detroit diesel 12.7 vs 14L

Not today!

 

Wish we had non-EGR engines in 2007 trucks! Lucky Aussie's!

 

I have 07 14l, set 515, 358 gears,10 spd,,,,will not do over 5.7 no matter speed or weight

 

3 digits 99.9

 

Nice, so my 3.58 rears are junk too?

 

there can be many problems. ill tell u one forsure, egr lol illegal to talk about but none of ours trucks have it. there can be many things like a leak in the air to air. how does the truck run? many people have had similar problems getting the fuel milage same specs. search this forum youll find answers.

 

I have 3.58s and they are just fine pulling legal weight loads.

 

I have a 2008 kenworth t2000 with the isx, I am just tired of the cost to keep with the repairs on this engine, can a 1998 12.7 be swapped in place of the isx ? Thanks for the input.

 

no, it is illegal to alter the emissions system, and illegal for the shop to do it, so finding a shop to do it would be hard.

that truck has to be 08 or newer emission compliant. and if it wasnt illegal...to make that swap would be pretty expensive, changing electronics, motor mounts, ect...or even a swap to a compliant 12.7,14L, or acert

thats why gliders are legal,they never had an emissions system to alter.

 

Looking at a 2004 Freightliner Columbia with a Detroit 12.7. Truck has 1m miles and the asking price is 13500. Does the 2004 have the EGR?
