Swapping 12.7 turbo to an 11.1

I have a used turbo off my 12.7 S60.

Friend has an 11.1 S60 farm truck with a blown turbo.

Both are Garret.

Can he use it - ? My mechanic thinks it spins faster with more pressure and would risk engine damage.

 

@jamespmack might know. Does the 11.1 use K31?

 

Won't see why it wouldn't work. If anything the A/R on the 12.7 might be a tad larger giving a tad more lag and less drive pressure

 

With out part numbers you peeing in the wind. My guess is it will run, but worse than before.

 

A reman original garret can be had for $526 on sale currently at M&D distributors. A new B&W can’t be much more. Dave’s Turbo is a good source. I found the specs, courtesy Jegs. Obviously the smaller ones for the 11.1

 

Part# for 12.7- 171702. 11.1- 169012. Pretty sure that’s right.

 

Those #s might be for non wastegated turbos. I think wastegated ends in 1. Either way make sure, depending on what he wants.

 

I replaced my 12.7 with a Borg Warner and it was a 171702.

Buddies truck is a ‘92 White/Volvo with the 11.1 in it. He loads the poor thing to 100k gross with beans and grain and hauls 5 miles to town.

He’s keen on saving a buck, mechanic is nervous about the idea.

If it were me, obviously - new correct turbo and go on. He, well - farmers, you know.

 

What does the K31 refer to?

 

If thats the case. Yes yours will work. Its going to preform poorly compaired to what came off. Highly doubt it will lead to a over boost situation.

I can dig out my books when I get home.
