EX, so it's a V-tech. umm, short throw shifter? The super charger gives better low end torque. Adjustable timing gears? If yyou gotta friend w/a dyno, shell out for 91 oct. gass and advance the timing 2 degrees at atime to see if you get gains. Anything over 5 becomes flirtatious with detonation.Big Bore throttle body?high performance muffler (adds upto 18 psi of power)consider a improved intake manifoldan R-type racing cam (assuming you have the stock SOHC)porting the cylinder headHave you given thought to a swap?You can get a B16A, B17A, B18A , B18B, B18C, B18C5 incl. Type R, H22A1 or H23A1 and F22 engines to fit in there. These all are larger. stronger DOHC engines that make your car able to get into the low 11s to high 10s
