I have a 1998 C3500 with the 6.5L detroit diesel and the engine is officially gone off to a better place... I was wondering if it was possible to put a 1992 6.2L in this vehicle... I realize mechanically they will line up but I wonder what sort of electronic issues I am going to run into?

 

My 6.5 died at 150K and I replaced it with the 6.2. Runs great and no problems. As matter of fact it runs better than the 6.5 I had in it or any 6.5 I have ever rode in. Used the 6.5 electronics on the 6.2 with no problem.

 

I figured it should all work....just wasn't positive and figured I would check before I went through the hassle of swapping the engine! Thanks!

 

will work, swap everything off the 6.5 onto the 6.2 including IP. Only thing I'm not sure about is if injectors are interchangable, and if not, are the lines.

And its not a detroit

 

yeah it will work fine. and to second what fastcr said your 6.5 is not detroit. Detroit Diesel helped Gm to desighn the 6.2 but thats it. same thing happened to the duramax. Isuzu helped GM deighn the LB7 but after that they didnt help anymore. your 6.5 is a detroit diesel as much as a LMM duramax is an Isuzu.

 

Swap everything over to you 6.2 from your 6.5. The lines will work, and i believe your injectors will too. The manifolds will all bolt right up. So basically you will be taking everything off of your 6.5 down to the block and heads, and do the same with the 6.2, and then put all the stuff off the 6.5 on the 6.2. Cheaper way of getting a diesel chevy back on the road. I happened to find a deal on a 6.5 with 90k on it. But its all about the deal you get....

 

depends on vintage of the 6.2, if a early "red block" 6.2 injectors won't swap as those are coarse thread, also I don't believe 6.2 injectors will flow enough for best turbo feeding, needs to be 6.5 injectors for max return on the project.

Least expensive way to get on back of road is to buy a complete vehicle, and part out the stuff you don't need, you can get complete vehicle some time cheaper than what some folks want for just an engine.
