Hi all, I've been searching around looking for answers to my questions. It would be nice if all the information was in one place instead having to do 50 searches. Anyways here goes. I have a 73 240z. I'm looking at installing an SR20 - not sure which model. I Plan on buying a clip from a silvia to help with parts. From what i understand I will need custom made motor mounts and mounts for the transmission. Does anyone sell mounts for this conversion? Next can I use my stock rear end? I understand the my driveshaft has to be shortened. How much shorter does it have to go? How much power can it take? If I want to keep the motor stock can i use the wiring harness and the ECU from the silvia? or will I have to go with a standalone. I was planning on just running a custom 3inch down pipe and exhaust. Thanks to all who have any positive input.
