I have a 1973 Rx3 I need help to find a Turbo Manifold.
I am installing a 13b Cosmo turbo engine and need help finding a manifold that will fit to my application.
Any suggestions???..

 

Still looking for help ?

 

BUMP..good luck in your search.

 

HOW ABOUT SOMETHING LIKE THIS

12a & 13b turbo manifolds suit Rx3, Rx4, Rx7 Series 6 Tuned length | eBay

Mazda rotary 13b turbo exhaust manifold | eBay

Exhaust manifold rotary mazda RX3 13B GT42 turbo EM034 | eBay

 

^ that last link is SDR motorsport EXHAUST MANIFOLD which are quite good, but their manifolds will be to accomodate RHD vehicles and can be quite a high and forward mount. I would hazard a guess that something closer to a FC manifold would come close to working? You didnt say what turbo you are using. Really best bet would be custom, but it might be an idea to see if a stock TII manifold and turbo fits for a reference point.
