so i have 1986 na rx7. and i wanted to try to get some more horsepower so i started looking at chips for. fact is that i dont know anything about this kinda stuff. any help? what types of brands are good or where can i go to look for them. or if u know just a good chip just tell me. thanks for any help

 

Welcome to the Club.

Performance chips are not available for our cars. You can get an Rtek and tune the car using a wideband O2 sensor to improve fuel economy and increase horsepower some, but there is no 'drop in' chip that will help.

Good Luck!

 

there is no Real perormance chip for an N/A.
Look into ECU's such as an RTEK,or equivalent.
you can always do the basic Bolt on/Add on stuff like exhaust,cone filter etc.
The Ecu however is a little more Complex,and you can't just throw Bigger injectors on and expect the car to run faster and better.the N/a runs ruch as hell already.
Look up a Thread called "BEEFY N/A" . that has lots of info on Modifying an N/A.
Edit.dammit Jack,.,.beat me by ONE minute!

 

If it's performance chips you want, then I would look here:

This statement is mostly true. There once was a time when they made chip upgrades for S4 N-326 ECUs. They do not make them anymore.

I had one installed in my old 86. The process involved sending in your ECU. They would install the "performance chip" and mail it back to you. the upgrade adjusted the timing maps and leaned out the top end. The changes were designed for a stock car with stock exhaust and intake...

By itself, the upgrade was worthless, maybe 3-4 more HP over stock. However the better timing combined with a S-AFC, headers, and intake, the combination was good for about 170 RWHP.

Anyway, the point is that they did make them, but now they dont.

 

 

Since you're new, you might not know this, so I'll tell you just in case...

Beware of ebay and other "chips" which are essentially a 10 cent resistor that you wire in to you ECU or else. Worthless **** that just alters what your engine thinks is the intake temp. (usually), and makes the engine send more fuel in. The NA's already run on the rich side. There is at least one thread in here on this, somewhere.
