well the time has come to step to the next level and im going to take out my safc and put a standalone on the 7. my questions is how much whp can a TII make with bolt-ons only. RB turbo back exhaust,walbro fuel pump, turbosmart bc, bigger secondary injectors, spalm e-fan, koyo rad, turbosmart bov and a fpr, that's all i think the 7 has. im aiming for 300whp for now, i don't know what whp im going to make but if i don't make 300whp( i think it will not hit 300whp lol maybe 270- 280 or something) then im going to upgrade my front turbo housing to a t4 so it can reach the 300whp. just want to know if anyone had go the same route as im going just to know what to expect when i tune the car.

thanks

How big of secondaries?
720s will be pretty close to maxed out if not maxed out at 300
1000s will provide enough for about 350 rwhp
These tend to be fairly conservative numbers, but rather safe than sorry.

i took out my 720's and im ordering soon some 1000cc, i had that in mind also, but don't you think 1000cc is too much for stock turbo???? im going t4 but first im goona see what i can do with the stock turbo.

I usually just use this http://rx7.com/cgi-local/2ndgencalc.cgi

From what I've seen it does a pretty good job.
Fuel usage is determined by power made and efficiency, not just the size of the turbo, though that has some play in efficiency.
