What are my choices for exhaust manifolds to turbo an 1st generation 13B?

Is there anything out besides custom made stuff?

How 'bout the intake side? Looking to convert to FI and turbo so I'm shopping my options.

I searched and haven't found anything so I figured I'd ask the pros.


Thanks in advance,

Ive got a custom on a 13B in my FB, but im sure most of the FD manifold would fit with very little modification. There seems to be the same room if not more in the FB. As far as the intercooler and piping youll probably end up piecing together something, every picture ive seen are different, which is nice because its truly one of a kind.

Forgot this, the wastegate position will most likely be your biggest challlenge because of the steering linkage but not impossible.

most turbo manifolds made for second generatuon rx7's will fit the first gen, third gen manifolds will not fit.................

Whoops, meant to write FC which is what mine came off of. Its only 1:30 AM here time to go to bed.

I guess I should clarify....

Its a 1st gen engine in a sandrail. The problem isn't with room, its with port configuration...

I need an exhaust manifold to fit an old 4 port and a Fuel Injected Intake that can fit an old 4 port.

Is there anything available that isn't a total custom fab?

Im using the cheap *** OBX TO4 manifold on my FB

its designed for a FD and its on a FC engine.

I had to have a new turbo flange welded on at a new angle, along with some other welding.

but for 175 manifold+ 30 new laser cut flange + 100 in Tig welding it fits like a champ. Turbo and wastegate fitment is perfect.

****, sorry

If you plan on running the stock radiator placement all the FC manifolds place the turbo too far forward. You'd only have 3-4" from the inlet of the turbo and the radiator core. This is the reason I made my own manifold
