2.4l pt cruiser turbo engine
« on: March 09, 2006, 09:36:05 AM »
I have a '97 2.5l tj. I have been doing some research and I was wondering if anyone knew if the 2.4l turbo engine from the pt cruiser is the same type engine as the 2.4l used in the newer wrangler? If so, could that engine be used as a direct replacement as the 2.5l in my tj? If not would i have to change motor mounts or anything like that?

The engine in your TJ is a 2.4L? I've heard they are the same engine and it will work. Someone chime in if I'm wrong.

Hmm if it is, I would think that it would have been done by now. It would be a simple swap.

Hopefully someone has seen this before and can speak to it.

The 2.4L used in the SRT-4 and the PT Cruiser GT is similar to the one used in the later 2.4L TJ's sans Turbo.  Spence and I have talked about it a lot when it first came out.

Problem is if you have a 2.5L, you need to replace a lot more stuff.  Then you've also got to figure out what to use for a transmission.  (I'd go Auto for simplicity.) The 2.4L's used the NV1500 5-speed.  The Auto was a 5-speed but I forget what model off hand.  Do a search.

So it would not be as simple as dropping it in place of my 2.5l w/ using a new ecu. It wouldn't bolt up with the ax-5?

No it's not that easy.

You would need.. motor mounts, ecm, wiring, transmission, transfer case (input gear is different) and either driveshaft or sye since the transmission won't be the same length. You would also either need to do some creative wire splicing, or just get the entire instrument cluster from a newer jeep as well. Plenty of work! :lol:

Wow, it sounds like the same amount of work need for a v8 swap. I thought maybe it would be cheaper and easier considerng it was a 4cyl. from chrysler. Wishful thinking I guess.

The problem is that it's not the same 4 cylinder as you already have.

2.5L vs. 2.4L

Honestly, I think the easiest way to Centrifugal Supercharge or Turbocharge the 2.5L.  The biggest advantage is that you'll have more lower end torque.  Keeping boost ay 7psi or lower and it should give you a nice boost without sacraficing engine life.

You'll still might want to upgrade the transmission and rear axle though.

No one makes a turbo kit.  Only Avenger makes a supercharger kit.  You're options are to go with Avenger or make your own. by piecing one together from misc. parts.

piecing together a turbo set-up is rather cheap/easy... You can use many turbo's that came on other cars stock (t3 or a 16g would probably do nicely). I highly recommend trying to run megasquirt or some other form of engine management. I plan to put a small turbo on my jeep hopfully this fall. The hardest part is going to be finding/having someone make you a turbo manifold... If you can weld there are a lot of people you can get flanges from. Or you could always go with a eaton m62 and fabricate it to bolt up where the a/c compressor normally goes. The ones off the mercedez slk230??? have clutch type switches to turn them on/off.

Thanks for the good info. I think if i tried to peice something together i would be in way over my head. Is there a web page that shows a step-by-step instuction for the jeep application.

I highly doubt there is any good if any write ups on putting a turbo on a 2.5L jeep. I'm only doing it because I owned an import before just buying my little wrangler and already know what i'm going to need to do (and have a apexi BOV and a little 14b turbo sitting in my garage collecting dust). If you just want some good turbo info for 4 bangers you can check out DSM,honda,wrx, nissan and srt4 forums (i'm sure there is webpages that are a lot more basic, but i used to roam most of those forums and thats where i read/learned a lot). If you have the time to read, and want to learn it's very easy to learn all the basics and start piecing stuff together.
