Can anyone with an NB intake manifold post a picture of the mating surface for me? I have a 1.8 coldside kit for an na and I want to see the differences between the manifolds. Basically I'm looking to see if there is a way I could make an adapter/spacer to work with the manifold incase I can't find one for the NB head. I do have access to NC mills, so making it isn't a problem. Thanks for the help.

After some emails with Tom at Fast Forward Superchargers, I found out that the bolt pattern is the same and the ports don't line up. How much they're off, I'm not sure. The car is getting put away in two weeks, so once the plates are off of it I'll probably take the intake manifold off and see how far off they'd be. If I get that done anytime soon I'll update this thread with measurements for reference.
