What is the issues with the R2.8? I thought it was basically designed as a TJ engine swap. I know that the JP/FourWheeler guys are supported by Cummins, but they have swapped in the R2.8 into dams near every small(ish) truck and SUV out there by now. Are they not holding up? Or is there some other issue that makes them less desirable than the VW TDI's? I've dreamed about a small diesel ever since the switch (US) to low sulfur. I got massively ill breathing around the old fumes. But then that stupid EPA fu@%ed it all up! So it's only doable (for me) with a swap into an older vehicle now.
