I had a bit of a far off dream to modify an 8v92 and have some strategies for cooling before putting one into my MC5 (I have some potential 'racing solution' to apply to the radiators etc). I was going to also tackle the 92 series diabolically slow combustion which would also have a knock on impact on how much heat it rejects to coolant. But right now my 8v71 is fine and I was continuing to research into this and was even going to buy an old knackered engine which I would rebuild myself over the years. Based on Scotts experience and what you say - are the silver series 8v92s inherently weak?
I'd like to know. I was planning a twin turbo set up.

Im used to CAT C15s , DT466s and Maxxforce 13s. MAN 12.4 litres, in which you can ramp up the power and the longevity on something with a relatively light bus duty cycle and the durability barely goes down. I had assumed this was also the case on the 8v92s. Was that a bad assumption?

The problem is that over the years about all the 8v92 engines have been 1/2 @$# rebuilt several times,I get 8v92's in the shop where the last guy left off the crank web supports because they were in his way or he forgot the supports,shop leave off the head supports all the time

Ok, had some concerts today back in the saddle. Read through all your posts:

1. Don, a lot of fire truck apparatuses get 500hp 8v92's and don't have issues with them...same for boat/marine use. If you keep it cool, it will last. Maybe not as long as a 400hp unit but I'm not looking to get a million miles. But I do think your right, it's important to know the history of your engine and I don't know mine.

2. I really do want to talk to Brian if someone has a phone number for him. He did chronicle his military install and I'd love to chat.

3. The fire engine 8v92 sounds great but wouldn't I be in the same boat of it not being set up for a bus? Can someone correct me? I'll be in Ocala tomorrow and would love to look at this engine on Monday if you guys think I could make a fire engine motor work.

4. American Fleet quoted me $18,500 for a rebuilt unit plus shipping and core charge.

5. Leid diesel, so I actually
Have a buddy that lives in Wisconsin that knows the leid family well. They are Mennonite from what I understand and know their two strokes better than anyone. I'll call them on Monday.

Ok, then I'll continue on my dream. I have a good ten years to re -engineer and build this thing methodically and an almost limitless budget (within reason). Would love to talk to you on the phone and pick your brain some day Cliff.
In the meantime my 8v71 seems to be in good shape.

Scott the fire truck engine is the better choice it will have all the accessory drives plus it will have the double cooler for the automatic and a drive for the belt driven alternator a +pretty straight forward replacement just a few minor changes try for a DDEC lll or iV they are better engines,people dread the DDEC engines but they are easier to work on you don't have the rack,linkage and governor to contend with lol just ground wires

good luck

Thumbs up for Leid diesel. They're located in Newville, Pa. Close to Carlisle. Very reasonable labor rates also. They are the ones that rebuilt and turboed our 4104. Great people.

The 8V82 that I took out of my bus is at Ray Cox place in Atlanta Ga. The engine had 135000 total miles and ran great. When I did an oil sample and found water in the oil it gave me a reason to change to the series 50. The engine didn't use any oil and the leek was very small, more than likely an injector tube.
I don't know what Ray would want for the engine but it would be a drop in because it came out of a 102C3. It is a DD2 engine.

Thought came to mind that there are still many early Wanderinglodges and Prevost conversions that have the 8V92 rated at 450 and 475.. Being in a motorhome they never see the mileage or hard use that a bus would receive .. Many are are sitting on old tires and can be had for small money..>>>Dan

Thanks guys. For some reason I thought leid was in Wisconsin but I believe you.

1. Thanks cliff, I'm looking at a fire truck motor hopefully tomorrow if I can get Dale to call me back. We made it to Ocala.

2. Jack, do you have a phone number for Ray? I can replace the injector tube if that's all that's wrong with the motor. Can you reliably confirm the actual mileage on that engine?

3. I'm definitely interested in a low mileage unit but the drama of removing it from a chassis and then trying to tow the chassis to a scrap yard is more drama than I think I'm down for.

Be careful of firetruck engines they can have low miles and hundreds of hours idling or pumping.

He can plug in and check the hours vs the miles lol DDEC's don't lie to you ( not yet)

Scott & Heather · January 26, 2020, 09:23:36 PM

Yep. I'm taking my laptop and Nexiq with me. Lol. It will tell me da truth for sure.

blue_goose · January 27, 2020, 05:45:16 AM

I am sure that is all the miles on the engine, not sure Ray still has it or not. You would have to do a pressure test on the engine to be sure where the water came from. Ray number home 7709279894 cell 4043927059

Jack,

1. Ray completely dismantled that engine and it's currently in pieces so that's a no go.

2. leid diesel can get me a reman for $15,000 plus shipping plus core but are six weeks out. I don't have six weeks unfortunately.

3. Can't get call back from Dale with the fire truck engine.

This is a silver 8v92 ddec II that id like to buy. Was a school demonstration engine. Supposedly never had a load. Please look at these photos and tell me if you guys think I can make this work. It's my last shot. I've been trying all week to find a decent takeout. Please tell me I can make this work. He will ship it for free and I think he might take $6000 for it:
