im asking for my frend he wanted to ask what would he need to do to put a d16y7 into his 86 crx, his block is shot i was wondering if we can just swap everything over and ill work. i havent seen his engine bay jet so im not sure

 

lots of work more then its worth, you will have to make custom mounts as nobody sells them for that swap. it has be done though but even those say they will not do it again. check out http://www.redpepperracing.com but do a search first or you will get flamed as this question has been asked a million times there.
