Engine swap thoughts?

Found my new engine! BLUF: 6 cylinder quad-turbo diesel. 342 ft lbs torque at 1000rpm.

Man, that's four times more things to go wrong and four times the maintenance and emptiness of your wallet! You might as well supercharge the air before it hits the turbo's while you're at it.

But 332lb-ft at just 1000rpm and a consistent 560lbs-ft all the way up to 4400rpm. Oh, deary me.

BMW is unlikely to offer the engine in the United States so don’t hold your breath for EPA-rated fuel economy.

That's a crying shame.

Two stoke Detroit Diesels did have a turbo feeding a supercharger! 16V92 marine application has 4 turbo's feeding two blowers...of course they have the whole ocean to use as a heat sink to keep them cool.

I can't imagine how thick (or how many) that radiator would be and the amount of coolant need to circulate...

 

[bob91yj]

Liquid to liquid heat exchanger's are way more efficient than gas to liquid. 16V92 held maybe 10 gallons of coolant.

Our LAV's run a 6V53T Detroit with a single turbo feeding a supercharger. Sucks at low RPM but over 2000 it does pretty well for a 60 year old engine.

Good Lawd. That would make for a good KOH buggy powerplant

At the past SEMA Cummins was presenting the idea of crate engine conversion kits with the 6.7, 5.0 and a small inline 4. If that gets fleshed out and produced I would be interested whenever the 281 in my van craps out. I don't see how they could have a simple (and cheap) solution. New fuel lines, tank, PCM/ECM, then make sure that those talk to the ACM correctly. Seems like something you would have to sit down and go "alright I'm going to spend a bunch of money and it's going to be crazy, but I want to because I want to" not for a simple solution.

When I built my Beetle I was amazed at how even a minor change in a system would reverberate throughout the entire car in terms of things that had to be changed or modified.
