junkyard turbo upgrades for a 2.8L diesel- your thoughts.

[Dez]

so, the iveco in the pickup is up and running and on the road. time to make it faster/louder/smokier.

current turbo is this, more or less. part no is actually 49135-05013 but i cant find that anywhere, i think as its a very late engine, they were making HDis by the time this was made.

49135-05010 Mitsubishi / MHI Turbocharger fit Fiat (Iveco) Daily II 103bhp 2.8 litre Diesel engines, 8140.23.3700 engine code, year 1998 onwards, OEM No. ME202345.

ive got a set of intercooler spec manifolds and pipework coming as i know i'll get more power gains there, but i also want more turbo. what do we reckon are the junkyard (i.e. cheap) options for something? i don't want it so big it wont spool til 3000rpm, so thatll rule out most big truck turbos, but i don't mind the power being bumped up the range, as its VERY low down at the minute, to me the current turbo is too small.

pump appears to be a bosch VE so i shouldnt have any problems with that side of things, i just need to know what to go looking for (and where) for the turbo side of things.

Saab turbos are cheap and plentiful. The turbo from a 2.3 full pressure turbo will run up to and above 300 horsies on a petrol so applying some fag packet logic it could probs spool a diesel up to 200 brake, especialy with the extra 500cc of capacity

[Colonelk]

Whats the max safe rpm for the iveco bottom end Dez? and whats the governor currently set at? 4k?

Also, do they do a higher power version of that engine? Would be interesting to know if they come with a bigger turbo.... plus means you can just bolt it on, and up the boost a bit too

[froggy]

I have a brand new gt2860 vnt from a 3.0 2010 daily that would work well

[retrowrongun]

Nice t2 should do well on that and am sure you can get adaptor flanges also , just make sure you can adapt the water and oil feeds to suit too

[ettorebugatti]

Current turbo could be a TF035 model?

MHI 49135-05895 from BMW N47 (x20D), it should be good enough to get you around 160-170hp.
Beeing a TF035 too, there might be a vague chance of a bolt-in. Although that might be not so much of interest to you.

elk- don't know and don't know. i got given a free engine, so the current plan is wind it up til it goes pop then do the other one slightly less

even fitting a tacho is proving a ball ache as all the aftermarket ones require a 3-wire american style alternator, and mine is european type 2 wire, so i need to swap out the alt just to do that. plus i don't know how you calibrate them? must just be pulley ratios i guess. or can you get trigger wheel driven alternators? surely someone must make one that works off a 36-1 i can bolt to the pulley, as that would be dead accurate.

there is a higher power version i think ('veco engnes are a total minefield when it comes to power outputs/etc.) but i think the power increase is from intercooling. mine is actually supposed to be 112hp i think?

froggy i'll have a read up as to how that differs to whats on.

ettore, hard to tell without a pic to reference it to, ile have a google around on that too. bolt in doesnt matter, the intlet manifold probably needs uprating a bit anyway, and i want to change the turbo outlet from the big ugly casting whats on there to a 'normal' V-band type really as it makes the exhaust easier.

[froggy]

No problem , if it's any use I'm going to pendine on the 27th for the vhra races

[mini-mad-nick]

stick a holset hx35 on there just go down a scrappy and get one off a lorry or something

[froggy]

The hx35,s over here have huge exhaust housings for 5-7 litre diesels so wouldn't work on a 2.8 . Petrol turbo from something around 1.8 -2.0 would be more like it

[Mark]

Subaru forester turbos appear to go quite cheaply.

[stealthstylz]

Seen as there's some good suggestions here, i need the same for the Granada. Its a 2.5 VM with a IHI RHB5 as stock. Any suggestions? Or even a idea of what boost the stock turbo is safe to?

[LowStandards]

Forget power

Turn the fuel up, ride slow, roll coal!

Dez: Really, astoundingly traveller method of running a tachometer from a 36-1 wheel would be to use a Ford EDIS-4 module; takes a 36-1 VR sensor input, gives a normal spark signal to drive a 4-cylinder petrol tachometer. You'd probably need to add a resistor to make it work, but that's about it.

[Dez]

astoundingly traveller suits me just fine

tbh though it actually sounds like the best option- cheap, reliable OEM parts that are scrap yard finds, and the option of running any cheap tach not just specific expensive diesel ones. plus itll be 100% accurate unike a alt-driven one. are edis 4 still cheap or has bangers/megasquirt shoved the price up? a trigger wheels is only about a tenner i think? i assume you have to use a ford CPS with it?

i think the first step is deffo gauge-up the motor with a tach and boost gauge so i can see whats happening, then figure out how to remove any governing off the pump. next step would be an adjsutable wastegate i guess as i havent got a clue what the current ones doing.

[welshpug]

was there not a rev counter on those 2.8 engines ever?

[Dez]

yes. according to the wiring schematics ive got, there was 2 things labelled as a tach drive- i don't know if it used one or both, as both were fitted? one was what looked like a mini-alternator setup with a winding inside the water pump pulley, but this was smashed when i got it (pulley had been hit as its still a fraction bent) and i had to remove it to stop it catching on the pulley so its all gone. assume it worked similar to an alt drive tach?

there was also a large sensor goes in the bellhousing that picked up off the flywheel/clutch somewhere, but no evidence of a trigger wheel setup i could see, like say a zetec. i removed the sensor but do still have it. now youve reminded me of it that may deserve further investigation, if its compatable with the edis unit that would make it an even easier setup.......

[chairchild]

a similar sized, but "newer" tech turbo is often all that's needed to get a bit more oomph

ie: yours will most likely have an old compressor, approx 52mm in diameter. If you get a Saab 9-5 turbo, of the GT1752 flavour, it may well release a few more ponies from simply having a cooler output. One to look out for, is a wastegated GT2056 turbo - should give similar spool, but a bit more power.


Trying to fit a vnt with mechanical control is always going to be a compromise... the compromise being having an engine that makes boost, or an engine that has any form of efficiency

If you're going VNT, make sure you have a mappable electronic control strategy for it (there are Arduino setups available). Any mechanical setup will always be trumped by a similar wastegated arrangement - I have back to back Dyno runs to back this up

GT2056 is fitted to BMW x30d engines also

But... only in the VNT guise (to my knowledge)
