Im about to put an Ls/VTEC into my 1990 civic hatch. Im not to worried about much because he has alot of Honda mechanical experience. That and he did a CRV/VTEC swap in his 90 hatch too so he knows about all the conversions and stuff i will need. I need to get an ECU though. We were planning on getting a GSR ecu, but this is where my question is. Im pretty sure a p28 ecu will work with it, and if so, i know a guys that has a p28 with a spoon racing chip in it for $75. so basically my questions are ... will a p28 work with ls/vtec? if so should i still plan on getting the GSR or should i get a 28? (which would be better performance wise) I know someone can help me cause Honda Swap rocks ^_^ and Thanks is advance. Even if you cant tell me all the ins and outs, lemme know what you THINK.
