In reply to # 1595120 by clshore The VW 1.9 tdi:

Horsepower
From 1996 through 2003, the 1.9-liter TDI created 90 horsepower (hp) at 3,750 revolutions per minute (rpm). In 2004, Volkswagen tweaked the fuel injection system, after which the 1.9-liter TDI produced 100 hp at 4,000 rpm.

Torque
From 1996 through 2003 the 1.9 TDI produced 155 foot-lbs. of torque at 1,900 rpm. In 2004, the torque jumped to 177 foot-lbs. at 1,800 rpm. It remained there until the engine's discontinuation after the 2006 model year.


What are your plans for the transmission?
I'm not aware of any RWD VW diesels, but perhaps one of the RWD transmissions from VWAG will bolt up: Porche, Audi, etc.

The Spitfire drivetrain is barely strong enough for the stock motor.

The Subaru R-160 diff can be fitted to a Spitfire without any frame or body modification, using available adapters.

Another candidate if you are considering frame surgery is the Ford 8.8 IRS diff, and there are ring&pinion gearsets as tall as 2.24 available,
more suitable for a diesel RPM range and torque.

I've got a T5 from a 5.0 mustang and a bellhousing to mate it with the engine. It is going to require some frame tweaks, but the torque rating is like 300 ft-lbs so it should handle the rough diesel power strokes. I have a GT6 3.27 rear end to get the engine speeds I want, and I am well aware that it is the weakest of the already weak stock diffs. I plan on building my own rear suspension some time later, so I'm just going to have to try to behave until I get around to it. Or it blows up regardless and forces me to do it faster.

The stock axle/s might turn into spaghetti if you nail it .

To the original thought...…. Great!! if it works - it works.... no matter how you made it work...… beauty is in the eye of the beholder....

More likely is that the tires will turn into smoke ...

In reply to # 1595081 by Bkunka It may burn the differential off too, but that's a problem for another time
Have you ever noticed how the differential looks like a big old hand grenade ?

........heh.........

Get a grip guys ….

The 1.9 TDI has similar HP and marginally greater torque than the GT6 motor.
And for those fitting TR6 motors, the numbers torque numbers are on a par.

Yes, the TDI torque is delivered at lower RPM, but redlines are significantly lower, so
diff gearing must be taken into account.
