CAT 6NZ Turbo boost

Its a strong engine, may have had a headgasket under warranty if it spent its life in Toronto area. PM me the serial and I can check out the history, never know, I may have worked on it.

 

Peen.........I just tried to post a long answer to your inquiry, but lost it to the great world of the lost internet. I'm not going to retype it.

There are many options to what you can do. If I remember correctly I sent you a PM awhile back with my contact info.........give me a call and I'll explain the differences in your options, both with a CAT uprate, a PDI uprate or what I can do for you

My preference would be one of two PDI tunes with your cooling capacity of the T2000 for the best in fuel mileage and a slight power gain above a stock CAT 550 hp uprate.

 

i have a 5EK i think they are the same and its 30psi

 

Also run a 5EK. 28psi boost. Exhaust broke off the other day. Thought truck felt "peppier" but figured was just in my mind because of the noise. But boost gauge showed 31 psi. Dont like a loud truck, but i believe that makes a good endorsement for opening up the mufflers?

 

my boost is 35lb.

 

Got me a 03 6nz and it's my 1st Cat engine. Only thing is, I've heard e model cats make a slight growl when it asks for another gear. Some people have said to me about swapping the turbo with a cummins turbo on the e model. Since a 6nz is basically an upgraded e model, can that be done to the 6nz to make it do that growl just before u throw another gear?

 

No, there are good options for turbos without swapping to the cummins turbos they are thinking of.

Excess boost doesn't do anything but make heat, a 550 is right on the money at 26-28psi.

 

Hello, im from australia I run a 6nz and been doing some searching around as to how i can tickle this old bird up abit. Do you think you could send me the contact details of the customer in Aussie here to get some feedback on the tune you set him up with?
Much appreciated!
