Yes, actually it's funny that yesterday I was with my friend tuning a Vortech Supercharged G35. he had water injection installed, he told me to touch the intake pipe then the plenum then the whole manifold.. and it's funny that after few runs.. the intake pipe was warm... the plenum I think where the methanol is coming in is ice cold and the manifold is cold...but I wasn't talking about safety for the car....I'm a little confused.. that VAFC barely increases fuel, it's actually good in trimming, so it barely fixes the AFR..what about the timing.. you didn't touch timing.. !!?!?! and you have 375 WHP ?!

I'm going to tell my friend for sure... he's a tuner..and I'm sure he's going to go crazy when he hears that... 175 WHP added with no ECU mod...

 

^^^ Yes I'm sure he will shake his head in disapproval lol But that's fine, I've been running a this system about 3 years and 50k miles now. I know what the strengths and weaknesses are....probably better then anyone, becuase no one else has the balls to run it lol

The VAFC is used purely for fine tuning/shaping my fuel curve by trimming fuel where I want and lower vtec point, it will not successfully add injector duty cycle without freaking the ecu out so it is not in place for adding fuel. I rely on the water meth- typically 75% meth) for detonation suppressant so I do not need to reduce timing at my boost level with the Centrifugal ....and it also is a fuel, so it supplements the added fuel my Comptech rising rate fuel pressure regulator and stock injectors do not support on their own.

 

I have experience with the greddy kit and if you want fast spool that t518z is at full spool at like 4k. If you want that power you should look into the pfab kit. Its cheap and I think it looks sexy. My .02

 

I've got a few local turbo guys in the club and just my impression being a non turbo guy, but the GT30 size turbo seems to be about the best overall fit for the S in spool/response and broad enough power with enough kick up top to make a real dent 300trq/425whp+

 

im an all motor kinda guy, tried boosting my gsr hatch, back in the day but cancelled due to lack of funds for "propper" tuning and accessories...but out of curiosity...are turbo kits for S2000's a/c compatable?

 

yes, they are a/c compatible, if you get a "proper" kit (not a piece of junk). it's usually a good idea to get the a/c relocation lines, too, though.

Just make sure you keep it cool so it doesn't over heat and kaboom. Drifting puts a lot a lot of stress on a car
