Ok, I have a completely stock 1993 RX-7 with 36,000 miles on it and I want to do some reliability mods. These are the mods I plan to do (this is the order I plan to do them in):

1) Pettit AST
2) Turbo Timer
3) Downpipe
4) Fluidyne Radiator

Will these modifications work in this order with a stock set up? Could I also throw in a K & N Air filter into the mix? Besides the increased reliability, what kind of HP increase can I expect (if any)?

Thank you!

P.S. - About searching the forums - I have searched and I just wanted some direct input on my specific condition. Thanks again!

 

Thats a good mod list to start out with. All those mods are mostly reliability mods. Adding the k&n filters and cat back will also give you good performance. Thats as far as u want to go without getting a new ecu though.

 

you can easily do these mods and more (cb,pulleys,ic) without the cu upgrade(i dynoed w dp,cb and open stock airbox @ 11 to 1 afr) there is much documentation to support this...go creazy, have fun but make sure everything is done right and one thing at a time
