86 Chevy Caprice wagon

I have a 86 Caprice wagon. I wanted to know how hard would it be to convert from a gas engine to a diesel and what do I need to convert it over?

Right now I have a factory Olds 307 with 200 4 R trans with a 3.08 rear.

Might want to look at these threads:

Is the 6.2 diesel that GM put in their light duty trucks? Or is it a early Duramax? Never mind I just answered my own questions.

6.2, which was the precursor to the 6.5 engine.

The Duramax is an entirely different animal.

Is this a direct bolt in or is the a few mods that I will have to do?

Definitely a "make it work as you have to" project. Even transplanting a diesel into a vehicle that had the diesel as an option takes a certain amount of work. Transplanting it into a vehicle that never had it as an option requires a certain amount of customization to make it work.

You have a certain advantage in that the 6.2/6.5 has certain similarities to the GM gasser engines when it comes to bolt patterns and such - just because the trucks and Suburbans/Blazers came with both gas and diesel engines.

Being new to diesels,can I get a Crate 6.2 GM diesel?
Also will I need a ecm for this engine?

6.2 was mechanical injection. Early 6.5s were mechanical, but then went to electronic with an ECM. Chances are you aren't going to find a crate 6.2 as they haven't been used since '92.

Penninsular Diesel offers crate 6.5s: http://www.peninsularengine.com/index.html

Since you are converting a vehicle that didn't have a diesel to start with, the best course of action would be to buy a complete donor vehicle so that you can get all the associated parts. Otherwise you're going to be buying every little item separately.

i'm interested myself
