i used to have a 1983 rx7 gs... i got rid of it because i did not have the money to buy everything i needed for the car... so i screwed around and picked up a running 87 t2. she is stock as stock can get... but i want to start modifying what i can i have 1500 and am wondering if anybody has used the jic bullet twin exhausts? i really would like to try it out or maybe the apexi dual n-1 cuz apexi is the ****... thanx in advance for any help...

 

screw duals, mo weight... go a single exhaust (less expensive too). Intake, bigger secondaries, get an S-AFC, boost controller, FCD. look in the classifieds on here and go to town!

 

I would first spend money on giving the car a full tune up. (Fluids, plugs etc.) Then focus on modifications. As for the exhaust I would look into a racing beat system.

 

Racing Beat makes an awesome dual exhaust. But as for first things first, I'd do a good 60k mile tuneup, just to make sure nothing goes bad during your bigger upgrade. That's always a bad thing to come towards.

 

Modifying a TII can become a slippery slope.

If you upgrade the exhaust past a certain point, you'll need an FCD. At that point you will likely also need to port the wastegate to maintain a sane boost level. Anything above 9-10 PSI needs fuel upgrades which necessitates an upgraded pump, larger injectors and some way to control them.

If you are just looking for a little bit more power, then first complete a full tuneup and make sure the car is working as it should. Then, get a QUALITY exhaust like the Racing Beat system. It won't be cheap, but it's the best available. Port your wastegate. Even just opening up the exhaust without increasing boost will give you a considerable jump in power.

 

+1 for the single. I got APEX N-1 single on mine and love it. Wouldn't change it for anything.

 

Firstly, you need to do a full tune-up. After that, exhaust and FCD is a good way to go.
