is it possible to gain 90whp with mostly bolt on's (obviously w/o turbo bc im in the all motor forum) bc i dont want to have to do to much internal work, atleast not more then is required at this time


*and my engine is a b21a1, hard to work with, but i like a challenge

 

no

 

it might be possible.... some people claim a DOHC Sticker adds 25 Horsepower, but I have yet to see actual dynos on that.

 

id consider ITB's a bolt on, if tuned right you could prob get close to 90 HP

uhhh
no

 

90 at the crank, that sound better?

 

with just itb umm.......... still no

 

maybe itbs w/ a 125 shot direct port

 

ITB's are not even worth it for some applications. Lets think about it this way, can you gain 90whp from going all motor in a GSR factory motor. It puts down in the area of 150whp so to see that motor produce 240whp, I think you can but not just bolting **** up. You are goin to have to overbore, aggressive cams, tune, and tune some more.

actually what you're gonna have to do is ditch that shitty *** motor.
B21A = ***
Maybe on a GsR, or possibly even a B16, but I'd doubt a B16 that had never been opened (maybe with cams or something) would make 90 whp over stock.
