Ok so I know it's been done. But was wondering if anyone has a write up or can give me some info on it. Like what waste gate, turbo to use, any junkyard turbos I can use, computer stuff, etc. Thanks

Jeep 2 cylinder? Is that a typo? Exactly what Jeep do we have here?

Wow lol, yes a typo. I was thinking too much. It's a 2.5l 1995 jeep.

I'd probably go with a readily available turbo with built in wastegate off something similarly sized - probably a Mitsubishi 4G63 out of an Eclipse. Tuning it may be a bit of a challenge; if I were doing it myself, I'd probably use a MegaSquirt standalone ECU and aftermarket crank trigger. If you're trying to do this super cheap, an OK "band-aid" option would be a rising rate FPR and a timing retard device like an MSD Boost Timing Master.

Note that Chrysler's 2.5 Turbo from the '80s is not related to the Jeep / AMC 2.5.

With megasquirt, do I want one made for my jeep, and do they come with good directions. Also I am not quite sure what a crank trigger is. Any other parts I made need, any how tos are handy. Thank for the info so far.

The MegaSquirt directions are all online, so you can go over them and get questions resolved before you decide if you want one:

We can build them with custom mods if needed, or if you're feeling up to building one from a kit, you can. The MegaSquirt would determine engine position from a sensor reading a crank mounted multitoothed wheel. See these articles for examples of setting them up.

You say WE...is that meaning you(or a company). Also I know this isnt a topic on this site really, but I am actually going with a supercharger. I am guessing I'd need all of the same type stuff?

Matt Cramer

Yes, I work for DIYAutoTune.com. So I can set up an order but I'm not the one who assembles it. Tuning needs are similar for supercharged and turbo engines, other than that a blower uses purely mechanical boost control.
