cruising ebay and I found this compound turbo setup.

Its off a 2009- IVECO LDV 3.0L. I know it may be a little big but I have been wanting to do a "performance build" The stock 3.0l Iveco makes 140HP and 258 ft lbs

copy pasted from a site i found on the web.

The heavy-duty variants of the 3.0-L engine are rated at 140 hp (103 kW) between 2990 and 3500 rpm, with peak torque of 350 N·m (258 lb·ft) between 1250 and 3000 rpm. The higher output variant of the engine is rated at 170 hp (125 kW) between 2990 and 3500 rpm, producing peak torque of 400 N·m (295 lb·ft) between 1250 and 3000 rpm. This represents a slight reduction in peak power output compared with the light-duty Euro IV ratings of 146 hp (107 kW) between 3000 and 3500 rpm and 176 hp (130 kW) between 3200 and 3500 rpm.

Torque output from the light-duty variants is the same as from the heavy-duty variants, although the band is slightly narrower for the 146-hp variant. Peak torque is produced between 1400 and 2800 rpm compared with 1250 and 3000 rpm.



Has anyone ever messed or seen these? I can not find specs on them at all.

The 3.0l seems to be a higher rpm motor then the kubota. I may hold off and do a build on a v3600 I have been watching.

Once my current 2 XJ swaps are done i may play around with a set

Thanks

Not sure if the same concept applies, but I was told gas engines with twin cam heads, like Honda's and stuff, can way outflow an OHV head, so that might be an issue. And trying to find a governor setup that will supply fuel up to the high rpm you need. If you can get a V3600 that would probably be able to push enough air to spool the turbo's. I know Redveloce ran a twin setup on his TJ.

Looking more into this compiund setup and the small turbo appears to be a k03. Similar to what is popular with the v2203.

i sent the seller a message for more info and part numbers if available

 

Has anyone found the fueling and boost threshold for these engines yet? It seems like fuel won't be an issue, but I think I remember some people talking about a lack of aftermarket forged pistons available for a bore of this size. That might drastically limit the performance gains of the compound setup.

Oh, I know whenever I go to get parts the parts guys give me a hard time about needing a specific Kubota part number for the engine and equipment it came out of, and I was talking to my dad about it the other day and he said CAT was the same way. They needed all the numbers so they know exactly how the engine was built. Does that mean there could possibly be different fuel cams and camshafts available for these engines? Since they were used in all sorts of construction equipment, tractors, stationary pumps, and they came NA and turbocharged. A turbo grind camshaft might be helpful with boost. It is at least in gas engines.

I do not think fuel or boost limits have been found

I did recieve an email thru my site the other day of a guy trying to take a v2403 to 400hp and 800 ft lbs. But when i asked about details he blew me off pretty much telling me its his secret. And i wouldn't go give out all the dimensions of my adapters why should he give out his motor build details. Anyways he did say his pump was out getti g reworked.

Claimed he is on his 4th motor though. I told him I was after 150hp 350 flt lbs with my next conversion. And mentioned this compound setup I had found.

I am so tempted to hit "Buy it now" the seller doesnt want to give any info either. He just asks for the part # from my old setup to make sure it works even tjough i told him it wasnt being used as a replacement. I understand he is trying to cover his own butt so no hard feeling.

400hp and 800ft lbs of torque, out of a low revving 2.4L OHV diesel? I don't know about that one. I don't even think the 4bt guys try to push that for a street rig. I can only imagine how the first three engines died.

I had a hard time finding information on my IHI turbo. Anything used on a Euro spec diesel is hard to find information on, unless you know what Euro forums to get on.

Yea i was surprised. I am not sure why anyone would spend that much or try to get that much out of a 2403. I like these motors alot but they have their place. Super higher performance is not one of them

 

They just don't have the displacement or the aftermarket to support them. They're great little engines making 100hp, but trying to turn them into an 800ftlb monster isn't worth it. I mean, if the guy has the funds and the ability to support it, by all means. We can learn a lot from him on tuning these engines and some of the hard limits. And like anything, someone has to be the pioneer and be willing to turn the screws up until it screams uncle.

Back to the compounds. I tried searching up the part number the seller listed and all I keep getting is a K03, which you said is the small one. You really need to find the compressor map for that setup, or at least the part number for the big turbo, and then kind of backwards extrapolate a compressor map for the system based off of the two turbo maps to give you a rough idea of what the system is based off of. Maybe try contacting Borg-Warner's tech department and see if they can shed some light on the subject.
