Links for 6nz swap in 3406 Peterbilt?

Your not the only one that has this opinion, I can't remember his name but he was from either North or South Carolina and was on here often a few years back and also stated the 6NZ had head issues.
He also sold Petes and KW's on Youtube, nice clean units.

 

You can run a ELD in any truck with an electronic engine. And find a 379 pete that's a 94 to 99 and it will already have an electronic engine and satisfy your no ELD desires.
And if you get an older truck with a mechanical B model cat going electronic is not a big deal if thats what you want to do. Everything is a bolt in ,its just the wiring and thats not hard with a compleat kit from kustom truck or mak industries.

 

Have you ever compared a 2WS or other earlier blocks to a 6nz block? The 2ws has much ruggeder/wider/ thicker main bearing caps. First time i seen a 6nz block i couldnt beleive how weak they looked compared to the older blocks.

 

Yes. Hence the sculptured block coment.

 

My 1995 5EK 3406 just needed a 1999 flash file to work with a EOBR.
If i remember It was no charge at the cat dealer, but I was having other work done at the time.

 

I was digging back on some old threads and found this info from mr Haney explaining the history of the 3406e up to the c16. I thought it was interesting and may help with questions you have...

Here's a history lesson the first 3406E Model engines had a Cubic Inch displacement of 890CI or 14.6Liters in size this engine was introduced in 1994. The 964 CI or 15.8Liter 3406E Model engine was introduced in the last part of 1998. The 14.6L engine had a power range from 335 Hp to 550 Hp. The 15.8L engine was from 575 Hp to 600 Hp. In 1999 CATchanged the electronics system to the newer design that's used in the C-15and C-16, but still called them 3406EModels, because they didn't changethe block structure or the way it sealsat the gaskets. In 2000 CAT made quite a few changes to the block structure for better sealing of gaskets, with these changes they changed the name of the engine to reflect the liter size, hence the names C-15 and C-16. These engines were built until Sept. 2002 when the new emission standards came into effect. The C-16 was dropped at this time and the C-15 continued until the first C15 Acert was released to the public in 2004. The C-16 is a great engine and can buildtremendous amounts of torque whenmodified for power, but they all havethe same issues...........liner protrusion and liners settling if the protrusionisn't correct. Either of these motorscan be modified for huge amounts of horsepower with great results.........the C-16 will build a considerable difference in torque in a modified version than a C-15, but the horsepower seems to be very close to each other.

 

You don't even have to have electronic engine to run E-Log. Just a tablet or laptop if per requirement from company.

 

Shows your knowledge of these cat engines, an acert that is built right will outlast all the previous generations and do it more reliably at higher power.
