I have a 90 si hatch with a 1st gen b16 swap. I wanna tune it up but what car should I buy the parts for cap,rotor,plugs etc. I have'nt tuned this thing up and it could use it. Should I buy 90-93 or 94-00 gsr parts? 99 SI?? Which car should I buy this stuff for? The Si was only a sohc motor at 108hp I don't buy parts for that motor right?
