Hmmm.. well.. yes headers. Lightened flywheels, a supercharger kit that works well, looks nice, and fits properly, rx-7 headlight conversion, intake kits (looks like the integra intake will work for that one?), forged pistons/rods, underdrive pulleys, cams, stainless steel valves (try calling REV, Racing Engine Valves @ 800-398-6348), fuel rails, high rpm valve springs, polyurethane bushing kit, high perf distributor, gear ratio kit, turbo kit, ---- those are a few things that I can think of that are either non-existant, or hard to find for the first gen/3.0
headers? I think someone mentioned headers once or twice, headers? hahahaha, yeah headers?
That's true about the radiator, I had mine replaced once and I asked for an all metal one and he said he would be able to find one, needless to say, he couldnt and we had to go with one from Performance Radiator. It's painted black and has a metal top, so I don't know how much different it is than the original one.
Maybe a thicker radiator would be good too as these engines seem to run pretty hot... and anything to cool it down would be in our best interest..
