That engine is a unique and complex little bugger. The transmission is not the same as the one in the GM Duramax trucks. Its the industrial version with a completely different tune and stand alone TCM. The bellhousing is an SAE 3, the output flange is a 1480 series and the engine is a rear geartrain which devours the firewall space.
Its not going to make 300+ HP cheaply or reliably. The engine is stock rated MAX at 170 hp / 420 Tq and that is with the Cummins provided tune. There are NO tuners available yet except for the Bosch ECM and Narwhal ECM which are both several thousand dollars and require and entirely custom ground up fuel timining map. Most all of these engines are factory preset at 333 tq and 140 HP, which granted is way more than most 4bts produce. The ad saying that its that awesome is quite misleading. Yes, it can be done... is it affordable.. no. There is a guy in CO that takes the front gear train engines and installs Dodge 5.9 injection parts and then custom flashes the Dodge 5.9 ECM... Bare bones cheap motors are falling in over $15,000 though.
I'm installing the ISB170 into my Carryall project currently. Its a pain. I haven't even heard mine fire yet as I've been doing a million other things. The price for that one is quite fair though. If you CAN get your hands on it, buy it only if the ECM and COMPLETE harness with starter, and all accesories are there. Any random small part for it will cost you an arm and a leg. Its all European based and was built in England and does NOT meet US emissions standards. The fact that there are not more of these engines is because they are mostly in Fedex trucks and those trucks are supposed to be destroyed when the truck meets its demise. On occasion one slips through the cracks and ends up in a wrecking yard or some Cummins dealers ended up with spares in crates from the original builds of these Workhorse Vans.
I've got hours upon hours invested into reading and understanding the wiring harness, engine controls, features, switches, internal errors, fuel system requirements etc on mine. Hoping to hear it fire in a few weeks though.
