haha. Wish i can plonk this engine to my car!

Now let's go back to 2. First. There are many ways to open and close the cams and most road engines usually use a mechanism called a hydraulic lifter or followers. The advantage of this mechanism is it's quiet and doesn't need frequent and labour intensive adjustment like a solid lifter engine. Unfortunately there is a downside to the hydraulic lifter. They don't like long duration and lift.


Hydraulic lifters can suffer from three main maladies: -
i) Pumping up, where the lifter solidifies too early during the lift ramp of the cam and over-lifts the valve, this can happen when an engine is over-revved. But you can control this with a reasonable rev limit.

ii) Pumping-out where oil is evacuated from the lifter causing the lifter to solidify too late in the lifting ramp and the valve is under-lifted mainly caused by too fast a lift or too wide a duration.

iii) Oil aeration which allows the hydraulic lifter to be compressed rather than solidifying on lift, this is the main cause of valve train rattle.

Of these i) is the most dangerous since it can lead to valve/piston contact, ii) and iii) just cause the engine to rattle and subject the lifter/follower and cam to shock loads which should have been absorbed by the take up ramp designed into the cam profile. All in all hydraulic lifters and aggressive cam profiles are not too a happy combination.
Needless to say Honda VTECS don't use this but the 4G93P does

So now that we know, what else makes the B series or the B18C such a good engine? These are:
1. Good port shapes and flow of the engine. The B18C straight out of the box flows an amazing 141+ cfm with no loss when the throttle body and inlet manifold are fitted compared to the 4G93 at around 120+cfm.

2. VTEC enables you to use wild cam profiles. Honda merely specified more lift and duration for the Type R spec. A stock 4G93 has about 256 degrees duration vs. 280+ for VTECS. The B18C is also capable of 11.5mm inlet valve lift and 10.5mm exhaust valve lift, which is simply amazing. The 4G93 is quite good for a hydraulic lifter but pathetic compared to a B18C at around 8+mm of lift.

3. When you use big cam profiles you usually lose dynamic compression (when the engine is working). Now as you know compression is yet another power tool. General theory states that for every 1 point increase in compression you'll get about 3-4% more power. Reason is the valves are open for such a long length of time and generally overlap a lot too (both inlet and exhaust are opened at the same time) that you lose compression. So to resolve this, Honda specified what a very high static compression of 11.1 for the B18C. The 4G93 is only around 10.5 but closer to 10.0

By now you can clearly see that in stock form as far as power output and capabilities are concerned the B18C has all the right "parts" compared to a more road oriented engine like the 4G93P. However all is not lost. You can make the 4G93P perform like a B18C by:

1. Having more static compression

2. Increase cam duration and lift. But you must be asking what about the fact that hydraulic valvetrain hates big cam profiles. There are of course tricks to get around such a thing for which it'll take me even more time than what I have to explain. Maybe part 2? The idle will be poor and lumpy though due to the event I explain earlier.
Emissions? What emissions? Most petrol heads I know of can live with that. Oh and don't forget to increase the revs too.

3. Port the engine in such a way that the 4G93 flows as well as a B18C. This is not an issue so long as you have a Serdi, good skills, knowledge and experience and a flow bench to measure your work.

LOL. A very long article but worth reading right? Btw below is one of the example of 4g93 'fully modified' engine.

4g93 1800cc Engine built by John Bettie producing 218hp. Intake is designed by Jenvey.

Actually there's a lot more of 4g93 fully loaded engine picture that i have but i think i need to ask for their permission to post it on my blog , LOL. Btw, thanks for reading.

Engine and Transmission oil change.

Hi guys.

Normally i change my transmission fluid after hmmm, can't recall. Haha. Btw after watched this video, now i realize that it is important too other than just changing engine oil.

Btw here's the video.

If you use your car for daily basis and not for hard driving, don't bother to change the transmission oil frequently. It is just waste of money ( in a way ). Only for crazy maniac guy who enjoy revving the engine like no one else business are advise to change it when servicing the car =p .. Opsss. am i talking about me?

