i have a 86 rx7 gsx. its n/a. i was wondering right now with stock how fast i could top it out at, what my quarter mile would be, and 0-60 time. just guess if u dont know.

also with max mods how much hp could i get out of it (with and without nos), top speed, 0-60 times, and quarter mile time? im just curious and it would be nice to know.

is there a site that i can look car specs up on? is there any chip on my rx7 that i can replace to get more hp?

 

There isn't a GSX model 2Gen RX-7. It's probably a GXL.

Most people opt for an EMS over a chip nowadays, but here are some chip links if that's what you really want:

which gives more hp? where can i find an ems?

 

A well-tuned EMS will yield better performance, especially in the S4 RX-7's which have slow computers and restrictive airflow meters. However, an EMS is very complicated, and anybody who does not fully understand how to tune an engine should have it professionally tuned. The installation isn't quite as difficult, and shouldn't be a problem for those who are very good at stereo installations.

We have an ECU forum section on this site if you want to learn more.
