Do all 7 (?) bolt/stud holes line up the same for any 13B from '84 - '91?

Port runners don't matter so much as do bolt holes.

Let's say I have an S4 or S5 TII LIM, and wanted to use it on my recently acquired GSLSE. Would it BOLT up? Or, if I wanted to go with just an S4 or S5 NA LIM?

I'm still trying to decide which route to go... turbo or stay NA. This BNR stg. 1 is staring me in the eye on my shelf as I type this up though...

 

As far as bolt pattern goes yes it will physically bolt up. You already know that all of the work will be in port matching.

 

If you have a turbo intake manifold and want to put it on na block you have to drill/tap your center iron iirc.

Hmm, so of the 7 holes, just the one with the bolt going through to the center iron does NOT match?

 

the hole doesn't exist period, heres a pic of a na 6 port - turbo 6 port swap

I love pictures, thanks!

 

Why tap it? Just don't use it. The other manifolds are fine without it.

Don't ask me, i found this off a diff thread and thought it would be of help.
