anyone have a link where I can get these, the local machine shop wants 400 to do the job(youch), but I think they are including matching the intake manifold (porting it) to the new T.B....

anyways, I saw while ago on the group buys about a 125 dollar overbore job....

anyone still have any way to get these? Im planning on running a turbo so cam gears and a larger T.B. allong with ported heads and stuff can only hlep the turbo when I get it....

yeah i got one from that deal, but i dont know if they do it anymore...sorry. but that is a pretty good deal for matching the intake manifold, youd get alot more horsepower from getting that done. I only got like MAYBE 10 horses out of mine, so im gonna get EXTRUDE HONING done to the manifold and plenum to match the bore diameter of 63.5mm

The KA throttle body is already very large, boring it out will only give you minimal gains, mainly in response. Spend that money elsewhere.

Try gude performance, I believe they have bored out throttle bodies. Also extude honing is good on a match ported head. I had it done to my built head. Can send you pics if you like

gude performance will do it but you have to send them your core. The also will do the head, but I dunno if they'll do the plenum.
