I'm helping my brother to put a H22 (year 92-95) into a 1990 civic Hatchback. I have not been able to get a clear answer on what harness I need for the dash conversion and what tranny, axels ect. we will need. Can any one please help on this?

 

you need mounts to start off with. so once you figure out what mounts your going to use. then the rest kinda has to fall into place. and your going to need a h-series tranny. or a b-series tranny with and H2B kit. b-series tranny doesnt just bolt up to an h22. check out the site

thats where i bought my mounts from and they are good quality for a good price. Jon is very helpful to when you have questions or just want some info.
