CPR FD Turbo Manifold

I have been working with CPR to develop the ultimate FD rx7 exhaust manifold. CPRs design has been a proven manifold to make big power on the FD two rotor 13BREW engine. The manifold is paired with a tail V60 wastegate.

The manifold:

The first down pipe will be developed for the Garrett GT40-900 turbo. The down pipe list will include the GT40-1150, BW SX-E and others to follow. If you are looking for 600+ HP this is the manifold that will get you there.

Moving on to make the first Down Pipe for the CPR manifold. So far so good. Once it is all packed up the engine will be put back in the chassis to double check the fit and clearances. If all good it's down hill from here on the first turbo set up anyway.

The main down pipe is tacked and ready for test fitting, once the testing is completed in the chassis the dump tube will be able to be finished up.

Test fit successful! I am happy with how it turned out so far. Now just to tie the dump tube back into the down pipe. It was difficult to get a picture of the ground clearance but the downpipe is not lower than the sub frame so that is a win for me.
