I don't know if it is available that far back, but with my '03 I just had to get on the Jeep website and email them the last 8 digits of my VIN # and they sent me a 4 page build sheet that showed EVERYTHING that was on the Jeep. It was pretty neat to get and it only took about 4 hours to get it!!

Just go to your local dealership and they should be able to get you a build sheet right then.

What are you looking for in particular? I can check the O&M for my 94 when I get home tonight for you?

They just sent it right back to me, like 3 or 4 hours. Some people have said a few days, and i guess some people never hear anything. Hopefully they will get back with you.

it normally doesn't.

Just have to look up the specs for the engine - I'd imagine you can find THAT online somewhere.

Yeah someone can give you that. It's not like it would be individual specs for each vehicle. I will try to look it up when I have time and see what I can find.

Best I could find for now:

'91 2.5-L 4 cyl. comes with Electronic Fuel Injection (EFI)
Replaced 4.2-Litre inline 6 with 2-bbl carburetor with 4.0-L inline 6 with EFI. Max. torque increased from 210 ft-lb @ 2000 RPM to 222 @ 2,800 RPM.

Nothing changed untill 97, so it should be atleast the same torque spec for 94.

Here ya go george, a little searching and wikipedia here's what I found!!

"In 1991 Chrysler Corporation, then the owners of the Jeep brand, redesigned the RENIX engine control computer and raised the intake ports approximately 1/8″ for a better entry radius. Chrysler also enlarged the throttle body and redesigned the intake and exhaust manifolds for more efficiency, and the fuel injectors were once again replaced with higher flowing units. The camshaft profile was also changed. The net result of all these changes was an engine that made 190 hp (142 kW) and 225 lb-ft (305 N·m) of torque. Badging on Jeeps equipped with this engine read "4.0 Litre HIGH OUTPUT". The new cam profile combined with altered computer programming eliminated the need for an EGR valve and knock sensor, but make the engine more sensitive to alterations, especially where emissions are concerned."
