I purchased a 92 hatch with the d15b7 and i am going to get a td04 and i was wondering if i could get some instructions on the setup. I heard something about that instead of having a different fuel management unit something about a AFC HAC. the head on it has been ported and polished. its got somewhere around 10.5 compression so i know i will need different pistonsto drop it the compression to low 9s or 8s. but otherwise just wanted some advice. apprecitate it.
