Is a 65 mm edelbrock throttle body too big for my car, basic bolt ons done, with a set of cams.

if you are looking for a bigger t.b. bore yours and save the 180 to spend elsewhere. i dont think you will see that much of a gain especially with a stock intake. but thats my o.o2 i could be wrong.

don't mean to jack or anything, but do you know how to bore a tb? is it something you can do with a drill press, or bring it in to a machine shop? cost?

for your application better cams, valve springs and retainers, diffently look into a type r intake manifold

well i did drop in a set of cams...a stock throttle body for a b16 is about 58mm. I have upgraded to a 65mm. Is it too big and should i trade for a type r

get a manifold to compliment yout throttle body. like a type r or blox or skunk.

and to bore a t.b. you need a machine like a bridgeport and you need a lathe to put the correct bevel on the throttle blade.

look at http://www.maxbore.com for info on boring throttle bodies.

what about a victor x edelbrock. Or is that too big.

it depends how crazy you want to get, if you want a street car, type r is the best, port the head, cams valve springs retainers, at least 30 hp increase.

65 is pretty big, on my h22 its 62 and that was a "big" tb. however, more air doesnt really turn muc difference unless you are supplying more fuel or have the valve train to support it. you have to work from both ends.
