i found this shop close to home that might be able to bore my im .... but i juss have a question ....

wen boring the im ...does the whole inside need to be bored out or just the opening that connects to the tb(are the passages to the cylinders the same size as the main intake passage)
thanx

 

all of it smile.gif just doing the inlet when you can do more seems a waste

 

Bore out AT LEAST the inlet (where the TB connects) and the runners (where the engine connects). Only gasket-match the runners.
