4G93 Modifications

[syimirmazlan]

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!

mivec head around rm2k, 4G93 DOHC head around rm1k, many 4G92 SOHC, 4G93 SOHC, waja 4G18 can use 4G93 DOHC head to convert from SOHC to DOHC...

[NoobCity]

i had improvements on the low-end rpm. haven't really felt any power loss yet.

high duration cam, fast spec 272, or 288, a pair of adj cam pulley, high comp piston (mivec is sufficient), skunk2 intake (modified the flange) or gsr intake with larger throttle body (60mm), engine management system, powerzone/rpw/hotbits extractor...and aftermarket drop in air filter ( dont need for open pod)..with these i think u will have a very powerful 4g93, or if u can source a complete mivec head, it will be better...the power is a lil bit less than stock 4g93 turbo if tuned well...
