2001PT 2002PT 2.4 swap?????

[80demoace]

I have a 01 PT with a rod through the block in the N/A 2.4. I have can get a 2002 2.4 N/A really reasonable ($400) in running condition/low miles. Will this be an easy swap or not. I am not a dodge person but I have been an auto/school bus mechanic for 10 years. If the swap is fairly straight forward it shouldn't be a problem, I just don't want to buy the engine and find out they are different and won't interchange. Thanks JK

Should not be a problem... Should be a straight across swap.

Fitment won't be an issue, but I'm pretty sure you'll need the pcm from the '02 and have to have your VIN flashed. I seem to remember the control modules were different for those two years.

Shouldn't be a problem. The base engine was pretty much the same from 01 till 04.

I had an '02, and there was essentially no difference from an '01. In '03 they managed to get rid of EGR, but '01-'02 should be straight swap.

Thanks guys- I think I will get the 02 engine and try to get the pcm with it.

You don't need the pcm from the other engine. Every thing will just plug a play.

Yeah right. You've done this before and are positive there are no programming differences between '01 and '02? I know for sure their were programming changes because the auto tranny was handled by a separate ECM for '01. Not sure if it was '02 or '03 when it was all combined into the PCM. I know there were programming changes for '04, but not sure about '03 so your "no changes from '01 to '04" is wrong. 80demoace, get the '02 pcm just in case.

Mechanically there is no difference. That's all you need to worry about.

The PCM should have absolutely no bearing on his install if the block is entirely the same.

I'm new to PT, but my last car was a Mazda. Mazda used the KLDE engine from 1993 to 2002. Even though a 1993's computer was completely different and OBD1, while the 2002 was OBD2 with a distrubutorless ignition ..... you didn't have to change computers. All you had to do was swap over your distributor system. But you leave the current ECU.

No matter what engine swap you're doing there are only two important things to look at: the small block casting and the sensors. If the casting is the same, this allows you to bolt up the new block straight to the old motor mounts with no modifications. If the sensors are the same, then the wiring harness and ECU should be able to be maintained (as long as the new block is within a half compression point). There may be minor long-block updates like different crank materials, or oil pumps, or intake manifold, or whaterver else might be updated over the course of a manufacturing run ...... but if the casting and sensor array are the same, it should be a no-brainer to swap over. The only things that usually effect the swap are auxillary things bolted to your block, so you just need to use the parts off your old block instead of the ones that came with the new block. If you're a mechanic right now, you should be more than fine.
