6.4L -- I would still put turbos on it ... Big Cubic Inch only means more room in the cylinder head to put air and fuel.

6.4L -- I would still put turbos on it ... Big Cubic Inch only means more room in the cylinder head to put air and fuel.
I wouldnt put a turbo on a 6.4 they are very picky with boost alot of people are claiming there pistons are like glass one bad tune can equal a blown motor ripp just dynoed a 6.4 in a jk in 4wd it made 335 wheel hp
The engine is here! The engine is here!! OK I"m a little excited now. Balance of parts by end of week and then out to the shop!! Can't wait to un-crate the motor!
OK. Here's the schedule. Unless something changes, my truck goes to OK4WD on March 12th to start the hemi swap. It comes back to me on March 26th (my birthday by pure coincidence). OK4WD has a publicist coming to photo record the swap as it's the first 6.4L they are doing (They've done lots of 5.7Ls). The shop has a couple of go-pro cams on the bay where the work will be done and they will try to "time lapse" it. They would love to host the guys from JeepLab that are local or who care to make the trip so any and all JL members are free to stop by and say hi and inspect their work. OK4WD is on board with chronicling the swap on JL. Turns out there will be another 6.4L on site at the same time. An AEV built 6.4L truck is going to OK4WD for a Dyantrac RockPro 44 front axle upgrade. So they'll have a finished example of a 6.4L there for part of the time as a reference vehicle.
The motor and parts will be delivered next Monday 2/23 or Tuesday 2/24. I doubt the OK guys will be able to keep the motor in the crate until March. So I expect that they will un-crate it next week. I will get photos and feedback and put it all here.
I bet you feel like a kid waiting for Christmas. Can't wait to see some pictures!
Pickles, I'm going to have a spare 3.6L on my hands with roughly 50k miles on it. It has little value in the market since a person can buy a new 3.6 from Rubitrux or another shop's take out motor for around $2,500 with almost no miles on it. I'd love to tear it down and see what 25k miles with a supercharger looks like. Any thoughts? A JeepLab Skunkworks motor?
Prodigy has some sort of plan for building up the internals of a Pentastar. So far, they have shown pictures of forged pistons. If you're going to tear it down at some point, maybe it would be worthwhile to build it back up with whatever mods Prodigy comes up with? Then make a go-kart with it :)
I'm thinking find a 2012 or later used truck and make an absolutely bare bones light weight rig. I mean if it ain't pulling an oar it gets tossed overboard to save weight. Put the 3.6 together on a stand and make the truck custom front to back.
Got to see the motor today. Just a sneak peak in the crate at the dealership. It's on the way to the shop. Should un-crate it Tuesday.
Where's the pic? Are you crazy not posting a pic?
"I saw up heidi klums skirt today....but no pic to share with my friends...." (thats you) LOL
Gbauman, your threads are some of the best around, but for the love of god man, Please post a pic of that engine before it goes in. Ive been lurking this thread daily waiting for it.
Im fearful, that its going to go from the crate to the engine bay and we wont see it.
Too funny Yinkers! Fear not. The motor won't make it out of the crate without a pic.
And I respect all of my friends here on JeepLab. So if I get up Heidi Klum's skirt I'll immediately. . . .Oh, who am I kidding, there's no way I'm telling any of you.
Parts arrived at the shop today!

So did the motor.

Ohh lawdy that a sexy motor
Truck is in the shop! They plan to start today.
I talked to OK4wd a few days ago. I was trying to get a time when they thought they were halfway thru for some good photo ops. gbaumann,will you be there in the middle? or just to pick up?
Ross. PM me with your email address and I'll get you in the loop with Rin & Steve at OK4WD. If anyone else would like to they can PM me too. I'd prefer to not post my schedule here.
I got to see another 6.4L last night! It's there getting Dynatrac ProRock 44 front axle. Clearly there is someone out there with deeper pockets and less common sense then me (just kidding). When I saw the truck and added it all up I was both relieved and jealous in the same moment. I must say the Dynatrac ProRock is awesome looking! Do any members of the JL family run Dynatracs?
BTW the shop is going to try to get a Dynatrac ProGrip brake upgrade kit in during the conversion. If they are able to then I'll post pics and feedback on the brakes.
And so it begins:

The shop informed me that my automatic trans fluid is toasted at 47,000 miles most likely due to overheating. Not normal wear-and-tear. It appears that there's no metal shavings but a complete power flush and valve body service is now on the list for this build. This is my first real "sting" from the troubled transmission calibration caused by the supercharger. I suspect that there are only so many times you can downshift from 4th to 2nd at 75 mph before you overheat a modern automatic trans. If you can't calibrate in conjunction with factory torque management then don't mess around with it.
Body came off today.
I saw a pic on Instagram. I'll post soon. http://instagram.com/p/0S5L1DD0YO/
I'm surprised the transmission isn't more damaged-- going from 4th or 5th at 75mph to 2nd isn't a transmission friendly act. That usually ends up with a lot damage being done. How, long did it stay in second gear at these speeds before it shifted again? This is one of the reasons why I hate the devil's handmaiden called the automatic gearbox. I hope this time you get the transmission tuned better-- your new engine might do serious damage to if that happens. You could easily roach it.
The shop is surprised too. And I'm not convinced there isn't some damage. We will see. The NAG-1 is good automatic gearbox. It's in lots of Chrysler and Mercedes Benz performance vehicles.
Some progress pics.

Might as well POR-15 a lot of the undercarriage while it is that state. Super cheap insurance against corrosion.
Motor mounts in awaiting grinding/coating. Maybe I should see if they can use something special?

Not knowing whether or not it's safe to post I'm going out on a limb here (haha). Intake manifold is on the motor. Balance of engine prep underway.

For those not familiar with the AEV hemi conversion kit it comes with an AEV configured intake for the 6.4L hemi. It's basically the same intake but specifically made to work with the Chrysler/AEV engine control. The SRT 6.4L hemi intake uses two different length runners. It changes the runners at a certain RPM. The dual runner system improves the torque curve. The AEV intake keeps the dual runner system in tact when installed in the wrangler application. Not sure how other hemi conversions handle it.
Motor is in the chassis!

Does this conversion retain the original 5 speed gearbox?
If so, are you not going to just run into the same gear change issues you were having with the SC 3.6?
Yes and no. Yes, it retains the same gearbox. No, I shouldn't have the same shifting issues. The reason is that the conversion includes a new PCM (powertrain control module). The PCM includes the engine controller and transmission controller. Both units in the new PCM are programmed to work correctly with the 6.4l motor. The problem with the SC companies is that they, through DiabloSport, can only recalibrate the engine controller. They can't make changes to the transmission controller. So the new supercharged engine is mismatched with the automatic transmission.
Body is back on! I'm told they may start it tomorrow.

Oh so close! I'm going to stop by the shop tomorrow (time permitting) and hopefully get to hear it when they start it. Then, pick up on Friday.
