    My 6.2 chevy Diesel GW

    Well, for those who followed our little 6.2 diesel in my J20 thread, my 1990 Gw Conversion is making head way. Got most of the body work done and paint stripped off. Also got the adaptor to a TH700 to a NP 229 today from Advanced Adaptors. Now just need to jack up the body and remove the frame & drive train to swap onto another frame, with the 6.2 and TH 700. All is on hold since the weather sucks in NE Ohio!

    Wooo Hooo!!

    I've been on the lookup for a cheap 6.2L.
    I am telling the world here and now, I WILL own a oil burner someday!

      Brian,

      I saw that you were on the 6.2 forum. You must be serious.

          What's up with the 6.2L anyhow? The 6.5L TD is a superior engine.

            I agree - if I were to go through all the trouble of a diesel swap, I'd definately install a 6.5 TD over that old 6.2 any day.

              6.2 are a dime a dozen, nothing really wrong with them. Plus, you won't have much room for a turbo, unless you eat some sheet metal! Plus more computer :o:o:o:o involved

                I've been doing some research, too. I've been restoring and driving military CUCV's for a couple years, I plan to put a 6.2 in a trail Cherokee project, and I am looking at a 6.5TD tow rig.
                The 6.5 is not a superior engine by any stretch of the imagination. They have a very bad habit of cracking the main webs in the blocks. Also, you'll have a failure prone electronic injector pump. UNLESS... you get the very early 6.5. The first year or two (93/94 I think) used the old 6.2 "599" block casting and a mechanical injection pump. The troubles started in 94 or 95 when they introduced an "upgraded" block that was prone to cracking. I am gonna stay away from those. They did eventually fix the problem with a new casting, but I'm not sure when.
                The pump mounted drivers on the electronic injection pump are prone to failure due to heat and vibration. Also, it is drive-by-wire, which kinda disturbs me. There are kits that are supposed to remedy the failure situation, but I'd much rather go mechanical.
                You're not gonna blow anybody's doors off with a 6.2. It'll turn the tires up on my CUCV Blazer pretty good, but I wouldn't consider one for heavy towing. It is, however, cheap and reliable. I get 20mpg in my CUCV Blazer. Parts are everywhere, and much less expensive than other diesels. Reman injectors are $40 ea and a reman pump is $400. Compare that to the prices for the others and you'll see why I like the lowly 6.2.

                  I was looking at a coworkers 1993 6.5T chevy truck that he is selling and I took a few pictures.

                  Look how big the turbo is on this engine. It would never fit a FSJ without some major modifications to the fender and the you would have to take the heater box out.



                  Here is another part that you must come up with for a diesel swap.



                  here is a pricey aftermarket fix - about $660 plus shipping made by Vanco. Looks like the same GM parts as my coworkers 6.5T truck.

                    you can get away with using your stock Jeep braking system. Just make sure you have both the gear driven and belt driven vacuum pumps. You have enough vacuum with one, but if a fan belt snaps, no brakes! I know it works, cause I have had a 6.2 in my J20 now for 2 years.

                      I was reading somewhere yesterday that when a fan belt brakes you still have more braking power with the hydroboost that you do with a vaccuum unit. They also say that the hydroboost system is far superior to the vaccuum booster - but here we go again throwing more money at the jeep.
                      If I ever do the conversion I figure I will just have to buy a parts vehicle. There is one in the paper for $700 with a bad 6.2 motor.

                        The 6.2 diesel is a very good all around engine if you know what to do with them, as well as the 6.5TD. I have had several in the past, my last 6.2 was in a '91 1 ton crewcab. It had been rebuilt balanced and the injection pump turned up 20% and advanced timing, with high flow injectors. It could win drag races and pull. I used it every day pulling 14,000lb. But with all the mods it got 8mpg with overdrive and 3.42's.

                            Not much! a 6.2 fits snug, need to do a lot of cutting away to fit the turbo, down pipe, and air cleaner.
