Four cylinder FWD Chrysler Engines

How many different "families" of 4 cylinder inline engines has
Chrysler built since the K-car days, and, what are their available
sizes? Which ones are considered highly reliable and which are
shitpiles? I know that's a broad question, but is there a simple basic
overview?

Do they share the aft bolt pattern with the V-6's? Are some adaptible
for RWD and some not?

 

The 2.4 l 150 hp 4 in the PT Cruiser is very dependable if not just a bit
underpowered. In 70,000 miles I have never had an issue and it still
displays low oil consumption. I have always used Mobil 1 5W-30 and I change
it twice a year. At 40,000 miles I changed the ignition wires and put in
dual plat plugs. That's it.

There is a full description of the engines used in Chrysler products on
allpar.com.

I believe that "K" cars from the early 1980's, started with the 2.2 and
the Mitsubishi 2.6. The 2.6 was later replaced with the 2.5. 1995 was
the last year for the 2.2 and 2.5. A new 2.0 and 2.4 were introduced
for the cloud cars and the re-designed van for 1996. The 2.0 was not
available for the van.

The 2.2, from 1981 through 1995. Chrysler-designed, Chrysler-built. Sturdy
and durable. Power ranges from 80hp in the early carbureted versions to
224hp in the '91-'93 DOHC turbo version.

The Chrysler 2.5, from 1986 through 1995. Chrysler-designed,
Chrysler-built. Study, smooth and durable. Power ranges from 100hp in the
plain TBI version to 170hp in the seldom-seen intercooled turbo version
(150hp in the non-intercooled turbo version). Also built in a RWD version
for use in base-model Dakota pickup trucks.

The Jeep 2.5, from ?? to date. Not made in a FWD transverse version, only
mentioned here because it can be found in Dodge Dakotas, too, and is not
at all the same as the Chrysler 2.5.

The 2.0 and 2.4, from 1995 to date. Chrysler-designed, Chrysler-built.
Reasonably dependable; earlier versions tended to eat head gaskets. No RWD
version.

There was also the 2.6 (1981-1986), but it was a Bitsushitti design/build
unit. No RWD version.

No.

Wasn't that the same 2.6 used in the Sapporo? No RWD version I know
of in Chrysler vehicles, but there was a RWD version used in
Mitsus.

 

I think you're right, and *some* of those mitus used the Chrysler "baby
904" rear-drive transmission- which is the good old A904 in a more
compact case. But given the fact that the 2.6 had a new head casting
every other year, there's no telling if the block had the same bolt
pattern on the Mitsu cars as it did on the FWD Chryslers, either.

 

My guess is the 2.5 Jeep shares the bolt pattern with the 4.0 and 258
Jeep engines, a venerable design originated at Nash when MM was in
diapers.

Everyonne likes to rag on Mits, but their diesels are reliable, tough
little powerplants, as are at least some of their gas engines. Morbark
chippers used them for a long, long time. Thermo-King apparently used a
few as well, though most are Isuzu or MBZ powered.

How hard would it be to mate the FWD 2.5 or the current 2.4 to a RWD
trans and fab some motor mounts?

 

It was the same family -- the "Astron" engine, Bitsu called it. I guess
the degree to which I care about that POS is showing.

 

It might. It might not. I don't know, so I didn't say -- I regard that as
a better tactic than guessing out loud.

That's as may be. Not on topic, though.

Let us know!

 

Correction Mr Stern - there was indeed a RWD 2.6 - was installed in
the Challenger/Sapporo and mini Ram pickups and Raiders. Also
installed in the "fire arrow" and several RWD Mitsubishi branded
vehicles

 

Isn't the Jeep 2.5 a GM engine, like Luminas, etc. used?

 

1) No. The Jeep 2.5 is not the same as the GM Iron Duke.

2) There were *two* 2.5-litre 4-cylinders and a 2.2 used in the Dodge
Dakota. From 1987-1988, a longitudinal version of the Chrysler passenger
car 2.2 was used. From 1989 through 1995, a larger 2.5-litre longitudinal
version of the Chrysler passenger car engine was used. Starting in 1996,
this Chrysler engine was replaced by the AMC-Jeep 2.5, manufactured in the
Kenosha, WI plant.
