    1982 6.2L K5 :) Red block, 50 000 miles, and runs like a top! I've never heard a 6.2L sound as healthy as this one does, doesn't even have any blowby!

    Time for a set of 6.5L heads and a turbo kit ;)

    I'll post a sound clip after I drag it home tommorow, 700r4 is blown up, like usual, lol

    Plan on putting an NV4500 in to replace the slushbox ASAP. At the moment, it appears to be a bad torque converter causing the problem...

    My mistake, I know I had the 82 and it was red and I thought 83 was the same since they had the same controler setup too. But then again even the injectors for the 82 was differen from all the rest.
    :D

    So, as far as bolting a 6.5L turbo on goes -- Can I use my stock heads / injectors etc?

    I've got a complete 93 6.5L TD for parts sitting in the back yard :)

    Yeah, red block color and coarse thread injectors for '82 only. Some guys swear the '82 block is stronger casting too...

    Is there any reason why the stock 82 injectors wouldn't work with an 93 turbo? Or does a guy have to change the heads to 6.5 heads to bolt the turbo intake / exhaust manifolds on?

    Ok, so according to my reading, it looks like everything will bolt straight up less turbo to injector clearance issues.

    However, I was reading a post on thedieselpage.com that claimed the 82's injectors are shorter than the newer ones, so that might not even be a problem for me...

    We'll see how it goes, if it is just a matter of hooking up oil pressure and return lines, and getting exhaust done, I'll probally get this thing turboed before I ever hit the road with it, lol

    I've got a buddy who is big into these 6.xL diesels, and I'm sure he'd leap at the opportunity to help me turbo it, esspecially since he'll be getting the cash to buy all the parts, LOL

    The 82 injectors are coarse threads so they don't interchange with the rest.
    I believe the Van injectors are short, maybe the 82 ones too..

    I've learned alot at gm-diesel.com (search posts by hjacobson). The 82 block (599) has a higher mag(?) content than later years making it stronger, and the injectors were shorter with course threads. You can use newer heads on the 599 block to keep the injectors a common part.

    I thought the 599 was 93 not 82.
    I have a 599 block from an AMG hummer. :D
    And I know the 82 has higher magnesium content, but I thought also higher nickel which usually makes a good block.

    Yes, nickel is what I ment to say, sorry. I was under impression that the 82 was a 599 and used in the later years for a couple of years as well (hence your 92). I am going off of memeroy here, so I could be wrong. If I need to know for myself I would research at the other place, I'm still learning.

    Those 599 blocks can be punched out to make it a 6.5L, but I don't think I'm going to be going quite that deep into it yet, lol

    This engine has about 50 000 some miles on it (less actually), so if I can use my stock IP + injectors with the turbo, I'd think it'd be best to do that. The donor truck has like 250 000 miles on it, lol

    599 block was 92 and 93. I can't recall the casting number on the '82 block...only that it has higher nickel content making it stronger. The '82 block can't be bored to 6.5L bore size...but the 599 block can.

    That is one thing I like about the 6.2/6.5 and their Ricardo Comet V prechamber setup - they have a nice purr to them, rather than a loud obnoxious clatter (i.e. Cummins 4BT/6BT, 7.3L PowerStroke, etc.). :D
