20B or 13B-REW owners help me out
Hey guys I really need a Throttle body inlet pipe. I would rather buy the factory one instead of fabricating one. If anyone could help me out that would be great.
Thanks,

Despite appearing the same. There is actually a slight difference in the bore diameters of the two throttle bodies.
Naturally, the 20B being the larger of the two.
I think from memory, the primary ports are the same size & its the secondaries that are larger for the 20B version

With the tb's I have heard conflicting reports on which is bigger (20b vs 13bre) or better for the 20b. Would someone that has both just mic them already and let us know for sure?

Well, I'm not going to use that much of it at all. Just the part that connects to the TB till it tapers down to about 2.5" should only be using about 6" of it. It would cost me more to make one than to jsut buy one and cut out what I need.