4g93 with ITBs

Hi guys.

Last week, my friend and me went to his panel workshop to do wide-band tuning to his engine. When i was waiting for the tuning to finish, i took a look around on the other rides in the workshop but then i spotted a mysterious induction sound at the back of the workshop. Im very curious to know where the sound came from so i went to the back and check on the ride. It came from a 'not so flashy' yellow Proton Satria with 4g93 engine. Then i realized, it is the engine that i spotted couple of months ago when it is still in the building up process. Hell yeah. Now, it's finished! Pictures of the engine bay bellow.






I'm craving for this induction setup. The sound from the ITBs is damn sweet. I have to keep this engine specifications as secrets since i've made a promise with the owner =p

p/s: happy fasting to all of my moslem friends.

Open Pod Air Filter Comparison

Hi guys!

In today's post, i would like to share some comparison done by Revspeed magazine Japan. Nowadays a lot petrolheads change their stock airbox to open pod air filter. But the question is that which one is the best in flowing as much air as possible, without sacrificing filtration efficiency. The article compares for most popular kits available which are HKS, Apexi, Blitz and K&N.

Important Notes regarding the comparison:

1. Extracts of this article have been transcribed from a Japanese article featured in Revspeed Magazine, August 1999.
2. The original test was based upon the results found when using filters specifically made to fit the Toyota Supra. However, the filtration is unlikely to differ, as all the filtration materials used are the same for every model of car.
3. The cost given for the filters are based on a the kit for an R33 Skyline GTR, except the K & N kit which only currently exists for a Skyline GTS, and are inclusive of VAT.

Click pix for better view

From the comparison, we can see that Apexi Power Intake wins the test in both filtration and power gains. But for me it is still questionable since the HKS are proven to sell more in the market if compare with others induction kit. I think the battle is futile. So the question still stands, "Which Induction Kit is the best?". You can accept the result from the test then the Apexi Power Intake is the winner but if you are still skeptical don't worry as the performance gains are quite the same =)

Tyre For Dummies

Konniciwa.

Since I'm the mood of hunting new tyres for my ride , so i did a lil bit of research on tyres and i found a very good infos that i think should share with you guys.

How to read a tyre sidewall

Tyre code, commonly molded onto the sidewall of the tyre, is described by an alphanumerical value. This code specifies the dimensions of the tyre, and some of its key limitations, such as load bearing ability, and maximum speed.



Speed Capability

The speed capability of the replacement tyres must always equal or exceed the original equipment tyres. When replacing tyres, refer to the vehicle owner’s manual for correct size.

When the tyre size contains a speed symbol, for example P205/60HR15 or P205/60R15 90H, the replacement tyre must have the same or higher speed rating symbol if the speed capability of the vehicle is to be maintained. If the replacement tyre is not speed rated, the speed capability of the vehicle is limited by the speed capability of the replacement tyre.
Speed Category
S 180 km/h (112 mph)
T 190 km/h (118 mph)
U 200 km/h (124 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y 300 km/h (186 mph)

How to take care of your tyres

Consumers have the primary responsibility for the regular care and maintenance of their tyres. Tyres should be inspected at least once per month. The regular inspection should focus on proper inflation pressure; tread wear and tyre/wheel damage as detailed below. Having tread depth above the legal limit does not determine the service life of a tyre. Tyres must be properly maintained and routinely inspected for continued safe and proper use — even when tread depth remains. Tyres may need to be taken out of service even when tread depth above the legal limit remains. Regular inspection becomes particularly important the longer a tyre remains in use.

This monthly inspection should be supplemented by periodic rotation, balancing and alignment services. Inspection should occur whether or not the vehicle is equipped with a tyre pressure monitoring system.

Tyre rotation

It is important to check your tyres and wheels for signs of possible damage, and check your vehicle for any mechanical problems and correct if necessary. If you notice irregular or uneven tread wear, the tyres should be rotated to alleviate the problem.

