The om603 diesel pump should be first on your list.
I've got a holset h1e ready for when I do mine.

No real reason to change the pump as the 606 pump has larger elements and the ECU can be mapped for the cost of an EEPROM.

I can't remember the name of the member that has done his own.

I may be stating the obvious, but if you re-map the ecu you could in theory use a map to control a pump with 7 or 8mm elements?

I had a daf cf85 truck in for repair today, alot of those run a hx35 with a t4 mounting flange. Perhaps one of the truck breakers yards could help you?
Thank you .
I forgot "black smoke" has a Scania turbo. I see if there is any trucks in the breakers here...
If I change the pump I'll go for the Dieselmeken one fitted with larger elements, but it need a remap too and also a larger turbo... Or I need a non electronic pump but this might be a tough one with all the electronics on the car but I think it'll be better... I prefer a mechanical link to control it.
Cheers.

Dieselmeken seems to know his stuff. He's been sending me details of this device to emulate the missing ALDA on my uprated 606 IP.

If you go for a mechanical pump Olivier what is the gearbox going to 'talk' to? At the very least it needs a TPS to operate.

I am hoping that the gearbox has a brain of his own and that it'll be changing gears properly...
I am hoping that I might be able to leave a connection from the old pump to the ECU, then even if it freak out and want to cut the fuel, this shouldn't affect the gearbox, unless it decided that enough is enough and put the car in limp mode...
I am not sure the gearbox is linked to the TPS? As the gear change varies more with the load then the actual position of the pedal? I might need both tho?
Is the speedometer in the gearbox as well?
Way tooooooo many electronics there

The whole thing is canbus so who knows what talks to what? But I know for certain the gearbox needs TPS connectivity cos when I was thinking about using the 5sp gearbox I've got I did some research and the box takes a signal from the TPS for sure. That replaces the old mechanical cable pull system on the 722.3. You might even find that the box wont change up without an engine load signal from the pump ECU. Not sure about that though. However, if it is only the TPS and if you're going to do a cable throttle then linking it to the cable pull for the TPS should be easy. In fact you could spur off the TPS to save you going through the bulkhead.

Humm, more complications...
Thank you for the hints.
I need to see Mike and Steven next month when I got enough to rebuild the lift pump and order the parts from them. They are both really nice lads , really professionals and Mike's shop got keen prices too Top Class shop

The manifold ideally needs an elbow to allow the turbo to sit higher and match the exhaust. If you have a look on superturbodiesel you'll notice there all positioned high towards the front of the engine. Someone on STD was selling a HX35 with different exhaust housings in N.Ireland.
Couldn't see it on STD?
you wouldn't have a link you could send out to me in case its a different one and its still available?
Cheers

Why not fit two standard turbo's. That should be good for about 500 Bhp but spool up quicker than a single large one.

I just checked, it's the same guy and it's all sold.
Are you keeping the 6mm elements?
I was thinking of this too, but I don't see how to attach then together, and the cost would be very similar then a big mama, then may as well go for the truck style?
I am looking at the turbo first, then the pump, but its all costly.
I am just window shopping to see the options available before doing anything, but the electronics start to really bugger me now...
If I do the pump I got the whole thing coming from Dieselmeker, then I would be able to use the car while waiting on it, and would have the spare one.
But again I start to despair with the electronics as the whole ECU need to have a "rethink" and its another 220 quid...
I am looking at a dump valve today, see if it could lower the PSI this not to freak the ECU too much but the more I think of it, there is nothing I can do without a re-map...
Yesterday I re-open the wastegate ( ECU freaking too much on the highway at cruising speed) but tighten it at the acuator to get more boost, then I have the yoyo PSI again, 22 to 15 going up as the ECU see over boosting open the gate, then close it etc...
Its a pain...
