before somebody locks this thread you will need…
ka24de engine (obvouisly) lol
Wiring Harness
91 power steering pump and lines
cluster
the transmissions mount up…but as for the time for doing the swap and all the work involves many people will say go sr or rb, or ca…but i think its worth it if u do the work urself
umm thats all i know only other thing is keep searching there is a detailed technical thread about how to do this swap somewhere around here just keep searching

You also need the ecu for the DOHC
Power steering lines are a good idea but not required.
I could do this swap for you in less then 10 hrs for a minimal fee of course. If you have any questions pm me and I could give you a price.
I also just noticed that you are local, even better for you. Are you ever in the st kitts area?
