60+mm throttle body

what kind of gains will one of these give me? I have been holding off on replacing my tb because I am not sure if it will be a benefit to the car. if a tb will gain a fair bit of power I will buy one. I am shooting for 175bhp

So far I have an open element cold air induction, 2.25in cat back exhaust, 2.25in sport cat and head pipe. I want to get there without opening the engine. Is this even possible?

Might be a bit of a tall order. 175 without head work may be a bit difficult.

its probably an unreachable goal but I'm going to try. I may even add a 4 branch mani to free things up a bit.

you would need the 60mm TB (in the usa they have a cable throttle and can buy bored-out TB's), a 4-2-1 manifold and a bit of luck to reach 175bhp without cams, 170 is probably the max without opening the engine dunno..

170bhp is just fine. Ive had people tell me I wouldn't see more than 150bhp so 170 will be good enough
BTW I can get as large as a 62mm throttle body.
