I got a little bonus at work today and now I'm already thinking ahead to the next race. I'm planning on finishing out the rest of the 30hp for $500 plan. We already did the a4 header, race muffler, and the prelude ecu. Next would be the a6 cam, the a6 computer, the h23 intake, and the black box. I'll probably also replace the cat with a straight pipe and plumb in an improved intake.
I was thinking about taking the stock intake pipe and air box from the same prelude si that I get the IM from. The air box is bigger so the bigger filter will flow better. I figure if I relocate the battery to the passenger compartment there will be room for the bigger air box. I've already replaced the right headlight with a scoop for my cold air / ram inlet so I can plum that into the new air box.
I'm also figuring that instead of just buying a cam from an f22a6, I'll take the whole head. That way I get the stiffer stock springs. We rev this baby and i don't want the more aggressive cam floating the valves at speed.
So since I'll be swapping out the head anyway, I am wondering if someone sold a good but extra thin head gasket to bump up the compression a little bit. Does anyone know the thickness of the stock gasket? I found the Bismoto thin gasket and I'm considering that possibility. If I know the stock thickness I could calculate the improvement in the compression ratio to see if it is worth the $119 for the gasket. Are there other alternatives out there?
