has anyone bored out there throttle body and actual have got any hp and tq gains
i read about how people have 62, 63, 64 mm bore, is it worth it?

 

A big throttle body is one of those things you need to go when everything else is being upgraded. Say with a stock head, stock intake manifold, no others mods with a real flow increase, the throttle body won't help really at all, because of the other bottlenecks. There is always the possibility you could gain power though, but you could also possibly lose some, i'd say unless you're really flowing a lot more than stock, spend the money elsewhere, like a good header.

 

i am using a j's copy intake, an AEBS intake mani, and soon to have a CTR intake cam all on a B16. my TB is stock right now at 60mm, i have been leaning towards boring it to 64mm, good idea? thanks.
