DONOR CAR
Here are a few notes to be taken…….
- Find a car that hasn't been gutted yet. Its a lot easier to sell off what you don't need then to scavenge for what you do.
-If you are doing this project on a budget, there are a few things that can be done to help keep some hard earned clams in the bank.
-Use the stock exhaust manifold / down pipe. It will have to be cut short and at an angle to clear the steering rack, but works just fine.
Here is a list of everything you will want to pull off of your donor car
Transmission
ECU
Full engine harness (take as much wiring as you can, you can strip off what you don't need later)
Cable shift box
Fuse box
All coolant lines
Oxygen (O2) sensor front sensor
Guage cluster (if you want to go that route, I will show how to get everything hooked up)
Gauge cluster harness
WIRING AND STUFF
This is the Mk3 fuse box showing only the harness point that are needed to make everything work including the speedo cluster.
I have blanked out everything that is not needed in an effort to make this simpler to read.
Here it the breakdown of whats on here.......
