K31 Turbo Swap 550hp Detroit 60 Replacement Upgrade Performance Diesel Boost Semi Truck from 171702

This video is about swapping turbos on the Detroit 60 series engine 12.7 liter. The current power is 550HP 1950 torque. The 171702 turbo is running on a million mile engine and spools up kinda slow, it is lacking low end but great top end. This is an attempt to setup a better power band and mpg with the Borg Warner K31 turbo. Straight forward details as I explain how to swap out Turbos. With no experience, this video will help you get the job done on your own.

I have my 14 liters with the K31 & my boost I get 37 to 40 in a good hill 1850 torque winter time

You don't have to loosen all those bolts to rotate the cold side of the turbo, just that big ass clamp!

Hi question,i have a 14l Detroit switching from the vgt to a k31.which oil line kit do i need or what's the inlet & outlet sizes

[@vroor32]

I upgraded my 500hp 12.7L stock turbo (k31?) To 171702 mated to the PDI 1-piece "ceramic coated" exhaust manifold. Theres no noise at idle and my egt stays at 700-800⁰ flat ground. I never let egt go above 1100⁰ on hill climb. So far 2 years without a tune, and i dont think im missing out on anything. My fuel economy is at 7mpg IFTA in the North East traffic & PA mountains. Also, my boost gauge maxes out at 32-33psi ... which is correct coz Detroit 12.7 is set to 16hp/1psi ... so 16x32 = 512hp and 16x33 = 528hp .... maybe previous owner had the ecm tuned and i have no idea 😂

I got a ddec4 12.7 tuned to 525 with stock gt42 13spd lp22.5 and 3.55s will the k31 be to big for mine?

[@marlonmontenegrin6102]

What are the torque specs ?

[@armin041590]

I have a borg warner with wastegate and with egr delete and reprogrammed 500 hp. 14l detroit. Should i get better mog or should i tune it down 455 hp for hetter mpg's

[@killnconquer2645]

I got a tune to 500 on my 12.7 but I have stock turbo which is undersized what do you recommend k31 or 171702

[@thodge4375]

Since you swapped the 171702 hows the k31 working for you with 550 horsepower. are you getting the power & the fuel mileage you need & was the k31 a better choice for the horsepower you got now. & also what is your boost pressure looking like? & do you miss the 171702. From having used these two different turbos one at 600hp & one at 550hp which is the better setup

Hello I have a k31 don’t boost more that 21 psi at low end is ok but 9and 10 Jesus no balls . Wat u thing about a boost elbow u think it will work . Any ideas

[@dominicilloniz3530]

[@user-vn7gw8dw5f]

[@ItsNicolasNotNic]

What torque kit are you using?

[@kylebowman4419]

So did you stay at 550/1850 with the k31 on? Can the k31 handle 550/1850?
