Hey Cog in the future you could go for the bmw 123d twin turbo 2.0L with 204hp 255hp with a remap
i would if it came with a bigger boot

it was on the shopping list when i noticed they tune up to 270bhp on stock turbos and injectors. in such a small car would be great. but with a boot smaller than my john thomas , its hardly a family vehicle .
they cant half go though

If someone could get to the software in the brain of the pump we might get somewhere. These seem to act really weird. I dynoed one AKE yesterday and it got 201hp and 412nm. With both 58mg and 63mg iq... Something is limiting the injection duration to that. No smoke at all. If it would be the nozzles then it wouldn't be as drastic limit.

There are some sneaky limiters on ecu that you need modify.

Amen to that! Its a turbocharged boat anchor.

The fact that no one will share any info about what those damn Iveco nozzles are doesn't make it any easier to diy tune either.

Long live the 1.9 I4

TurboDynamics do a hybrid that drops straight in called the MD438 hybrid and together with the B.683's gives around 265hp if you can get your hands on a set!

I totally agree with adamss24 about the VP44 ip as its definitely not the weakest link by far , the main trouble here Adam as you probably well know is getting someone to modify this pump and other pumps over oem spec's all they want to do is say "modify the pumps son no we just put them back to Bosch spec's" but there are a couple of company's out there still prepared to do something over oe.

I am arranging to go back into celtic to see if the 3" exhaust takes us any further. If with bigger nozzles, hybrid turbo and a remap we get 266hp, basically bolt on extras, surely someone who into heavy modification can get further.

Has anyone made an m-TDI from one of these yet? Something like a Volvo or truck pump maybe?

I dont dislike them at all ! I had a few v6 tdi's and even high mileage ones did not give me any troubles. I do buy them most with engine troubles as spares or repair. The last one i bought broke the cambelt after i replaced the cams/lifters and trust pads due to a cheap Dayco belt wich was previously fitted by a garage for the last owner. It only had 1000 miles on it when i got the car so i did not replace the belt, shure enough it broke and it gave me loads of fun 3k after the rebuilt. Funny though, no valves were bent and it let go at 80-100 Mph. The early design with rocker arms is safer as the moving pistons will hit the valves and the rocker shatters thus saving the valve train. The valves are kept shut by the springs and if you dont re-start the engine there isnt much to break... I have just bought a cheap allroad v6 tdi last night and it looks that i'm gonna get my hands dirty again- no engine trouble but susp. arms, brake pads and cv joints needed for the Mot. I had a few 1.9 Tdi and they are too rough for my liking + a good v6 tdi engine really shifts when pushed hard and god it sounds good for a derv ! The drivetrain is built to take the torque of the engine unlike the 1.9 wich is not propper engineered for big power hikes. I was thinking to buy a 1.9 Tdi quattro a4 (b5 shape) and do some tweaks on it but it would require too much work to make it feasible: 6 speed 01E gearbox transplant, 244mm clutch and much more. I even built the engine pretty well but had found no decent car to put-it in ! On the other hand the b5 a4 v6 tdi quattro wich i also have its a wolf in sheeps clothes: rs4 rear diff/subframe/suspenssion/brakes, front 4 pot calipers and 330mm discs, 180Bhp AKE engine with some tweaks, s4 front/rear bumpers and much more. Next is to strip the car off its unvanted front seats and replace them with Konig bucket seats ! I just had a 4 wheel alignment at Wheels in Motion and it totaly transformed the car ! Next is a respray and maybe a full stripped interior.

What's the price of "rs4 rear diff/subframe/suspenssion" and will it fit an A6?

The 2.5 V6 tdi was never offered in the USA or Canada.

The most powerful stock engine was 220 bhp.

The 3.0 is a much better engine with stock power of 240 hp.

RS4 will not fit an A6.

I had one with a 3L block,psi tuning chip and a hybrid turbo a few years ago- 254bhp (i still have the engine in a FWD a6 saloon allthough detuned: stock 180Bhp turbo and no chip or injectors-still spinns the wheels in 3rd gear !), i am driving now a mildly tuned a4 quattro with a 180Bhp AKE engine,rs4 rear diff,ATE 4 pots brakes/rs4 rear brakes, iveco nozzles and a PSI chip, about 220-240 Bhp. Working to fit a KKK turbo off the 3L tdi engine and looking for Bosio race 683 nozzles as well ! I also have a a6 tdi quattro on wich i have rebuilt the engine twice (first due to worn cams, 2nd time due to cheappo Dayco cambelt snapping and wrecking the engine). Now the AKE is boasting mildly polished Brand New heads, thicker 3 notches head gaskets, Steinbauer P-Box, the injector pump has been rebuilt and i am fitting a GT2559v off a renault 3L dci. This is me tow car and is regularly towing a 3.5 T car trailer. The a4 dances circles round the a6 though as its 200Kg lighter. The thing is the v6 tdi isnt that loved in uk (grease monkeys find it difficult to work on ?!) and there isnt much stuff of the shelf. Most tunners say the injector pump is the limiting factor on the v6- i beg to differ- there are cummins trucks who run modded VP44 pumps wich can supply fuel up to 1000Bhp. Also i know that the same pump has been used on Jcb and MAN trucks (allthough they have a 24v ECU) so these should supply decent fuel to a hungry 6L v6/v8 engine ! The 24v are also rarely failing unlike the 12v Bosch computers ! There are no aftermarket cams for it and the audi heads are overengineered so there isn't much to improve on. The only thing i would upgrade is the inlet manifold but isnt easy to do as the injectors hard lines are running over it. Fit a bigger FMIC and you will be good to go !
Will Cummins monster pumps fit to 2,5? Where is stock pump limiting power? How much will stock con rods handle? Thinking of twin vnt:s and 400+hp :lol:

The Cummins pump does fit the same way as the VP44 pumps fitted to the audi's. Rods will handle up to 500Bhp and the bottom end is allready strong enough with girdle to keep-it in one piece. You will need to lower the CR though and by doing so you might experience hard starts if timing is not adjusted accordingly. Its not the Bhp you need to worry but the torque as 250-300 Bhp will get 600Nm very easy and there are not many aftermarket parts out there for them...for once the clutch wont take-it without complaining. Twin 1852 turbochargers from the opel DTI 2.2 L will do that nicely...
