Saturn TDI for S-Series

Hello -

I just found this over at saturnfans :

Saturn TDI

Heres a thread from the Sixthsphere.com forums of what I've been up to.

This came about from the first big price spike in oil we had a couple years ago. I had done some reading on running a diesel on vegetable oil and biodiesel, and the idea of running my wagon on it became very appealing. Thus was born the idea of swapping a diesel into a Saturn, and a couple years of reading, researching, and thinking. The project finally got started in early August with the purchase of a 1.9 litre VW Jetta TDI drivetrain, and mocking it up into a 1995 SL2 to sort it all out before making the swap into my '95 SW2. Most of the time I've spent on it so far is in getting the motor located and fabricating the mounts. Once I get it bolted in place, I can forge ahead with the axles, shift linkage, wiring, cooling system, and intercooler plumbing.

Hope he can pull more than 50MPG with that setup. Will be interested to see this project through and see the outcome.

...why?

I could see doing this with an ultra-low-weight car, but why move a TDI from a VW to a Saturn..?

I guess if you had a non-running Saturn and a TDI engine just sitting around, then it might make sense, but otherwise you would be MUCH better off just getting a VW with a TDI in it to begin with!!!

Because he can! If he's registered at sixthsphere, then he is probably a Saturn junkie.

He may be going from 3000 lbs to 2300+ lbs. But, again, see above.

So far I've seen 'em stuffed in a Suzuki Samurai, Toyota pickup, and all sorts of VWs (Corrado, Rabbit, etc...).

A Saturn weighs as much as an older VW, and has half the drag coefficient/reference area. Should be good for ~70-80mpg@55mph.

Thanks for the correction. I was going off of the curb weight of the newer 2006 models.

Wow, considering the only four door TDI available was the Jetta, that engine's gonna have ~1000lbs less to pull around. It'll be similar to a TDI in a bunny, some of which run high 13s quarter miles w/ mods and can get ~50mpg@70mph, except it'll be a little slower, and get significantly better highway mileage.

Alright then, I stand... informed. Perhaps I should have looked at some weight references before commenting.

I should say that I own a Jetta TDI.

It's np. If I lost a tooth for every time I had to stick my foot in my mouth I'd need dentures before I hit thirty. :D
