I am putting together a new motor for my REPU using S5 TII plates and currently my biggest issue is how will I attach my Weber DCO carb? I have been running a 6-port with stock S4 N/A lower intake manifold with the upper adaptor (similar to Racing Beat but I think its another brand). I dont have a TII lower intake manifold to try it on, so I must ask if the Weber carb adaptor will fit to that? If not, what are my other manifold options? I would rather not have to build something myself, but if thats the only way...

 

Try Jay-Tech. They make/made all kinds manifolds for turbo 13b's.

 

I found Mazdatrix sells a lower 4-port manifold that should bolt to my upper, I will give that a shot.

 

Seems the manifold is for the old school 13b, which is nowhere near the same as a turboII motor. So I may end up having to build my own manifold.

 

Racing Beat has one for the IDA. Not real familiar with the Webers but it might be jumping off point?

 

Thanks, I saw that. IDA is a down draft and my DCO is side draft. My only hope there would be to get some flanges and build a manifold adaptor. Its starting to look like I will either have to build something myself or switch to a downdraft carb.

 

Why not just modify the n/a lower to fit the TII ports? It's easy.

That looks easy enough, I may do that and take the time to clean up the extra crap on it as well.
thanks!

 

I have a Turbo II custom engine adapter, and a Racing Beat lower intake manifold sitting on my shelf I would like to get rid of.

Thanks
