I've been looking for a VW TDI for some time (mostly for the fuel economy), but it's been tough. Most are prim and proper, and even ones with high mileage are $$$.
A fella that I've gotten in touch with has done a swap of a 1.9 TDI (supposedly with around 80,000mi) into an '81 diesel Rabbit pickup.
Nothing could give me jollies more than a Rabbit pickup with the balls of a TDI; however, what should I watch for as indicators of a poor swap?
He's used the stock Rabbit 5-speed (FN-15-104), which should have similar ratios due to it being a stock diesel... However, I can only assume it has "shorter" gearing due to the fact that it used to have a wimpy little 1.6 N/A diesel in it stock.
Any idea if a 5-speed from a TDI of some sort could be adapted easily to give the taller gearing (if it is an issue)? Don't get me wrong, I drive 55 everywhere I go to keep RPM's low and save on fuel (hypermiling)... I would like to be more comfortable on the interstate soon, however, since I'll be making a long ass commute twice a week due to the new job.
Advice on signs of wear on the engine are appreciated as well.
