Is there a difference between 1991+ intake manifold and 1990?

I have a 90 TB and intake manifold (and a lot of other '90 parts) on my VR4. I am switching the TB out for a '91 and want to know if there will be any issues attaching the '91TB to the '90IM. I only ask because I know that the 90/91 TBs are different.

Thanks in advance

It will bolt on without issue.

 

Great, thanks!

All 1g intake manifolds are the same, 90 has a different throttle body with a different tps plug. 90 fuel rail is different from a 91-94 fuel rail also.

sorry for hijack but does that mean the 91 galant N/A intake manifold is also the same as the VR4 one?

A N/A intake will be the same except it will be missing one vac. port. More specifically, the line that the bov line usually attaches to. But, that can always be t'd off of another port.

considering the # of mani's out there I'd find one with the BOV port, you'll wish it was there at some point.
