Deciding which turbo ser 60

I'd start by calling the place you intend on taking your truck to get the ECM tuned. They should be able to make a recommendation on if your stock turbo would work or if you need to jump up in size. They might even be able to give your a recommended turbo number for the horsepower you're jumping to. If they give you a part number, you can Google it and get an idea of the price you'd pay if you miss out on your current deal. If you're sure you're going to tune the ECM, I'd hold off till you have more info.

 

I think you should get the 70mm compressor wheel turbo and keep it in the truck with you, until you decide to get the ecm tuned. You can put it on now, but it may be a little sluggish without the tune.

 

The tune will most likely add between 75 to 100 hp on your 11.1, so going with the Borg w/ the 70mm 450hp might benefit you the most. Rebel will chime in soon and give you his expert opinion.

 

I would look into Borg warner but not the turbos they recommend for the 12.7. 171702 is 75/100 compressor and 88/96 turbine. It's large even for a 12.7.


I would look into the 92mm turbine wheel and either the 67.7 compressor or 71. The 67 compressor is stock billet and comes with the race cover.

 

The b/w 167735 is a non waste gated turbo.

 

Here is a good reference for BW turbos for the Series 60. Scroll down the link and you can find various BW models for different engines, hp ratings, etc.
