Hey guys,
Was hoping someone can pin down for me the difference between different VM Motori Motors, mainly:

R428
  • 2001–2007 Chrysler Voyager (Automatic transmission) (power: 150 hp (110 kW); torque: 251 lb·ft(360 Nm))
  • 2001–2004 Jeep Cherokee/Liberty (power: 150 hp (110 kW); torque: 251 lb·ft(360 Nm)). Only in Europe
  • Evolution of R428 DOHC with 1800 bar common rail injection system and piezoelectric injectors

    2005–2006 Jeep Liberty (power: 160 hp (120 kW); torque: 295 lb·ft(400 Nm))
  • 2008–2010 (mod. RA 428 DOHC) Jeep Liberty (power: 177 hp (130 kW); torque: 302/339 lb·ft(410/460 Nm))
  • 2004–present BMC Megastar (power: 127 hp (95 kW); torque: 184 lb·ft(250 Nm))
  • 2007–2010 (mod. RA 428 DOHC) Dodge Nitro (power: 177 hp (130 kW); torque: 302/339 lb·ft(410/460 Nm))
  • 2007–2010 (mod. RA 428 DOHC) Jeep Wrangler (power: 177 hp (130 kW); torque: Manual transmission: 302 lb·ft or 410 N·m automatic transmission: 339 lb·ft or 460 N·m))
  • 2008–2011 (mod. RA 428 DOHC) Chrysler Grand Voyager (Automatic transmission) power: 163 hp (120 kW); torque: 295 lb·ft or 400 N·m))
  • 2012-2013 (mod R 428 DOHC) Chevrolet Colorado & Holden Colorado & Nova S10(Brazil) (Manual and Automatic) 180HP Torque 470Nm
  • 2017–present Maxus T60 (Automatic & Manual transmission) (power: 150 hp (110 kW); torque: 251 lb·ft(360 Nm))
A428
  • 2010–2012 Jeep Cherokee (power: 200 PS (147 kW); torque: Manual transmission: 302 lb·ft or 410 N·m automatic transmission: 339 lb·ft or 460 N·m))
  • 2010–present Jeep Wrangler (power: 200 PS (147 kW); torque: Manual transmission: 302 lb·ft or 410 N·m automatic transmission: 339 lb·ft or 460 N·m))
  • 2011–2013 Chrysler Grand Voyager/Lancia Voyager (power: 163 PS (120 kW); torque: 360 N·m)
  • 2013–present Chrysler Grand Voyager/Lancia Voyager (power: 178 PS (131 kW); torque: 360 N·m)
  • 2013 Holden Colorado, Holden Colorado 7 (power 180HP); 470Nm (Updated November 2013)
  • 2014–present General Motors, Holden Colorado, Colorado & Holden Colorado & Nova S10(Brazil) (power:200HP Torque:500Nm)
I mean, the two that I am looking closest at are the difference between the 110kw/360nm T60 and the 149kw/500nm Colorado engines.
I mean, Wikipedia says that the A428 is simply:
Evolution of R428 DOHC with 1800 bar common rail injection system and piezoelectric injectors
So, does that mean that you could swap the Common Rail System and Injectors from a Colorado across into a T60 and get the performance gains that the Colorado has?

Why would you bother mate, really , a bit like flogging a dead horse ;)

I dunno, every gain is a good one is it not?
Most of the Jap diesels started to go down the toilet when they tried to squeeze more out of the same or less cubic inches. Toyota have gone from reliable to questionable and Nissan don't bother anymore.

I registered just to say that this would be useful info if someone had it.
to know the differences between the new A428 engine and the older RA428 engine.
as in, could the newer engine short motor be used to repair an older RA428 engine.
can a colorado engine (that cost $2.5k on ebay and trading sites, running (i believe to be A428 engines)) be used to fix a Jeep Wrangler 07-09 (older RA428 engine( that are for sale on ebay and trading pages for $5.5k running.))

substantial saving on price.
I'm sure the later inlet has a square port at one end vs the older inlet having the triangular port, but can the older rail and pump be used on the newer intake? or even with minor modification.
same injector? same exhaust ports? same mounting points for accessories? (power steering, air con, alt)

has anyone actually had the 2 engines on 2 engine stands, side by side, that can confirm or deny differences???
I'm on a spare parts site that lists most parts as being ok for 07-18 CRD's.... but it is the UK.


anyway, slightly old post revived...
