intake manifold adaptor plate
 

I recently found out there was an adaptor plate made to allow use of a stock 12a carb and manifold on a 13b engine...

IM looking for info on where to buy this part. IT would answer the problem of how to run the 13b I want to put in my 83 GSL to replace the poor 12a. This is a low dollar project...I have plenty of s4 13b parts siitting here, and I dont mind a bit of fabrication either. Just need a way to control the new engine. Right now, its either this, or gut a 2gen for the wiring needed to make the EFI conversion.

Kevin quit being lazy LOL make the damn part you need LOL

Actually doesnt Racing Beat have 13b carb intake manifolds? anyone?

Yes but not for Nikkis...

Yeah true its only for holleys, dells, and webers right?

There is currently an intake manifold from a '76 13B on Ebay. Currently $25.

I lost the link but just search for Mazda manifold and it will come up.

I think this should fit the bill - looks to be Nikki pattern for the carb. 4-port 13Bs are just stretched 12As of the same year.

Saw that one - it's listed as "Racing Beat Header" so I clicked it hoping it was an exhaust header.

Rats.
