i was wondering how to make my 86 na faster, it handles great due to kyb agx shocks and eibach prokit and i already have a straight pipe header apexi n-1 duals and an intake, i was just wondering if anyone has done any mods and which were good and what not.

 

The only two things that 'we' have found that are really worth the $ on a n/a is 1) a FULL DUAL exhaust like the one Racing beat makes and 2) an aluminum flywheel. Yes you can actually make some more power with a well tuned carbeurator, however for a street car I don't think you want to go there...

 

Actually after those mods I would suggest porting the manifold. All of the flanges between the intakes L,M,U need to be expanded as well as installing some 6p racing sleeves. This combined with the TB mod should yield around 15-20 hp. Thats what both mazdaspeed7 say and Agent D. Also if your running really rich u can get lots of power with a s-afc.

 

You would be better searching the second gen forum for this info. In fact I'll get you a thread to start out with.
Big thread, lots of things you can do to get every last bit of power from your car.

thank you all for your help

 

You guys are getting dull, no one made the classic comment, "sell it and buy a turbo II."

 

hey come on now, the car just showed up in my driveway one day from my brother, and i put a new motor and **** in, so ive kinda grown attached to it, you probaly all know how it feels in one way or another........

 

Even though I have just done that I can't say it cuz I had dreams with my NA I told my GF I would never sell it, but look how quick it goes once you boost

 

My NA dreams went quickly also.....Right around a telephone pole at about 45mph. So....I looked for a TII as a replacement....

My NA stopped working and then I came across some $$$ and out popped a TII
