Since you guys are all talking about engine swaps, I guess this would be the best place to ask...I have a 94 civic ex with D15B. I read that engine swap 101, and it said to swap a b16a2 into a 5th gen civic all you need is hasport shift linkage, SIR II, and wire in v-tech.. I dont know what SIR II is . Can somebody please tell me what it is and what is everything that I need to to do the swap...
