Help please 6nz74066

That engine can be flashed to 550@1850 with the stock hard parts as per serial number.

 

I'm curious what the op gets for fuel mpg average right now? I hope it's not 4.5mpg like those acert horror stories.

 

6nz is more similar to the e-models than you know. Parts are interchangeable.

 

Not really. The heat issue in the acert engines come from the high comp pistons and timing.

 

My 6nz was a 2 turbo motor made in 07, I do know it was one of the motors they were pay fines or some type of penalty on for emissions, but definitely 2 turbos and acert

 

Then it wasn't a 6NZ.

 

You win, I'm not going to waste my time, I know better.

 

You had a C-15. What serial number prefix it's obvious you are not sure.


The 6NZ was the first to be labeled a C-15. It was only offered as a single turbo and long out of production by 07. The MBN replaced it and was also a single turbo. It was known as the bridge motor. After the bridge motor is when the Acert twin turbo came out

 

I am sure you know more about CAT motors than I do, I am also sure I know more than you about which motor was in my truck.
