Twin turbo options

[1badve239]

Hi guys, I currently have a single hx40 turbo and would like to upgrade to compound or twin, (I forgot the correct term) I would like to get a turbo from the junkyard off of like a semi or farm tractor etc. what should i look for? I'm upgrading too a 14mm head, electric lift pump, cam, valve springs, studs and big injectors. I would like to get started on looking for a turbo because I believe this will take some time. Thank you for any input

The bottom turbo in my setup is a 75mm s400, part number 171702. I've read that it comes stock on 11.1L Detroit engines.

My vote goes to an HT3B. An S475 would be ok also, I just like the commonized HT3B

what does a ht3b come off of?

I believe correct me if im wrong guys the ht3bs can be found on the N14 cummins at least the two dump trucks we have have that turbo on them hope that helps

1badve, its compound. 1 turbo compounds the next turbo.

Twins are 2 of the same, like real twins.

I have an HT60 that I pulled off an N14, I thought the HT3B's were off the older 855's?

Though an HT60 will work fine as well.

I was looking at an HT3B today on an older 855. It came out of an '86 Diamond Reo. The exhaust housing looks huge! My buddy also had a HT4B sitting in the parts trailer. That looked waaaaayyyy too big.

that HT60 he is talkin sbout gives off a REALLY good whistle lol but thr dang thing on the exhaust side has to be close to a foot across!!!!! buut it spools very nice:)

I guess its just an upgrade for the Detroit, I thought it was stock on some.

Lots of cool stuff there for sure!
I actually got mine from http://www.turbosupply.net to the tune of $552.
The fleetsource link just had a better description. Turbosupply is a good place to get stock unmodified turbos if you know the part numbers, no special stuff.
