MBL turbo replacement c12

Go to eBay and search c-12 turbo, there's a Borg Warner unit for $824 with free shipping. I had an 03' MBN I replaced the turbo with a Detroit unit that bolted right up, did have to fab up supply and pressure lines but it gave me 35lbs of boost : )

 

Diesel Components in the Twin Cities carries Borg Warner turbos, they will even pre-drill for the oil lines to make the Detroit replacement a bolt on job. I currently have the 171702 on my C12 , but if I had it to do over again I would get the wastegated version. I dont thin I need all the extra cylinder pressure, as it isnt getting enough fuel to warrant any extra air. JMO

 

Unless you're willing to tune the ECM with an earlier C-12 file, you will have to bu a CAT turbo. Otherwise the electronic wastegate function will not work with any aftermarket turbo and you will have a fault code with a engine derate situation

If you're interested in tuning the ECM with a file that will allow an aftermarket turbo, PM as I can do this for you

 

Good luck and I won't say I told you so later

 

If you do nothing with the ECM than you are stuck buying the CATERPILLAR Reman turbo for your engine serial number. To do anything else you have to tune the ECM. PDI has a Stage 1 tune that will make it run with any C-15 550, but will require a turbo upgrade to match the extra fuel.

I can tweak the ECM with an earlier file C-12 to achieve roughly 470 to 500 Hp and than you can buy the turbo listed earlier in this thread without any problems

the choices are yours. Remember that a MBL is a bridge engine and responds very well to earlier file with both Hp and fuel mileage gains, because injection timing will be advanced. You also have catalytic converters in your mufflers that should be removed at some time in the future to help fuel mileage also
