i have done some work on a c250 for a guy, pump is standard 6mm, for now.
turbo is kkk from Man truck
stainless 2.5inch straight through exhaust.
more fuel added by potentiometer.
custom downpipe.

went to the dyno today and i soon discovered from my egts and some experience that pump timing is out. Under further investigation i discovered some red paint marks on crank pulley, o dear, pump has been taken off by someone who doesn't know where timing marks are.
power started of at 188bhp and after a small advance i had 205bhp with 260 ft lb.
egts came down nearly 200degrees.
so, tomorrow i will check timing and maybe have to remove pump and fit correctly, i am nearly sure timing is still out.

I got 260hp with original 6mm pump
not only agree with potencimetro, the car is accelerated and the lame work ... with Reprogramation is better

(05-10-2013, 03:19 PM)dcm Good results so far, is everything else standard, intercooler?standard intercooler at the minute.
What's the plan for the timing, how did someone manage that?
i have timing pointer now fitted from another old engine and have no idea why someone would remove it.
going by the dirt in the threads, its been missing for a while.
pump coming off on monday. timing light says 16 degrees btdc.
would like to try some more advance.

nice job there Manta, Ive a 250 estate "98 manual put a 2.88 diff in and had ECU chip upgrade and DPF guts removed allegedly 175Hp 80mph @ 2500rpm now, because of gearing Im not using this engines ideal rev range for torque I need it <1500-2000+ and not 2000+
It pulls like a train over 2000 but terrible under and need to sort it, does your conversion with the KKK give better lower down boost, is it from a 7.5 tonner with manifold pressure driven wastegate ,cheers

it isn't great in lower revs but once it spools it pulls like a train through all the gears.
more rpm would be good.
yea, pressure wastegate from 7.5 ton MAN.
turbo size beside original.

yeah, Im trying to get common rail like acceleration at the lower end may have to go with variable vane perhaps , nice welding on that metalwork by the way ,when you welded that exhaust manifold up did you have to heat it up first or is it just maleable cast, I just feel something can be done about the lower end dead area cos its a real killer. itd be nice to hang onto 4th and 5th more without giving 3rd a hammering on inclines corners

(05-15-2013, 05:27 PM)mantahead got the timing sorted, not much more power but lower exhaust temperatures.(650c)
maybe try a remap and get the revs up a bit and see what happens.
here is graph.
how much boost do you have ? whats beckpresure ? with 6mm elements modified mechanical pump i'm geting ~150cc of fuel

A few lads i know have the kkk off the 300. If you ream out the hotside of the 306 kkk itl slot right in.
Very easy upgrade but they arent easy to find!
If you have any lying around let me know...
Any thoughts on making that an mtdi? Do away with the electrics?
Is it a t25?

From what I've seen C250s have a Garrett GT25C fitted and E300's have KKK K14 turbos with the same 3 bolt flange.

Retained the rack potentiometer from the electronic pump and connected it to mech linkeage? Or does the ecu just work with it disconnected?

fueling on my 606 and I didnt find anything so far about using potentiometer.
Would you be so kind to provide some info describing it. I bet few of us could use it on DD.
1977 300D for parts? Just a pile of rust but still runs!
1984 190D 2.2 - gone to better home
1987 Dodge Maxivan with OM603 and Goran’s 7.5 backroads terror
1987 300TD - tinker toy
1989 300TE - parts
1991 300TE - backyards decor
1991 300TD - Barrote’s 7.5
1992 300TD - semi-STD(Goran modified 7.5 ip but still with factory turbo+at)
1998 E300TD - dd with DSL1 now
1998 ML320 - snow ride
2014 Sprinter 2500 - Malone’s tune + pedal box
How do you install the potentiometer to controll rate of injection? I am researching how to raise

(05-16-2013, 12:12 PM)mantahead shortened the intercooler pipes and removed that pipe that the turbo was heating up. made a new pipe out of aluminium, and onto stainless bend and 90 degree silicone.
not much room for clearance with bonnet and washer bottle.
Hi,
I've got a question.
You tested a straight pipe above the turbo between intake manifold and original plastic pressure-out from the intercooler and also the self welded pipe from above (that one next to the water tank). Was there any improvement with your self-welded pipe? I have also thought about both options you've mentioned, that's why i'm asking.
How was the improvement on removing the AGR inlet and replacing against the straight pipe?
