Well I bought a Turbo 2.4L out of a PT crusier to day, I will be replacing my 2.4L out of my jeep it only has 17,000 miles on it.
the new engine only has 400 miles on it so it should be a fun conversion. I have some clearence issues but nothing big I will be writing and showing pic's as I go

Here's some info for you:
Engine Configuration I
Cylinders 4
Aspiration/Induction Turbocharged
Displacement 2.00 L | 122 cu in. | 1999.6 cc.
Valvetrain DOHC
Horsepower 215.00 BHP (158.2 KW) @ 5100.00 RPM
Torque 220.00 Ft-Lbs (298.3 NM) @ 2800.00 RPM

Conversion

Converting an engine designed for FRONT wheel drive to REAR wheel drive will be interesting for sure. It looks like all the turbo stuff will be right up against the firewall with little if any room for the hoses.
The radiator hoses will be much longer.
You might want to consider if the transmission can handle the torque.
Will a new computer be required?
Good luck and take lots of pictures. :thumbsup:
Thanks.

My guess is that you just turn it 90 degrees.

longer/ rerouted pipes/hoses.

i would imagine that the existing motor mounts will work just fine with the engine.

i wouldn't imagine that installing the motor would be all that bad, really. need an adaptor for the tranny, some custom stuff here and there. but a lot of the electronics should be compatable with the existing stuff. it has got to be no harder than converting a 2.4L to a 4.0L

im looking forward to seeing how this turns out. not that it helps me because i have the 2.5L, but its cool to see this tried.

Well seeing what that engine was pulled from ,the tranny may just bolt right up.The 2.4 standard engine for the jeep IS the same engine that is used in the PT. : http://en.wikipedia.org/wiki/Chrysler_Neon_engine#2.4

It will bolt right up to the trany no problem there.

all of of my sensor's will bolt up to this engine too.

I'm still think about just swaping both intake and exhaust manifols over to my engine so I don't have to swap engine and keep this one for a spare it only has 400 miles on it!

The fire wall issue is the bid problem but what I am going to do is. Take the exhaust turbo manifold off and flip it 180 degrees so the turbo is facing foward there will be no clearence problem then. the exhaust will be in the exact same position just 7" high, the exhuast flange is parerall with the engine block so it will look the same just 7" higher.

There is no difference between my engine and a sideway mount engine just hose have to be rerouted , but my engine is the same so I just use all of my stuff and swap it over so far everything is in the exact same spot

I have the Computor and all of the wiring for the Turbo engine that came out of the car too.

There are some lines on the turbo that have to be addressed I'm waiting for the parts manual to figure this out

my thought was that a stronger tranny would prob be used for the turbo motor, so a little modification might be needed there. but, it seems there won't be

Why not take the turbo assembly and stuff from the PT engine and put them on your jeep then?
can't just swap the turbo to the existing engine because the internals are different. the turbo motor runs lower compression pistons and has most likely has forged internals to withstand the higher pressure. swapping the stuff to the n/a motor he would have to run very low boost and would still risk melting a piston or punching a rod through his engine.

True.. and there are some oil ports for the turbo oiling system that are not on my jeeps 2.4L............

Sounds good to me. ANd I have not seen a real build thread on here since I can remember. I say leave your motor in and just swap out the intake/turbo stuff. Your engines "internals" wont matter because neither is a high compression motor. Now the cam you currently have may not be otptimal for the turbo setup you may want to check into that

there is some oil line issue's if I use my old motor There turbo oiling lines holes are not drilled on my jeeps 2.4 and they are all set up on the PT motor

Well, I am not sure on the requirements for oil flow on that motor (but its a pretty small turbo) - I know on the Turbo Regals (which I am VERY familiar with), all we do is put a "T" fitting on the oil pressure gauge/light sending unit port, and drill and tap a return port to the oil pan (when using an old NA block).

I would use the turbo block, almost guaranteed it has lower compression then the NA. Again, I am not a DC expert, but I bet the NA block is at least 9:1 and the turbo will be closer to 8. Unless you are going to run an Alky injection setup, or keep the boost low, you will take out the rod bearings when you detonate it. Or pop a head gasket.

Also, does the NA block have a knock sensor tapped in as well???

If the turbo block bolts up, use it. You are going to have a hard enough time getting both computers running together and getting the plumbing and exhaust right.

we don't have knock sensors. just toss the whole thing in there. i love wrenching on my rig as much as anyone else, but i try not to look for reasons to make things more complex.
edit:
i wish i was there to help you out with this man, it sounds like a lot of fun.
