Im in the process of finishing my DB8 LS/VTEC turbo build and was wondering if anyone could tell me how much HP I can push for on a stock ITR head???

bottom end, turbo and fuel- GE sleeved B18b, eagle rods, arias pistons(stock bore), T3/T67 H.O., walbro 255, 1000cc injectors, planning to tune 91 octane and q16...still debating on tranny. I have a b16(SC4) and GSR...still researching.


Thanks for any responses..

96 GSR-T

people make 800+ whp on stock port heads, you can rev an ITR head to 8500-9k or so, not much else to mention, you still using the stock IM?. You could probably max out your 67ho but I would never attempt to run over 550whp on a stock valve, just my personal preference, your motor is only as strong as its weakest link..........

I am running a B16 1-4 and a GSR 5th and a 4.40, rips like a **** on the street and strip

There is no more advice. On that head you can go as high as the turbo will let you. That, and your management (incl. injectors) would really be your only limit. The turbo is good to over 650whp, so there's nothing more to advise.
