does anyone know the specs on the turbos of the detroit diesels 8-71 and 6-71 i cannot find any info on them. i believe the 6 is smaller. either way there pretty big. any thoughts on using one on a 350?

I could be wrong but if I recall correctly the diesel turbos don't have an oil line. I'm not very knowledgeable with turbos though.

i have both sitting right outside. they have a line, maybe water. if they were internally lubed wouldnt that be even easier? or maybe if they were a chevy would spin em 2 fast for there lube 2 work. but i think its an oil line for sure

All DD turbos have oil in/out. The 6 cyl is smaller. The model depends on the engine and year. For a 350 you are better off with the 6 cyl turbo. It could work just fine or take forever to spool.

the turbo does seem really big, but i think it might work ok. a 6-71 is 71 cubes per cylinder and that equals out to 426 total, but the diesel only spins like 2500 versus 5000 or so for a chevy. of course the blower pushing out the exhaust would probably offset my theory, lol maybe i should just take the blower.we all kno the 6-71 blowers do a number on any chevy. but im trying to blow throught the tpi. i wonder what could be done to fuelie a 6-71 some kind of airbox and massive throttle body?

ok, so it is off a 6-71. Yes, your ci and rpm theory is correct. If I had a choice between the blower and turbo, I would take the turbo. That blower pushes a lot of hot air.
The turbo should be between 70 to 75mm comp. inducer. What is the turbine marking on it? .96 A/R?
Yes, it does appear to be really big......but the S400 you will read about being so great on a 350ci is the same size physically.

The part that you're leaving out is that they were 2 stroke diesels. Having a power stroke every 2 strokes rather than 4 means that you us almost twice as much air as a 4 stroke (almost, they're not as efficient with what they do get, which is the reason for the supercharger/scavenge pump on them).

i understand that. im sure a chevy will spin it fairly easily. though it will prolly have some major lag down low. i guess thats what a boost launch is for

i know of one guy who has one a 400cid small block, he races with it. he has N2o to spool it up. car makes like 1200 hp(300 something without the turbo). runs like 4's in the 1/8 mile.

^^^^ lol is all i have to say

You are forgetting that it is a 2 stroke motor, so its displacing that 426 once per revolution. We have a lot of 6-71 and 6-92 detroits in our fleet. The turbos will flow over 1400cfm. They are freakin huge. They are also antiquated technology.

For the blower to be of any use it needs to be a straight six. The V-6 blower would take some major rigging to bolt up to an intake. And yes you can inject a blower. Its been done and done. Search around.
