Volvo 780 w/ D-13

Not so sure about cheaper parts

 

new ISX is XPI (a kind of CRD). This system is more efficient, but less reliable and expencive, becouse it runs under very high pressure.

D13 fuel sustem is twin coil injector unit. Yep, more simple injectors like on D12A-C are better but not for new emission laws.

Both ISX and D13 got complicated aftertreatment system with DPF, EGR, SCR. And I'd say Volvo EGR+VGT unit is better.

Unfortunatly Euro-3 D13 and Euro-3 ISX will never be available in USA and EU, may be somewhere in Mid East ore SA

 

A guy I work with has a 2010 780? (big mid-roof) 500Cummins/13spd, he says he loves it,decent MPGs,only had 1 EGR code that took a Cummins dealer about 45 min to fix.He also said that the only thing he would change if he could would be the weight,its kinda heavy.

 

it is HPI engine w/o DEF. Will never be available in EU and US.... New is XPI with all emission stuff

 

I bypass my egr valves on d13 and the guy did it for $300

 

Volvo Mechanic told me D12 is much better than D13. If you have D12 he sad never, never change it for D13. Newer engine more problems. Good luck.
