Hey welcome to the board. Nice to see you got another RX-7, but the 260Zs weren't too bad either. Anyways, there's not much to do to the stock FI system, but you can gain a lot from a whole exhaust system. This topic is very popular so you can find a lot from using the search function located on the upper right. Depending on smog requirements (or lack thereof) you can also port the motor slightly, although 6-ports don't gain much from porting. A possible solution would be to use 12A 4-port end housings. IIRC anyways.

Anyways, good luck in your quest for power, and don't forget to search. This forum has a wealth of knowledge, you just have to know where to look.

2nd gen dynamic chamber for starters

 

2nd gen TB will help too.

 

Welcome!! SE's though they only had 35 more hp are suprisingly quicker then their 12a counterpart. A full exhaust, intake, elec. fan, removed smogpump, clean those intake manifolds, and remove those 6port sleeves(contraversial) should get ya started.

You must keep the 4 silinoid valves and rats nest for the BAC valve to function properly.
