Hi. I'm brand new to the forum. I'm looking to buy a Wagoneer, restore it, and swap in a diesel. Being in CA, this presents a series of challenges that seem to have been well documented in other threads.

After talking to a smog referee, it seems I can jump through most of the hurdles if the engine is newer than the Wagoneer, I'm not mixing weight classes between engine and vehicle, and the intake and exhaust assemblies are stock for the year of the engine.

The weight class issue pretty much limits me to a 6.2/6.5, which is fine for my needs. It also seems to be an easier swap than the 4bt, etc.

I understand that the 6.2 is dimensionally similar to the small block Chevy. Being an almost complete noob (not quite--I did an engine swap years ago) I was looking through Novak's fsj engine installation guidelines, which say that the factory manifolds for the gm gas engines won't work in a fsj because they interfere with a lot of other parts. Is this the case for the 6.2 diesel as well?

No problem with exhaust manifolds. Not so lucky with the factory heater box and vac booster. I modified my stock heater box and upgraded to hydro boost. The difficulty of the swap is dependent on your skill level and resourcefullness. The most expensive part of my swap was getting the 700r4 rebuilt.
