Glad I found you guys on this website. I truly appreciate the info you guys are passing around.

Hope you all can pass some knowledge my way.

I have a 99 Trooper 3.5l gas, great shape. Want to convert it to small(er) displacement DIESEL. Short term goal - better fuel economy on my 4x4. Long term goal (hopefully not too long) - making my own biodiesel.

Would consider buying a diesel 4x4, but there are not any older 4x4 diesel's around here (or at least I cannot find them).

Questions:
what engine should I get?
where can I get this engine?
am I crazy?

Thanks to all.
