in reality the turbo'd engine out will be easily increased a LOT, more boost with proper fueling + timing adjustments can easily add 50 hp + torque on a modern direct injected turbo'd engine!!! free flowing exhaust will allow quicker + a bit mote boost even without an ECU tune!

That is true, even a manual boost controller can give a noticeable increase in power. But, from someone who is very familiar with turbo engines. With a turbo comes a LOT of heat, & with the batteries & all with that 2.0L, I don't see where a turbo would be good for a rock crawler. Now, for pre-runners, track, or something where fresh air is constantly moving over & through is best on a turbo engine. My turbo car is mid engine & at an autocross I have to raise the engine lid & stick a box fan on top of the strut tower bars to cool everything down before making another run. Because when that turbo heats everything up, the engine computer will pull timing (& up the fuel pressure) to keep knock at bay & that robes you of that extra power. Delicate balance for sure.

Back to OP...
You really have to question the sanity of some dealerships. Yikes, that is hideous.

a well designed turbo'd engine will have oil + water cooled turbo's + an after run water pump, otherwize idle it to let things cool while the fan + oil circulates. on that last note the very best oils to handle high heat + prevent coking are ester based + RedLine's products come to mind, also as temps increase oils continue to thin past the warm spec given @ 100C here again a true synthetic group IV PAO + or Ester oil thins less as the heat rises + if you need to DON'T be afraid to use higher viscosity oils, BMW specs a 10W60 because they believe their owners will use the car as intended, track days included!!

That's for sure. Good fluids are a necessity. I was just thinking of the heat under the hood, that is what will wear out the belts & hoses & help the computer to retard timing to control knock.

I do think it would be interesting to know if the Jeep turbo will come with a built in turbo timer & to know what the boost range & max boost pressure is, & where fuel cut would come in to play. Knowing that will determine how far you can push it. ;)

proper AFR's will help control heat, of course the OE tunes are for mpg's + EPA specs + as noted a choked up exhaust slows the total process. lots can be done BUT not by the manufacturers as they try to meet the requirements for noise + pollution!! todays DI allows a lot more aggressive tuning as it controls knock soooo much better, but theres the carboning issues as the intake valves are NOT cleaned by incoming fuel like on port injection. its early but time will tell as the turbo's engines see real world driving + the miles pile up!!
