fuel rail

The 2.2 Chrysler engines used in front wheel drive vehicles are overgrown
copies of the VW 1.6 used in the Rabbit.  It was designed in the late '70s
when Chrysler copied the Rabbit, enlarged it a bit, and made the Omni.  The
2.5 appeared later and is a long stroke (over 4 inches) tall deck version
of the 2.2.  The 2.5 Jeep engine was the old Iron Duke Pontiac engine but
AMC later changed to its own 2.5 based on the 4.0 6 cyl.  Chrysler
continued to use the 2.5 AMC engine for a while in Jeeps.  I'm not sure
what 4cyl they use today.

Hey, something I know about (at least a little!)

The 2.2l (non turbo) and the 2.0 are very similar, and share a lot of
common parts, however have some overall block differences.

The 2.5L (as put in plymouth, dodge, and chrysler, not sure about jeep) is
not related to either of the above engines, was a different design
altogether.

The 2.6L Mitsubishi built engine ('79-83ish) was an excellent engine, a
little noisy in the valve area, but was considered a "hemi" engine.

I have experience with the 2.2L turbo, the 2.5L non-turbo, and the 2.6L as
I owned a few Plymouth Reliants while in college.

I thought the smaller Jeep engines were outsourced from GM?

Stephen,
	Do you know the bore spacing on the 2.5L Jeep engine?  I'm not sure if
that engine was a derivative of the 2.2L Chrysler engine or not.  I am
pretty sure the 2.2L Chrysler engine and the new 2.0L Chrysler engines
share the same bore spacing of 96mm.  If the 2.5L Jeep engine also shares
this bore spacing all you need is a fuel rail from a neon and you should be
set.
