Dash wiring loom, engine wiring loom, trans wiring loom, engine ECU, Trans ECU, diff, console quadrant and console wiring.

Not sure if the EA 4 speeds had a double TPS or not. If it does, you will need them.

The diff is optional, but it is the whole reason you'd want a 4 speed. A shorter ratio to improve acceleration, along with a more efficient auto.

Plus at 100km/h you'd be doing something silly like 1500rpm if you kept your current diff.

Yeah. It doesnt stop you getting a 3.08 or 3.23 diff elsewhere.

Or if you can get your hands on a 3.45, even better. :D
