Port And Poilish Throtle Body

[2Much_Eclipse]

I HEARD PORT AND POLISHING YOUR THROTLE BODY HELPS ACCELERATION. SO WHAT SHOULD I EXACTLY TELL THE SHOP. ANY SIZE (mm). I HAVE 99 RS WITH CAI AND HEADERS TO MUFFLER.

How much are they charging you to do that? i heard its expensive to get it bored out. i think there 52mm stock. i think they can only bore it to like 54mm or something like that but dont hold me to it. but you might want to check out the jeep throttle bodies, they bolt up to our mani's with a little work, and they are 60mm. i checked the price at the jeep dealer, and it was $270. but i dunno if thats cheaper then the shop you might want to look at that.

i got a buddy that port and polishes heads for a living. Hes actually selling ported 420a throttle bodies on ebay. I got my head done by him and my tb. You cant go anybigger than 51.67 mm around the plate unless you have a bigger plate. He tapers the tb out to 55mm and knife edges it to 60mm and then matches the tb to the plennum. He only charges 70 bucks. matching the tb to the plennum and getting rid of that hump is the biggest gain. I can give you his email address to anybody thats interested. he has good prices on head porting to alot cheaper and same quality as anyshop you can go to.
