Or farking sorry ... I didn't know it was so small. Other than the size dimensions, TB upgrades is still pointless. I don't see why it needs to stop at 70mm, might as well go all out and get it up to 100mm and see what happens. :roll:

you will notice a difference in throttle response but this is all relative to what mods you have done. i experienced alot of loss in low-down power, but gain heaps in the top end! this is on a b18c! going too big is not wise because your engine cannot produce enough vacuum to move the air!
one more chance : how much is ur one bored out?? any dyno results?
hey there...Quote:

cheers
I had mine bored to 63mm, there was a nice boost in throttle response but I doubt there was any HP increase
one more chance : cool, sounds good... i'll definetly look into this... after i get my I/H/E done :).
cheers.
