Some Upgrades

Ohayo Gozaimashta!
Just a quick update on this blog. I just changed my camshaft to higher and wilder specification. I decided to go for 300in/288ex from 272in/272ex from Matspeed. Other than that, i also swapped my current ecu to j5 ecu from Matspeed. All i can say that, i really love the response at high rpm! all the way up to 9000 rpm! orgasm! Some pix below

cam installed!

Set the camshaft timing using the dial gauge for proper cam setting.

proper tools

degree wheel

And after finish with the setup, we then checked the air fuel ratio with innovate wideband sensor and did some tuning from the air fuel ratio reading.

more to come. stay tuned!

JUN camshaft for 4g93

Hi guys.

Nowadays, there's a lot of after-market camshaft that we can choose for 4g93 such as Matspeed , Powerzone , Kelford Camtech and RPW. And I'm quite shock to see that JUN also produce high performance camshaft for this engine. At first I thought JUN only produce camshaft for 4g92 MIVEC. Hmm , I think it is weird. I didn't see any link at JUN website about this product. Since I'm quite skeptical with the product and wanna know whether the camshaft is originally produce by JUN or is it just made in Chow-kit road, I made an effort to write to JUN Auto Mechanic Company , and soon after that they replied me back. Here's the email.

So , I think for those who wanna buy this type of camshaft to upgrade it, don't worry since they already stated that they DO produce 4g93 high performance camshaft especially for Malaysia market. A good news isn't it?




This are the specs that JUN produce :

• For 4g93 Turbo : 272 degree , 10.8mm lift on intake and exhaust
• For 4g93 NA : 272 , 288 , 304 and 11mm lift on intake and exhaust

The choice is your.

Now i really feel like wanna upgrade from matspeed to JUN high-cam but the question now is,

money where are thou ?

regards.

Camshaft Upgrade

This is the the best modification so far. A set of a new regrinded camshaft. The company which regrind the camshaft is Matspeed. It's very well known in Malaysia. Matspeed can custom all the the specs of camshaft that suit you. They have variety of duration for 4g93 which are 264, 272, 288, 292 and if I'm not mistaken they also have 300 degree of duration cam.

Since i wanna tune my car both for daily use and super hero during weekends track day/ saturday nite, =p ,so i've made up my mind to go for 272 degree on the intake and 272 degree on the exhaust. Wow... this is the spec for me! Really satisfied with the power increments!

The sound that it makes imitate the boxer engine. You get the idea =)
