SC-SUZUKA

I purchased another S2000, this one is a 2004 with the beautiful 2.2l, I love this engine. I just purchased a Comptech SC and want my car to hit 400rwhp. I will be purchasing a EMS, 650cc injectors, headers and exhaust with test pipe. What size pulley do I need to run 11psi? I think that at 11psi, I will hit 400rwhp with the set up I will be purchasing. Tell me what you guys think and what should me steps be to hit the goal I want.

Sorry to rain down on the parade but your not going to hit nearly 400hp with just 11psi. A couple vortech guys run 11psi and its ~350-380hp if that. Skip was just saying in a previous thread he was boosting 20psi comptech and at 395hp.

So that is where I'll be at? at 350-380 rwhp range. Anyone else running 11psi and have similar mods?

anything is possible, just depends on how much $$$ you want to spend.

you will also get less boost with an AP2, hence the lower redline. engine work is defiantly a must for 400whp. port and polishing and few other things not to mention u need bout 15psi

I'm purchasing also a F20C head and will port and polish it. I only want to push this engine to 11psi, so what my setup will give me than I'll have to live with it. DSGS2k3, do you have pictures of you force induction with the NOS?

At 10.5psi I put down 375 with headwork and stock exhaust. From what I've researched, I think you'll need at least 13-14psi to put down 400.

John Z, who did your head work? what other mods you you have?

3.25 ASP will get you probably 11 or so, but AP2, maybe not, running a 3.5 to get me 10 psi. Good luck with 400 whp...like the others said above me-15 at least to get lucky.
