I suspect a stock M52 would be really good in a 2002. I'll be following your build, I'm intrigued to see how it works out. Change of plans! an hour after I posted here I found an M57 that I could not pass on. Yesterday was an 11 hour trip to go and pick it up So I guess I will be using the engine I wanted in the first place :) Link to comment Share on other sites More sharing options...

I am not entirely familiar with the M57, what sort of power and torque does it produce? I see a turbo so it must be turbocharged. Link to comment Share on other sites More sharing options...
coheed Posted March 4 Share Posted March 4 This is such a crazy cool build. Very excited to see a Comanche with a M57. I know the Patrol guys in the southern hemisphere love swapping them in because of the torque and they sound awesome. You're gonna have one hell of a truck once it's done Link to comment Share on other sites More sharing options...

The that does tuning for me tells me I can go 260hp 600nm with it stock. Link to comment Share on other sites More sharing options...

colthrax Posted March 12 Author Share Posted March 12 Got to try the rear suspension last saturday, and it works amazing. and the day after that the engine is on it's way out Link to comment Share on other sites More sharing options...
colthrax Posted March 21 Author Share Posted March 21 The engine was bigger then I thought :o The adapter for the engine to the AW4 was delayed, so now I am just waiting. Hopefully it comes next week. Link to comment Share on other sites More sharing options...
colthrax Posted April 8 Author Share Posted April 8 It turns out there was a lot more involved than I initially thought. I need to create an alternator relocation bracket. The BMW alternator is too big and interferes with the steering box, so I'll check if the old 4.0 generator can fit. I've completed one engine mount, but I ran out of gas and couldn't continue. The engine is mounted to the AW4 transmission, and the flexplate is bolted to the torque converter. I also purchased the "nifty shifter" from Nick. For now, I'll have to manually shift the transmission until I get around to making a mount to fit the 4.0 TPS sensor with the electric gas pedal.

colthrax Posted April 14 Author Share Posted April 14 Mounted a much smaller alternator, I really hope it gives enough power for everything. Otherwise I will have to redo that in the future. Pumped out the fuel from the fueltank, mounted a diesel filter and help pump as it needs 3 fuel pumps for some reason . Started with the wire harness.

colthrax Posted April 19 Author Share Posted April 19 Finally got the engine started, after chasing a no start problem for 2 days. Turns out I had not pushed the common rail pressure relief valve connector all the way in Found a 2.5 diesel radiator, so now I don't need to route the cooling hoses in a stupid way. Its damn hard getting the 2.5 inch intercooler pipes to fit between the lights and the body 150C33E3-EC8C-4ED6-95E9-5BA721AFFA94.mp4 Link to comment Share on other sites More sharing options...

Comanche SS Posted April 22 Share Posted April 22 Looking good! I had at one point planned and even swung in an AUDI V8 into my IFS MJ, but eventually went a different route. @Pete M This build seems more applicable in the Epic section, no?

colthrax Posted April 25 Author Share Posted April 25 Was out test driving it today, everything actually seems fine except blowing one intercooler hose. Not finished hooking up the nifty shifter, and my NSS is bad so I only had 2th and 3rd gear. It was only smoking that much because I was not getting boost pressure from standing still there revving BC442C84-09D4-42DE-9DCD-673B8E8D9AA6.mp4 A236C2C0-A298-4ADD-9D51-16CE75500D0D.mp4 Link to comment Share on other sites More sharing options...

pizzaman09 Posted April 27 Share Posted April 27 I am so excited to see build is going well! You are going to have some serious torque. Out of curiosity what displacement is this engine? Is it a cast iron block? Link to comment Share on other sites More sharing options...

Thank you! :) I won't be pushing the eninge too much for now, but will stay at around 270-300hp so that will be 705nm or 520ft/lbs. But compared to the 4.0 I notice a huge difference in acceleration atleast 3.0 liter (2,993 cc - 182.6 cu in) It's the cast iron one, the newer ones have a bigger bellhousing so they are harder to fit to the AW4.

colthrax Posted May 10 Author Share Posted May 10 While playing around with the gearbox, I decided I might try and tap into the output shaft speed sensor instead of converting the one in the transfer case to an electric one. Seems to work alright, just having some weird problem I think it is getting an extra pulse sometimes. Might try to clean that up with the arduino I am using for shifting.

colthrax Posted May 11 Author Share Posted May 11 I am jumping around and doing things everywhere on the car now it feels like, but decided to fix a small problem with the shifter. I removed the niftyshifter for now and just controlling it with my arduino. The niftyshifter works, but I am just having issues with the way I want to controll it as I want it sequentially shifted and it was easier to just do the controller myself for that. I am using an arduino uno r4 and a 4 relay module for it. IMG_5773.mp4 Link to comment Share on other sites More sharing options...
