Where can I port-match intake for B18B throttle body?

I bought a B18B TB a while ago and tried to install it. It didn't work.... The gasket off the d16y8 TB didn't match up right and I had all kinds of vacuum leaks that made the car rev up and down, so I removed it and put the original one back on. Now I want to try again....

I'm gonna guess that if I want this TB to work, I'm gonna need a gasket for the B18B TB, right?

More importantly, where can I go to get my intake port-matched to match up with the larger outlet of the TB? Anyone know approximately how much that would cost?

you could do it yourself. Just trace the shape of the new gasket onto the throttle body and with a carbide bit and die grinder (a dremel tool would probably work ok too) grind it out until you've reached where you've traced.
I HIGHLY recommend doing this with the intake manifold OFF, to avoid any metal shavings going into your engine. Make sure to thoroughly clean the shavings out of the intake manifold before re-installing.
You'd probably pay a little too much IMO to have a shop do this b/c they have to remove the manifold.....but i'm sure pretty much any performance shop could do this for you.
