how can i use a 4 port turbo 13b block with my dellort. what lower intak manifold will bolt up to my racingbeat upper intake? can i use the 70's 4 port 13b 4 port manifold?

i would think so.

Im using the stock 6prt Lower mani with the RB upper mani.

I think the upper mani is the same for the 6 or 4 prt.

Good luck.

The RB upper manifold should bolt up to a GSLSE lower manifold -OR- the RB lower manifold. The old 4 port manifold will not work because it has a 4 bolt pattern for a carb where the GSLSE bolted to an upper manifold. I think RB still has the lower manifolds.

i have a dellorty carb.
i have a corisponding racing beat upper intake manifold.
i need it to bolt to a lower manifold that bolts up to a 4 (4) port 13b. (as in, turbo II block)

i dont think im understanding you correctly, or you're not understanding me.

Here are the gaskets for the old school 13b and the turbo II 13b. The mounting holes do not line up.

Here are the gaskets for the Upper to Lower manifold joints. Look more promising to me.

yeah.....but the gsl-se is a 6 port.
the turbo II is a 4 port.

Dude.......

You have the RB Dellorto carb.
You have the RB upper manifold.
The upper manifold will mount to a GSL-SE Stock lower manifold.
The GSL-SE stock lower manifold will not bolt up to the turbo motor. Look at 1st picture post
The GSL-SE mid gasket looks close to the mid gasket for the turbo mid gasket. Look at 2nd post.

If it were me I would go to the mazda dealer. Ask to see a 86-88 Turbo II upper to lower manifold gasket. Hold it up the the RB upper manifold and see if it matches. The you know all you need is a turbo II lower manifold to put it on your engine. Sometimes it take actually doing it to find out the answer.
