Ok, I am buying an LS motor for real cheap, but there's missing parts. I was hoping you guy could help me. I am just buying the motor itself. He said there's not ECU.

What all am I missing? ECU, Tranny, and?
I am swaping into an '00 Hatch. Could I use GSR motor mounts?

 

It's a '96 motor. I found a '00 Tranny. Would I need a '98-00 ECU (OBD2)? What shift linkage could I use?

 

Try and find a complete swap. it will probably end up being ALOT cheaper in the long run and save yourself alot of searching and problems.

 

complete swap is much easier unless you have experience with swaps. Just some advise, find a GSR tranny instead of an LS
