Are These 2.4L not the same as the 2.4L that went into the TJ SE's? If so there are TJ guys who have put PT Cruiser turbos on and ran with no problems other than figuring out how to install them to be useful for crawling. I was searching the compass forums to see if anyone has done it yet and am a little surprised I haven't found anyone who has done it yet.
Different animal. These are 2.4 VVT engines, new design.

Still thinking on it. Use the turbo from the Caliber SRT and do about a 4lb waste gate so that my CVT doesn't self destruct. I've talked with a few guys at the dealer about it.
Artificial intelligence is no substitute for natural stupidity
I got a few friends who are into turbos and what not, just I don't know how we can treat these new engines and what not...thats the only thing I need is to blow it up! lol...
i'd like to just wait for a srt4 to be found with engine in tact! so I can take all the stuff off it since its the same engine! and it should all be good then..do some custom piping...and bam
you can build a turbo kit that will run 5-10lbs of boost for a rather reasonable price. at this point the only problem i see is the manifold. It would have to be custom made since no one makes one yet. Unless the SRT's manifold uses the same bolt pattern?
Please feel free to add to it if i missed something.
Manifold (with matching turbo flange)
Wastegate (if not internal)
BOV (blow off valve)
Custom downpipe and exhaust
Custom pipes and intecooler (or just pipes to rout the intake if running less than 5 lbs of boost)
Fuel and spark controller (safc, e-manage, etc)
Larger injectors (not sure what size the factory uses but you may not need to replace them if only running 5lbs of boost)
wideband o2 sensor and gauge (for proper tuning)
EGT (exhaust gas temp.) gauge - from my experience with supercharging a car i learned that these are handy for tuning to ignition timing. If you run too much timing youll get detonation, not enough and your EGT's will go up and burn out the turbo's bearings and the CAT-converters.
For those of us with the CVT we would probably want to run an aftermarket Transmission cooler as well.
I would say a good kit would cost around 2500-3000 with the custom fab parts. If you have a shop do the tuning you could eliminate the cost of the widenband and EGT gauges but i would still recomend having them eventually. For those of us that are crafty you could probably fab a kit for around 1500.
I think its been discussed here (cant remember the thread offhand) and (I think) the general consensus was that the CVT tranny will explode. just doesnt have the HP/torque rating for a turbo.

My understanding is the reason why there isn't an AWD SRT Caliber is because the AWD system can't handle the 300hp
It possibly can if you can swap it out with some Lancer guts, I'm not sure how similar the components are. The SRT 4 Caliber has the 6 speed Getrag transmission. Maybe a manual compass can handle the same. I think the Rallye edition should be Jeep's version of SRT to begine with
