Want to get some advice on a turboed 7.3 IDI - Diesel Forum

a shop is going to give me a price on a turboed 7.3 IDI. I now have an ATS turbo and was wondering what opinions TDS members have on getting this engine. Are these engines durable and how many trouble free miles do they deliever. Any opinions are certainly welcome.

Thanks

i would rather have the 6.9l with the 7.3 glow system. it is the same motor minus the big C word. will last twice as long and is less likely to have the "pits"

I would sleeve all 8 cylinders so it should not cavitate, right? Same engine, everything should bolt up?

In my opinion, the best way to go if sleeving would be to sleeve a 7.3 block to 6.9 bore diameter. This would eliminate cavitation and retain the big head bolts and other 7.3 goods.

I believe sleeves give you more wall thickness than stock even with a 7.3 l. Someone correct me if I am wrong.

Chum, buy a 6.9 long block, alot cheaper than a 7.3, have them add headstuds to the engine and there you go, a bullet proof combo, that you will have no worries with. Going with a 7.3 for an extra 20 cubes is not really worth the extra money. A properly set up 6.9 will run just as strong as any 7.3, plus you don't have to worry about sleeves, and all the other stuff. Add a 7.3 turbo IP, GP system and whatever else, but a 6.9 block is a known good. Scotty

I'd go with Scotty's suggestion as it will be cheaper to do.

Good call man!

Thanks, hoping I wasn't the only one thinking it. Fairly cheap to build/buy a 6.9. Add Headstuds and late 7.3 fuel system and man, you would have a sweet set up. Scotty
