Gas to Diesel conversion?

[DieselSteed]

Just picked up a Jetta MK2 in mint contion. Only problem....Its not a Diesel. How many volks out there has made the conversion?

i almost bought a mint mk2 wolfsburg ed jetta... deal fell through (thousand bucks, everything was mint, but the motor was dead)

as far as i know, all you need to swap in is a bigger battery, and get a diesel wiring harness (to make things easier) and a different downpipe/exhaust.

i think you can do it without swapping the harness, but you will need to wire up the glow plug relay and a light...

Cody on dubnet did it.

He used a mk1 diesel engine though, so a few of his steps don't apply if you are using a mk2 or early mk3 diesel engine

I did the swap on mine. It was pretty straightforward. In fact the hardest part was figuring out what parts I needed and locating them. I've put over 10k miles on it so far and no major catastrophes yet.

Oh and I just wired up the glow plugs to a relay and pushbutton. The fuel shut off solenoid got connected to the ignition coil power wire, and I kept the lift pump in the fuel tank and put the fuel pump relay on constant ground so it runs whenever the key is on.

The fuel inlet restrictor met it's demise with a hammer, chisel, and a pair of long pliers. Now I can fit any nozzle I want in there including the biggest truck nozzles.

Ask me any more questions you've got.
