iveco 5.9l 6cyl turbo

[ivecowaggy]

I picked up an 84 GW with a 5.9l straight 6 turbo diesel made by Iveco, the PO bought it from the guy who made the swap, it has the GW 727 trans with a 229 backing it up, and I'm extremely happy with it as I nail down all the little quirks it has but still finding it very hard to source parts and information on this goofy engine. Since I bought it a few months back I have replaced batteries with matching ones, adapted the A/C to blow heat since they did not put a condenser in it. I've also added 3 inchs of lift and a new to me drive shaft in the back. And most recently a new GM 1 wire alternator. With all that being said I have a few questions to ask, one being has anyone ever added a 12v flame preheater plug to aid with cold starts? This would only apply to those WITHOUT glow plugs? Also how happy is everyone with the stock trans if any of you have kept the 3sp? Any input or advice would be great, I'm new to diesels but I know some. Thanks in advance and I hope you like this strange swap.

I heard some of the Iveco trucks used a Deutz air-cooled diesel, that's not what you have, is it?

One of the favorite things about my 4bt conversion was the Th475 GM transmission instead of the 727. I know Torqueflights have a good reputation, but the GM transmissions seems to hook up much better. It could all be in the torque converter. My 727 always seemed slippy.

Diesels don't like high rpms. Cruise it at 1800 or so. That typically means an overdrive trans. Are you sure about the GW 727 and that the previous owner didn't put in a Dodge version?

[ivecowaggy]

Its definitely the gw727, not an overdrive, and no its not an air cooled, liquid cooled iveco 4060.25 is the engine model it is supposed to make about 120hp and I haven't found a torque spec. From what I could find about this engine is that they are super reliable other than the water pumps. Nothing is electronic on it so it must have been a somewhat easy swap... other than the size of the engine related to the size on the engine bay.

These are almost as common as 6bts over here in europe,certainly southern EU ,good motor and some say it's the original 6bt design,should be able for much more power to

IVECO=FIAT

The engine is out of a euro cargo not Iveco daily. And yes Iveco is/was partnered with fiat, and vortec 350 I wish they were common on this side of the pond, parts and knowledge are hard to find about these things.

iveco is here in europe popular, specialy the light trucks like daily.

Whats involved adapting one of these to an American/US transmission?

[ivecowaggy]

To be honest it just looks like an adapter plate, not sure what's on the crankshaft of the engine to adapt it to the trans, had I done this swap I would have more knowledge to share

[DieselSJ]

We need pics. Engine bay pics. We want to see this thing.

[ivecowaggy]

This is what it looks like so far

[350 Vortec]

Looks like a good fit in there,if it runs well then you have a good motor for sure and worth looking after,intercooler and fresh air would be good idea in future (and a decent air filter )we rarely ever have autos behind diesels in anything bigger than a car here,just not suitable for hauling and mountains

[ivecowaggy]

The air filter is definitely on my list and I'd like to change it to a waste gate intercooled turbo set up in the future but running more than 10-12 psi of boost on this type of engine I've read is bad because of the 17:1 compression ratio, I could be wrong tho, more or less would want a turbo that spools up at lower rpm, I only see max boost when passing on the highway. And a trans with more gears would make a HUGE difference in the power output I think.
