Anybody know anything about the cx racing turbo manifold? I'm in need of a new mani and figured I should just upgrade while I'm at it. This is the only mani I can find that looks like it keeps the turbo in the stock location. Here's a link to it. Client Validation

 

You link sucks.(does not work)

Also is your turbo a T4 based turbo?
S4 and S5 turbos both have separate unique flanges,and require their specific manifolds.They can't be swapped onto a different manifold.

 

Weird. Link worked for me. It's an s4 turbo. Here's a different link. cxracing.com: 86-92 Mazda RX7 RX-7 FC Turbo Manifold T4 13B 50mm WG

 

YOU NEED:
A T4 turbo,whatever size and price
.
A External Wastegate(minimum a 38mm),maybe a flange to adapt to that manifold.

A downpipe so you can connect that stuff to your Exhaust.

A Boost controller.

Fuel Injectors as your engine will now suck more fuel.It will need it,as the new turbo is now Shovelling air into a small crammed space!,compared to tossing an air particle into it(like the old stock HT-18s did)

An aftermarket ECU as your stock ECU is now a book end and is not capable of handling any extra "Hi HP" that all this stuff is going to create.

So,is this your kind of "upgrade"?..you decide.

 

I'll probably just stick to getting a stock manifold to replace my current one. I'm not trying to spend a whole lot right now.

 

I have used that type of manifold before and they are good, You can allways weld a plate to t4 manifold plate to match your turbo ,have done before with good results

 

I have that manifold running a Chinese to4e. The hardest part about the swap for me was getting the downpipe made (a good friend helped a lot with that)
ALSO! The waste gate flange does not clear the convertible crosa member and requires further modification if you have a vert.

 

You could BUT, it still won't be in the stock location and will require downpipe work.

 

What she said.

 

RE-RX7...Hence the term..Air Bag.


OP:
You still didnt say what turbo you had.
The S4 or the s5..
they need THEIR Mating manifold. (S4 Turbo needs an S4TII manifold..etc.)
So,Look for the one that you need as they can;t be interchanged.

 

Whats wrong with your manifold?
