Throttle Body Port Polish

[auggiereg]

I just bought a throttle body from a 95 Civic Si for my Dx and I wanted to know where and how much it would cost to get it port and polished. Southern California locations are preferred. More precisely anywhere near West Covina would be even better. Thanks for the info.

you should just put a 60mm b series throttle body on it... more cost effective.

Easy cheap and effective. Any OBD1 B series would work well.

I already bought the thing and has been shipped to me. If I were to port and polish it would I also need to port and polish match the intake manifold? The throttle body is already at 62mm would it be pointless to port and polish it?

From my site, Re-measure it on the side that goes to the Manifold it's only 56mm stock, I'm sure it wasn't bored out to 62; however if it is, it's already ported and yes you wil need to port match the manifold. It's easy to do yourself. Put the TB on the IM and mark it with a marker, then dremel it out.
