What RB upper manifold to use with a s4 tii lower intake manifold?
Anyone know the anwser to this one? I have a RB mani on my 45 DCOE but it does not mate up to the S4 Tii lower i just bought. Anyone know the part number to what i need? Anyone atually have a similar setup?

This is sort of strange... the Carb should sit on the LIM already and it should be a racing beat LIM like this one here:

In which case you would not need any more LIM's. That manifold bolts directly to the engine. Do you have a picture of your setup? From what you described I am a little confused.

Oh crap i should have specified more. I have a Weber 45 Dcoe ( sidedraft) carb with a racing beat upper manifold trying to connect to a tii lower intake manifold ( so i can put the turob in without a spacer).
The problem is the bolt spacing is bigger on my upper than my lower.
Here is my carb and upper.

i would think you need the r.b. lowwer na intake and then get a 6port na to a 4 port adapter plate so it would be like this...block(4 port), 4 port block(adapter plate)6port manifold. r.b. 6 port lowwer man., r.b. webber upper man. carb. and i dont think a 45 dcoe will feed a t2 motor to well id get a holly

There is a difference between the 74-85 & 86-92 manifolds ( http://www.mazdatrix.com/r-weber.htm )
Are you rtying to mate a 74-85 manifold to a S4 LIM?

Well the issue was that i was trying to put a 86-92 manifold on a 85 and older lower intake manifold. SO thanks to DVCN (local RX7 guy) i got ahold of the correct manifold.
Once i got it home i compared it to the s4 tii lower intake mani i have. There are some differences. First off all 5 bolt holes will have to be machined for it to fit.
Just figured there would be some people interested in this.
