Picked up a non-running Quantum with the 1.6 turbo-diesel and 9Q 5-speed transmission. Body is actually quite straight with no rust, interior is acceptable (needs new carpet and a thorough cleaning). Am torn between pulling the engine/tranny and saving for a Caddy, or fixing the Quantum. It's been sitting for 5+ years so will need more than just the pump...

you dont find Quantums very offen and to find one with a good body is very hard. Fix it and sell it than find a rusted out one and use that.

Dobolina,

The Quantum drive train will not fit into a Caddy. The two photos below illustrate the challenge. First, the Quantum's engine bay (top photo) is 33" from firewall to front crossbrace, while the Mk1 Rabbit/Caddy's is 29". Second, the Q's steering rack tucks right up under the brake master cylinder and passes over the top of the rearward projecting gearbox, while the Rabbit's steering rack sits down low, right where the gearbox is. Third, the Rabbit's front wheel centerline is 21" back from the front crossbrace, while the Q's is 30", so the Q's drive line would be trying to stick out the side sheet metal of the Caddy. :shock:

Of course, you could always make a Frankencaddy by grafting the entire front end of the Q onto a Caddy, like Maarten's Dutch friend did with a late-model Jetta...

I vote to fix the Quantum and keep looking for a Caddy!

Actually, the longblock is the same...it's just oriented differently in the Quantum (parallel with the body line as opposed to perpendicular in the Caddy). The oil pan & manifolds have to be swapped out, but it will fit with those changes.

That said, I have a line on an injection pump so I'm going to have a shot at fixing the Quantum first.

Yes, the engine will fit fine, but you wrote "Am torn between pulling the engine/tranny and saving for a Caddy, or fixing the Quantum", which I took to mean swap the Q's drive train into a Caddy. Sorry about the confusion.

The oilpump, alternator+support and coolantline orientation can be different too, so using the Quantum engine will set you back a shedload of transverse engineparts. It's easier/cheaper to find a A2 TD and swap the enginemounts.
