I have a 87 n/a with an air intake and exhaust. I was wondering if there is an aftermarket intake manifold available for the RX7? Or what other modifications can you do that is relatively easy to do and cost effecive?

I am looking to get a little more power out of the engine...what other recommendations do you have?

Thanks........

 

There's nothing really available that doesn't require fabrication and replacement of the stock EFI system.

For a little info, check out this thread:

Thanks for the reference.

I wonder why they don't offer something.....

 

No demand. Consider that in order to run a custom intake you must also replace the stock EFI system with something tunable, so it's a decently sized investment.
