Tuning a 2,5 l diesel turbo, year 2000, 115 hp.

[PerreHedlund]

My Chausson 35 camper weighs 3500 kg, has a 115 hp engine and that’s to little, I think. I’m looking for 140 “on the paper” (rules) and many 150/160 for real. I’ve been searching for a replacement engine without success. Now I’m thinking of buying a new injection pump and a new turbo instead. I’m very interested if there’s some good recommendations from someone in this form! Thanks in advance, Per Hedlund Sweden.

2000...?? Mk6..?? If so they are 2.4 not 2.5. The highest ps rating for the mk6 was 135ps....not sure if they can be reliably mapped though.
The only way you'll get 150-160ps is to "re-engine" it with something other than a ford transit engine.

Good God Knobby what are you drinking https://vantuner.co.uk/services/transit-power-tips/
Op scroll down the link and give Martyn a pm. 115 are not TDCI and can be tuned very successfully

Has anyone considered that this could be a (rare) Mk5 2.5 TDi 115ps intercooled with an EPIC pump

Aye, I did see that...but he wants 150-160....I don't think a TDDi 115 can be mapped that high and still be reliable..??

Just for the record... its 2496cc, type: 4ED*ZIFF.20-21:A Turbo : 530A 10 , Pump: 7187.002 2 and after asking the “motor vehicle inspection”, changing engine is not an option. I have to “tune it”! And I’ll go for 150 hp. // Perre

In the '90s I visited Sweden every year in my Mk3, later in Mk4 - and I never met either Transit. Per several years either Transit. In Sweden Transit with 2,5D engine it was absolute terra incognita. And still it is like that.
So our colleague from Sweden don't know, that idea about 150 HP from 2,5TD Epic It's a fast way to get big problems.
If is it even possible...

PerreHedlund - dude, stop think about it. Engine 2,5D it is construction from 1984, known as very reliable with power 68 - 85HP, small number was with power 100HP and very, very rare with 115HP. Power 115HP it was swan song of this engine in ordinary using. It is really enough for this engine...

The usual marinised version of the 2.5 DI Turbo is rated at 130PS, and it will happily run at that for years.

To get the sort of output you want you are going to need to look into a bigger/more efficient intercooler (Mk6/7?), possibly a custom turbo to give the airflow - though I suspect the standard one will just about cope if you raise the boost, and a custom built/curved/hybrid Bosch pump to stop it smoking at low rpm/loadings.

I ran my '85PS' N/A conversion for 80K miles with the boost at 18Psi and the fueling wound in to suit (I did try 20Psi, but the 141 pump was getting towards the injector flow limit and started wearing the cambelt rapidly). The only ill effects being drive line consumables; tyres, brake pads - it ripped the centre out of a cheapish clutch - and fuel comsumption if you used the 'performance'.

Yes, I know, but compare how many hours engine works on water to how many hours it works on road. Two different worlds...
Take into account second thing - camper it is van drivin' on long routes many hours - but with parachute on the back. So many hours gas pedal is pressed still deeply.
Engine 2,5TD done to 150HP in camper - It's a fast (very fast) way to technical catastrophe.
I know what I say. Look for picture.

I do agree, but is that any worse than bouncing off the governor trying to make headway against a tide in a river estuary.

Usually, the marinised version are derated , as boat engines run under max load for sustaining periods, a situation that rarely occurs in cars. So the situation that the marinised version is more powerful is an unusual exception. This fuels the idea that cooling & lubrication are up to expectations, and the bottleneck should be sought elsewhere.
Suggestions that come up in my head first are either emissions or max. torque. The 115 PS version had some sort of emission control IIRC, so it could be that they could not get more out of it within emission limits. Or maybe the upped torque would exceed the gearbox or diff limits.

It might work reliably though if one used the power with common sense. Adding an oil cooler, EGT meter and a bigger/more efficient intercooler as well as running synthetic oil would surely give more peace of mind.

If Jim ran 18 PSI and the fueling kept up, he must have been quite near to the 150 PS figure. @ Jim: was that with the original 85 PS injectors?

Ciao, Kai

Is it just different injectors fitted to make the power increase from 100ps to 115ps, or are there other differences too?

or put another way, What would you need to do to the 100ps turbo engine to make it 115ps?

If you mean the 2.5di the 115 (113) had a intercooler i think from an rs turbo, to be honest they didnt feel much different from the 100horse

It's like that, because EPIC 115 HP was mounted usually to heavy or big models (Jumbo, Campers etc.).
Difference you will feel if you compare small Transit L1H1 with 100 and 115 HP. Especially about acceleration on lower gears - 100HP has torque 224 Nm, 115 HP has torque 256 Nm. It is about 15% more...

the fact the gearing was the same as well
