Getting serious about swapping my gas motor for a diesel, does anybody know if I need to re-do the exhaust and ful tank to go with it? Its for an 80 rabbit pu if that helps at all.

Going the same route in my scirocco. Stripped, lowered, lightened, high gearing, super economy machine. I want to go dual fuel with it eventually too. I hear putting diesel in the gasoline tank loosens up all sorts of crud. As far as exhaust, it bolts up the same, and I don't think the cat will hurt anything, but you can always gut it out and bolt it back in place. I traded a used trans for a diesel rabbit parts car that has all I need to swap over. Just too bad it's not a turbo! :o

Thanks Ranger, I'll see about cleaning it or something, good luck on the `rocco.

Not sure about the gas tank, but I do know that if you put a diesel engine in a gas car, you must also swap the tranny! A gas tranny is geared different than a diesel tranny. If you get a diesel exhaust system fron the clip-on downpipe back, the hangers should all fit, even on the gas car.

Use the old trans. In my caddy diesel I experimented with GTI A-1 and other trans, found a 9-A worked the best, the diesel pulls all the way to 85 mph with no problems.

Tank should be no problem, all you need is fuel flowing out, the A-1 Rabbit should give you plenty of parts to work with.

Chuck the computer and electronics, all you need is the simple setup for alternator and fuel swtich on the pump :P

Do be aware that Diesel fuel will eventually react with the galvanized coating on gasoline tanks. Diesel tanks are not coated. The Zinc of the galvanization process will quickly clog a fule filter once it begins to come loose from the metal... [-X
Happy Motoring.
