One is belt or gear driven, and the other is exhaust driven. The turbos are easier to play with when it comes to choosing your ideal boost range. You need to synchronize them so that they compliment each other instead of fighting against each other. Each of them will make boost at specific...

Any idea what size studs the heads are set up to run? I'd opt for 7/16" ARP studs and fire ring the heads with the 0.010" thicker head gaskets cut to match the fire rings. Also, why the HX35 turbo? Why not run parellel twin turbos plus a supercharger? Optimize the engine for both low RPM Torque...

It would appear that the marine application has a higher HP rating, and comes in both supercharged AND turbo charged variants. I still haven't found a "where to buy" link yet, nor have I found out if a "crate" engine is available (e.g., complete engine with computer and harness set up for...

That is very interesting, I have converted the article to PDF and attached it. Really good information on the cylinder heads. But I need to look more to see if this block is publicly available, or if AM General is hold in on to it tightly for military use.... The best block is useless to us if...

I'm intrigued. What is this "optimizer" block? And what is it about this block that makes it superior to the J- Code block? My focus on the J block is due to availability more than anything, and the fact that the CUCV is already designed to use this block without modification, and it can be...

I did not know about those books. I will have to look into them. However, I still like the idea of getting a one stop shop for information set up here. Ever since I bought my XM211, this site head been my first stop for trusted information, an continues to be the first place I look (after the...

I have personally towed a K-5 with a K-5 on my trailer several times (my trailer is 1,681 lbs empty). I never trust a "bumper hitch" to tow anything, period. Personally, I would put a 2" receiver style, frame-mounted hitch on the M1009, a well-balanced car trailer, and tow the Jeep without...

Okay folks, I have been searching around SteelSoldiers as well as throughout the net regarding performance upgrades for this 6.2L diesel. I have found a few things here and there scattered around, but nothing that is devoted to turning the 6.2L into a power-house. I'd like to get a thread going...

I think there is a company building those heavy duty bumpers with the swing out carrier. If I remember right, the mount swings out and then down near the ground for mounting/dismounting the spare. I'd look through http://www.stacydavid.com (Gearz TV) for one of the Bronco builds, I think that's...

That's good to know. I was considering something like that but wasn't sure if it would work since I don't have a set of HMMWV wheels nearby to look at. As for the spacers in the rear, I can understand the need for them to mount the wheels face to face (spacer would actually sit slightly inside...

I know this thread is a few years old, but it is the only one I have found that is right on key for what I am searching for... running 37x12.50R16.5's on a GM dually. I am running a civvy '85 C30 Crew Cab with a M1009 6.2L in it. I am planning to build up the chassis (driving build) for putting...

I'm using an Android app called DriverDiary to log my expenses on my civvy 85 C30 Crew Cab 2wd Dually. The truck has the 6.2L out of a M1009 in it, 4.10 gears, TH400, and 235/80R16 tires. The vacuum pump on the truck seems to be out because it only shifts at 20 mph and 35 mph, and it doesn't...

About 15 years ago, there was a guy in central Illinois that lived out of his diesel van. He was running WVO in his van. He had a small tanker trailer, maybe 150-200 gallons, that he drug around with his van to all the restaurants and collected their discarded oil. Everything was processed on...

I was reading through the PDF that was attached to the above quote. My question is going to require an answer from someone with knowledge in chemistry, as well as electrolysis of water ( e.g. "Hydrogen on Demand" ). The PDF is very well written and easy to follow. I am still not convinced that...

Shipmate, What is a good mix for your M1008 and how do you test/verify the mix before running it? My civvy 85 C30 has a 6.2L from a M1009 in it, and I am looking into this reuse side of things. I have friends that either own or manage quick lubes, fast food restaurants, and trucking companies. I...

I think there are actually tax incentives for making your own biodiesel. To my knowledge, no permits are required for biodiesel in Ohio or Illinois, nor federally. However, if you are making ethanol at home, you are supposed to obtain a permit from the BATFE for you ethanol still and there are...

Outstanding. It is getting harder to come by the 700R4's set up for the diesel... I can find them out of cars all day long, but the heavier duty ones with the right torque converter and the right shift points is getting to be a PITA to locate. And if memory serves me correctly, the 4L80E doesn't...

I know its been referenced somewhere on this site, but can you refresh our memories as to what aftermarket module and harness is required for the 4L80E and where we could acquire such a contraption? I am considering a 4L80E for my XM211.

I have the corporate 14FF in my civvy 85 with the 4.10s in it now. I also have a corporate 14FF from a 2002 GMC 2500HD with low miles and 3.73s sitting in the barn, left over from the axle upgrades I did on my 2000 Silverado half ton last year (package deals come in handy sometimes). I now have...

I have a 2wd civvy dually that runs 4.10s and is running the TH400 behind the 6.2L J code. Tires are 245/80R16s. She cruises comfortably at 62 MPH down the highway, but I can hear the RPMs are up over 2500, and fuel consumption is pathetic (7 MPG). I want to get that down around the 1800-1850...
