4.0 high output

I used to own a 1993 Cherokee that had a 4.0 high output engine. It seemed to have alot more power than the 4.0 in my 97 Wrangler. Does anyone know what they did different in the high output 4.0?

The 97 4.0 is also considered a 'high output'.

Basically the same engine. Mine has the 2.5L "low output" version.

Gears could be the "more power" you were feeling.. Your '97 may have crappy gears.. Cause the "high output" was just to make you feel better about yourself...

I had a 93 HO wrangler and it had a lot more balls. I think emissions and the gearing play a large roll in how well the jeep preforms. Just my opinion though.

This is probably the case, especially if you have 3.07s

Anyone know the stats of both engines (HP and Torque)?

My 93 YJ had 3.55 gears (IIRC) and seemed to have good power, I would almost say it was better that my TJ. Both were 4.0l Autos YJ had 3.55 and TJ is 4.10.

But I am also nearly 10 years removed from driving the old yj so my memory could be off.

Your TJ with 4.10s is on 33s, which would make a difference.

According to Autotrader tech specs for Wrangler:

93 4.0L: 180 hp @ 4750 rpm, 220 ft-lbs @ 4000 rpm
97 4.0L: 181 hp @ 4600 rpm, 222 ft-lbs @ 2800 rpm

Also TJ weighs about 150lbs more than a YJ yet gets 18mpg hwy, vs YJs 16mpg.

The 2000-06 4.0L Wranglers are

190 hp and 235 lb-ft

Increase was due to a re-designed cylinder heard, re-designed intake manifold, re-designed exhaust manifold and the distributor-less ignition

Any noticable difference between the two probably had more to do with the gearing and curb weight than the engine itself. They are basically the same engine with some minor differences.
