thenafter SLOWLY make adujustments to the wastegate to increase boost.

happy smelting!
Hmm, my 1980 1.5L NA diesel Rabbit was (IIRC) about 22:1...I wouldn't call that "low compression". As for the squirters and intercooler, those are nice for performance, but wouldn't be needed for someone interested in recreating an ECOdiesel of the early 90's in a first-gen Rabbit. One would also need the turbo-to-pan oil drain line and the oil pan from a TD Jetta or Golf.

That said, I'd be all over this offer if Ryland in my neighborhood.
Best tank ever: 72.1 mpg in February 2005, Seattle to S.F.

Thanks to 'pulse-n-glide' technique.
