I see.

Thanks for the info bro.

By the way, looking for Skunk2 Air Intake Manifold that is made for 4G93.
Apparently it makes your throttle much lighter and it's plug & play!

I have looked through mudah.my and only to found those with 70mm intake bore.
I'm using mivec TB, which is only 60mm. How does the Skunk2 Air Intake Manifold bore fits my 60mm mivec tb?

to achieve 140whp, u dont really need a mivec piston (from my opinion). stock piston with thinner metal gasket already offer u slightly more compression ratio. then pnp, mivec tb, less restrict intake system, better extractor and hi-cam will definitely increase (with proper tune) your engine's volumetric efficiency. slightly higher CR + better VE = higher Dynamic compression pressure. There's a lot tuner out there who can increase your hp, but not all pro enough to increase it efficiently.

Just bought a skunk2 intake manifold and fixed on my 4G93.
Also fixed ficd for the air-cond idle timing.

However, when the air-cond is on, my idle timing sounds as if i have high cams on.
Where as if i off the air-cond, my idle becomes normal.
And, with or without air-cond on, when i start driving, it turns back to normal.

Is this normal or what?
My mechanic is asking to come back for another visit to check on the air/fuel flow and is concerned that my fuel might not be sufficient on the high rpm section.

Anyone has installed a skunk2 intake manifold on a 4G93?
The rpm is much lighter and responsive now though but i'm shifing at 5k rpm now, to be safe before future investigate. Hehehe

wait, did u get the skunk2 intake which is made for 4g93?from what i know there is no skunk2 for 4g93, there are only for b16, b18 but u can mod the intake flange to fit the 4g9x engine.

and yes, if u use mivec tb the size is 60mm, while the intake is 70mm, its ok, but u wont unleash the full potential of the skunk2 intake. but i think it is sufficient for ur current engine setup.

Actually there is a replica skunk2 made for 4G93, almost plug & play but there's a few misplacement for the screws on the fuel rail which can also be customized. My mechanic did a great job for the little misplacement and it was good to go.

However, when I'm idling with air-cond, my air/fuel ratio is 19.9 =.="
But when I'm throttling, it goes to 13, which is alright. Idling is a bit off, that's all.

Croydon, shit man that's 1 little monster there. On top of that, Millennium Motorsports' dyno is pretty heavy right! Yet you could pull out that HP! Awesome shit :wavey:
How much is the mivec head by the way? hehehe

cheers!

Hello all, I'm currently using a GSR Turbo with TD05H E3 turbo. Using E-Manage blue for tuning and running at 1.1 boost. I'm using E3 fuel injectors 510cc. Blitz boost controller.

I thougt of upgrading to higher topspeed. Curently I'm getting 210kh/h @ 7,000 rpm on stock GSR gear box. What's all the sifu's advice on this? Should I go for E3 gearbox? Or E1..E2 gearbox? Or just chg final gear ratio and add LSD?

What's the recommended boost? If I boost 1.5 bar, should I change the...
