You can advance the timing a little to you get the results you want. Usually good for about 3 or so horsepowers. Also you could tighten the screw on the vaf but I dont recomnend this if you dont know what your doing.

Erm...too many threads, you need to read up on this, ClubProtege.com has lots of good info...

Anyway, B code VAF from 2nd gen RX-7, I got mine for free(2 of them) but I bought a different one(a P code from a Capri Turbo) for $15. People have gotten 8+ WHP from that alone.
Cone filter...might be able to piece together an exhaust pretty cheaply...