You should follow the rotation pattern or procedure indicated in your limited warranty and the vehicle owner’s manual. We recommend you rotate tyres on front wheel drive vehicles and/or all season tyres on any vehicle every 12,000 km to equalize the rate of wear; however, rotate your tyres earlier if signs of irregular or uneven tyre wear arise, and have the vehicle checked by a qualified technician to determine the cause of the wear condition. The first rotation is the most important.

Besides monthly inspection of their tyres’ visual condition, consumers must also be aware of any change in dynamic performance such as increased air loss, noise or vibration. These conditions could be caused by internal damage to the tyre and may require that the tyre be removed from service immediately to prevent a tyre disablement. Consumers are recommended to consult a tyre service professional if any dynamic performance issues are noted.

Driving habits

You may not realize it, but the way you drive can have a lot to do with how long your tyres will last and how well they perform. As you head down the road, there are a number of things to keep in mind.

Avoid hard cornering, rapid accelerations and abrupt braking as they put a lot of stress on your tyres. Smooth, safe driving is not only better for your tyres, but more importantly for you as a driver too.

Watch out for overloading. Driving on an overloaded tyre is hazardous. When your car is carrying too much weight, it can create excessive heat inside your tyres—and that can cause sudden tyre failure.

Never exceed the maximum load rating of your tyres, which you can find on the sidewall of the tyre, or in the owner’s vehicle manual. When you replace a tyre, make sure the new one has a load-carrying capacity equal to or greater than the tyres that originally came with your vehicle.

New Shoes

Hi guys.

There's not much update on my ride except changing the worn out parts such as clutch pump and speed sensor. Other than that, i changed my old and heavy rim to something which are more appropriate to my liking and my car concept ; 15" Volk Racing CE28. Picture below:

Really like the rim design eventhough not as beautiful like my previous 16" rim. Btw, this rim is lighter than the previous one. It will give me an advantage during sprint/drag and also better fuel consumption =p What i need now is to change the tires to better tires. Maybe advan neova? toyo proxes? or just parada spec2 =).

stay tuned.

My Big Bro's Ride

Hi guys.

In today's post i would like to write about my brother's car. It is Toyota Corolla AE101. Pictures below.






Powered by 4AGE 1.6L 20 valves 4-throttle engine design by Toyota and Yamaha. This engine is well known for its ability on track and also touge. This engine in stock form can scream up to 8000 Rpm. The sound it makes during high rev is totally sweeeeeeet! This is the 5th generation 4AGE engine produced from 1995 to 1998 is the final version of the 4AGE engine and has black cam covers. This engine is fondly known as the "black top", and yet again features an even higher compression ratio (11:1), the air flow sensor is replaced with a MAP sensor, the diameter of the four individual throttle bodies was increased from 42 mm to 45 mm, the exhaust port diameter was increased, the intake cam lift was increased from 7.9 mm to 8.2 mm and the intake ports were significantly improved in shape, contour and also the width at opening at the head was increased. This revision increased the power to 165 PS (163 hp/121 kW) at 7800 rpm with 162 N·m (119 ft·lbf) at 5200 rpm of torque. Usually we can find this engine in Corolla Levin / Trueno , Sprinter Marino and Carina GT.

The Engine

Some modifications to the engine are:

• + Custom 4 Throttle Trumpets
• + Ultra Plug Cables
• + DENSO Iridium Plugs
• + Adjustable fuel regulator
• + Fujitsubo Giken 4-2-1 Header (Coated)
• + Apexi N1 muffler (JASMA Approved)
• + 2.3 inch stainless steel piping + Fujitsubo Giken bullet
• + TRD 3 Pucks Racing Clutch
• + Cold Air Intake

Btw, he already planned to upgrade his engine to the next level when he finds the right time to do it =) and i know the time will come ! Toda Spec 4AGE!
