I'm buying my neighbor's 1993 Eurovan for a song. It's in great shape with the original 2.5L 5 cyl motor and 140,000 miles. It should last a while longer but it gets horrible fuel economy (17-20 mpg) so I'm naturally considering a TDI. I've heard the 5 cyl diesels & TDI's drop right in, the TDI needing a new ECU. I'm wondering if the 1.9L 4 cyl will work. I looked around on-line without luck. Anyone done this or familiar with any other TDI swap-in with the Eurovan?
