so the h22 is on its way.im going from auto to manual and i want to get plenty of performance parts before the install that will be easy or free of charge because the engine will already be out.so far i purchased:cat-back exhaust,high flow cat,skunk 2 obd conversion harness,underdrive crank pulley,fidanza short shift adapter,and a weapon r secret cold air intake.i have headers from my 96 f22.will they fit?what other mods can i do while the engine is out that wont cost me labor?i will post pics when the swap is done.
