Does anyone know if there are other cast turbo manifolds out there that have the same shape and mounting as the Bell Tuning log exhaust manifold? I have a down pipe from them and wanted to buy the right exhaust manifold that would allow everything to line up correctly.

Very few manufacturers make manifolds with exactly the same positions.

Both because it's difficult to make it all line up the same, and because they want you to buy their down pipe too (so why make something to help your competition)

You really only have 3 options:

1: Buy a new manifold from Begi
2: Find a secondhand Begi manifold
3: sell the Begi DP and just buy a new matching set of manifold and downpipe.


Personally i'd just go with option 3.
A downpipe is much easier to have custom made if needed than a manifold.

The FM manifolds put the turbo in the same approximate location as the old BEGI manifolds (because originally FM was selling BEGI parts). I have no idea if recent BEGI manifolds are the same as that or not, though.

I agree with selling the existing DP and building a new system. If it is the same as the current FM location, it's actually not a great location because of clearance to the "shelf". People are putting much bigger turbos on Miatas today than they were 25 years ago.

The current fm manifold "should" fit. I think this question was asked in the past, search around fm manifold and begi dp. You can always try and ask begi/fm.

It should fit. Years ago I had a flyin miata log manifold with a bell dp pipe and it fit fine. I currently have a begi log manifold on my t25 with flyin miata outlet and 3inch downpipe. It rubs slightly onto the transmission but I haven't actually made time to readjust it.

Maybe it was just my luck, but I'm running a tacotaco manifold on my NA and everything fit up to a begi dp without issue. YMMV.
