Ah, yes. Another Californian for biodiesel or WVO. Go figure. I had the same idea a few months back. Gee... I love my trooper, but it goes through $3.00/gallon+ gasoline as fast as a cigarette boat with a fuel leak. In sharp contrast, my Passat TDI approaches or passes the 900 mile mark before I have to fill up the tank. If I could convert it to diesel, and brew my own biodiesel for under $1.00 per gallon, I could afford to keep driving this thing and it would be easier on the environment too. Is that what you're after?

From what I've heard, here in California, (if that's the Orange County you're from), the smog referee lets you swap in any diesel engine of the same year or newer that's not industrial, agricultural, or from a heavy truck.

To my understanding, that sorta narrows it down to the trooper's original optional diesel engine (rare in this country, difficult to get parts and service for, etc.) or a TDI from a VW (slightly more popular and easier to get parts and service for) or a diesel engine from a Mercedes (perhaps most popular and supported, but probably more expensive)

I vote for a late model Mercedes diesel. I gotta be on the lookout for a rear-colision-totaled diesel mercedes and get the engine ECU and trans and trans ECU out of it. Swap all that stuff into my '90 trooper. My question is, how do I match the output of a Mercedes trans to my Isuzu transfer case, or to any transfer case, for that matter. OK, all you double transfer case hot dogs, how can I do this?

My second choice is the VW TDI engine. At least late '96 or later (ECU controlled injector pump). I would try to marry just the engine to the 4L30-E auto trans somehow and pray the trans can take it. I'm sure the engine's not as strong as the Mercedes, but re-chipping and various other tuner mods should get me close to the torque output of the old 2.8 GM V-6.
