I did a search!!
My next setup im going for 550 wheel horse and was wondering with my setup, do u think it could be done with basically a stock GSR head?
IM planning on doing valve springs and cams that alow me to rev to about 9500RPM. but i dont want to invest in actual head work.Im doing it to almost prove a point but saving the cash is also a factor.Ive seen it done a bunch of times, but i just want to get some opinions, and maybe some examples of HP gains when porting is applied.

Also, is a simple catch can enough ventalation for this much power? I see alot of people tapping 2 fittings into thier valve covers and was wondering if this is nesscary, or can I just stick w. my old catch can system.

The setup
Fully built LS/vtec with 9-1 CR and 84mm bore.Stock LS crank and main caps.
GT35R .82A/R
Full Race Style Ramhorn mani with wastegate in front
A big backdoor IC
Hondata
and all the other essentials.


I know its a vague question but gimme some help guys.Thanks

 

shouldnt be a problem, just gona take alot of boost

 

Thats one of my concerns.Ill do what ever it takes to reach that mark though.
What cams could i use to get a good long power band w/ this big of turbo.
Its going to be a street/track car so I want to have a broad power band instead of peak power

 

Stock sleeves, stock head with springs and retainers...no port work:

 

Damn that anwser's alot of questions

 

Jeff Evans can make it happen

 

what cams should i run?

 

stock gsr with some kinda aftermarket valvesprings and retainers

 

stock GSR cams wont let me use the full potential of this trubo.I want this thing to rev high but still retain a broad power range.

 

wrong, people make hella power with gsr cams.

and with your 500whp goal, you wont have any problem

 

a set of ITR cams will work really well also.....

i bet with itr cams and gears you can gain an easy 50whp, or get the same horsepower with less boost

 

Just remember that many things can be accomplished with stock parts. The real question is "for how long will it live?"

 

When I was on stock head, St00pid made 680 Whp with 520 Ft/lb on a T3 (GT3767S). All we have was springs and retainers. Granted we were in the upward of 40 psi ish, but we made it there...
