New Cummins 5.9L engine in my Breakaway
Sorry guys and Gals, I have had a LONG repair on my Breakaway. Not much time to spend here on the Barthmobile site.

The engine in my Breakaway had 330000 miles on it and was getting tired, further I tried to bump the power abit. I did an inframe overhaul and that turned out to be disastrous! Probably if I had left it alone it would have gone to at least 500,000 miles but was getting boring!

I now have installed a NEW Cummins 350+ HP 5.9L engine in and it is GREAT. Finally FUN to drive! GREAT power and virtually no smoke,a little bit off the line but I am working on getting that lower.

I am working now on a full write up with pictures of my overhaul and subsequent instillation of the new engine. This may take a few days but I am not that fast getting pictures and write up done.

More later

Hi, now that it's been 4 years will you share some photos of the build? Smiler

It is a 5.9 12 valve correct?
I am curios what power mods you made to bring it to 375 HP+?
Compound turbos maybe? What kind of boost are you running?

Thanks!
