yes, i've searched and searched til I was blue in the face and can't seem to find a straight answer. I might be purchasing a 93 Civic EX to replace my '90 civic. The 90 has a LS out of a 00 teg. If i were to buy the 93, i'd like to put ls motor in it. I was wondering what mounts I need, and what wiring harness do I need? will the one from the 93 work for the 00LS motor? can someone please give me a straight answer?

 

i think youll just need b series mounts. as for the wiring harness? im not too sure.

 

well ull need a ecu and a conversion harness depending what ecu your runing iin the 90 .. obd0,1 or 2 i was use a conversion harness to obd 1 and youll need motor mounts id use after maket but if you gonna use oem use a gsr side mount most important you need a hydro tranny u didnt mention that part if you have one or not your 90 civic is cable transmission if your not going turbo use a b16 or gsr shorter gears = faster times its gonna cost some money though bout 500 and especialy a round here in mo might be hard to find unless you got a hook up i live in fort leanard wood currently and parts r a lot harder to find a round here then they are in socal

 

i'm running an obd1 ecu and have a boomslang jumper harness currently on the '90. I had planned on buying a new tranny for the 93. I do plan to turbo it eventually. so a tranny from a '00 teg ls isn't hard to come by for $200. but my question is, on a 93' what engine wiring harness do i need?

 

B series mounts, use stock harness, OBD1 LS dizzy. i think you might have to change some sensors (plugs might not match).
