salgofnir you have a 4 banger. Look at the VW 1.9 or 2.0 TDI. I know there are those that think it is a waste and not big enough.

First you need to look at the power ratings of the different VW engines. With some new injectors and a tuner, you can get good HP and torque out of these. Go with a turbo and put a snorkel on it. Fab yourself a cold air intake.

Next go to Acme Adapters. They make the adapter kits to take a front wheel drive VW diesel and turn it sideways to put in a Samari or Tracker. This can be modified for your needs. You can use a Toyota 22R transmission (auto or manual) for the Acme conversion.

I have a friend that is going to convert a flat fender over the winter.

Here is a good mod page for a 1.9 VW diesel.

sublimemaze What diesel motor did the two diesel wrangler models come from the factory with? I know Mitsubishi made one, and one was made for airports on the international market with cooperation from Nissan?

jeeptj97 CostaRica Thanks a lot for all the replays, seems like is too much things to be done to swap to diesel also weight is problem, where I live no diesel options for jeeps, but at this point is better save some $ each month until the 4 cyl engine really dies. If before that I have enogh cash I will sell the 4 banger and take all money to change for newest model and 6cyl / 4.0.
Thansk again dear friends.

Also I just perfom the oil change but my mechanic insist to use 20w40 and no 10w30 as per the manual. He told me is because the temperature in our country (Costa Rica) is different than the US here normally is 90 degrees.
He said that oil must be heavier due to above explanation.
This is correct?

Many thanks in advance and kind Regards to all.
you could just use 40 weight thares no need for a winter rated oil whare u live

skeeter Your average temp isn't much different than many places Jeeps run up here. I don't think a heavier oil would be necessary.

As for the diesels. Are Wranglers offered from the factory with the diesel option there? If so you might be able to get ahold of one from a wrecked rig.
The 4BT is a popular swap up here, while it's a fantastic engine it's a bit large and heavy in my opinion for a Wrangler. There's a new Cummins option I've just run across that looks very promising. The B3.3, Here's a write up on one installed in an FJ45.

meyers Yeah due to your hot weather 20w-30 is fine. The biggest thing with a diesel swap is the weight factor. They are quite heavy for the Jeep. It can be done but it will take some work. Another way to go would be to swap in a used 4.0

snwchris Diesel Conversions... there's alot that has to be taken in account for as well as fabbing to make everything match-up.

Try the search function, it has been discussed before. But off hand the Cummins 4BT is the best conversion one so far to use. You'll then need to find a Tranny & Tcase, which I believe some are running the NV4500?? I think it was.

The biggest thing would be the weight of the engine as well.
