1G Intake Manifold Differences

[laser92awd]

I bought an extrude honed intake manifold from RRE. After (finally) removing mine from my car, I have noticed differences. (See picture below).

Basically, the bolts are cast on opposite sides, and the extruded manifold is missing a port - there is not even a hole in the casting.

What should I do?

Very interesting.

Seems one is from a Turbo and one from a Non-Turbo?

My 1g turbo manifold looks like your dirty one. Studs for TB ase closer to Fire wall and I have the other vaccuum port, of course.

yes what he said.. one is non turbo and one is turbo manifold. i have a non turbo manifold on my car.. all i had to do was tap it for another source for the BOV.. didnt have to as I coulda used something else but figured I might as well..

and in regards to the 2 bolts on the TB, they unscrew out and you can move em to whichever side they need to be on
