I’m looking to put a jdm h22a1 engine in my 92 prelude to replace my h23. I’m trying to find someone who has done this swap and can tell me of the problems that come up, I know the engine is a bolt up to the transmission and mounts are fine. But are there issues with the wiring harness. How hard is it to wire up vtec. I just want to know what else I have to prepare for when doing a swap so I don’t plan on taking more then 2 days to do the full swap.
