12a turbo question

Hey guys been awhile since ive been on here. the v8 swap never happend cause i got the 12a running. But now i want a lil more power im heavily favoring turbo but i need some help. Ive already searched and couldnt find what i needed so ill ask. Is the 13b and 12a exhaust manifold the same bolt pattern or does anyone make a turbo manifold for the 12a ? If i overlooked where this has been answered before point me there please. thanx for any help

Yeah it's been covered. The 13B manifold would need to be modified to fit a 12A. There are some guys on here that make custom 12A Turbo headers. Welcome back. I'm happy to the see the V8 swap fell thru. Post pictures of the 7

that's good a ****'ed on doesent belong in an rx7 anyway..no the 13b and 12a exhaust mani's are not interchangeable, and would have to be modified to fit..even then, your going to have to modify the intake mani and possibly the carb to fit. pm 680rwhp12a he would know everything you need to know about turboing your 12a. and maybe he can hook you up with some stuff to do so as well.

THATS MY INTAKE SET UP!!!

Thanks for posting that, thats the first time I've seen another 40IDF set up identical to mine. Except I only have the Weber and manifold, none of the turbo components.

The must have made a 13b and 12a model

Here's mine, evidence that it will fit a 12a, not quite as shiny...
