Do plenty of reading and alot of searching. That is how most of us whom have done this have started.
Suggestion one; Get wiring diagrams for both the GN and for the car you plan to swap all into.
Suggestion two; find a donor but remember these things are shooting up in value so keep in mind you may want something that is beyond saving as it is only the mechanical and electrical you will be using.
If wiring intimidates you contact Caspers and he will build you a harness to interface with your car and it will almost be just plug and play.
You will need an electric fuel pump.
I actually used my Cutlass harness and added power to the fuse block for the injectors and pump. Later I pulled the dash and went through every wire and put in a GN dash harness just because I wanted to make sure everything was correct.
Your earlier cars don't have a computer or all the extra crap that my Cutlass did so interfacing the new into the old shouldnt be too dificult. All other electrical systems should be fine without modification.
The rest of the work (rear end , etc) is basic hot rodding, what fits and what parts are accessible to you.
There is a guy on here who used to go by Bandit who sells CD roms of the factory manuals for these cars. Best $$ I spent on this project.
Also do a search for turbomonte and wagon or gnwagn, and s10gn ( I am listing these names from memory so sorry if they are wrong). They all have websites dedicated to their buildups. Oh and GNX7 did one in a RX7.
Post any other questions you have.
