I searched a bit, but it seems all the real swapping starts with having a gsl-se.

I can pick up an entire 88 rx7 donor car, running, t-boned for $150.

I want this motor in my 85 GSL, and I know I would have to run wiring for injectors, sensors, and such.

Are there any good write ups on this? Or if anyone else has done it, what problems should I be ready for?

 

The only advantage to having an SE is you can run the external fuel pump without major mods to the tank.

Any TII or 2nd gen engine swap info is pertinent,its the same work to do N/A or TII engines,and the majority of the work is the same between S4 and S5 engines as well.
The left side custom wiring and setting up the fuel system are the biggest hurdles,just do searches on those specific items if you get stuck,its been covered a million times.....just not really all on one big thread.Trust me,this is BY FAR the most asked question,and its been covered over and over.

 

Cool, gracias!
