s6 plus 2.5tdi project

[raymor]

nothing big thing. i changed the fuel pump, but not important.
the lines are same.
its much easyer as i thinked.

Hmmm... all the lines are new on mine.

Were there any big problems - wiring etc?

[goodall]

this is interesting and i guess fair enough if you want luxury and you need do big miles
and i guess performance wise once your in boost be fairly quick
also it a s6 avant so i guess super perfomance isnt what you want just something quickish, s2 for the out and out performance

but then just seems wrong to do it to a plus since wasn't very many of them, was the motor blown?

im split on this.
i guess what will decide it is, what the note the exhaust like, diesely or subtle with a reminiscence of the UR 10v

[istoo]

personally rather torn on the idea given the significance/rarity of the S6plus, the first every Quattro GMBH car, pre-dates the RS4 and RS6. Its a real piece of history, not forgetting this had a near identical power to weight ratio as the RS2, so it wasn't slow to start with.

s6 plus exhaust note is rather sweet!

Well it's Arons car he can do with it what he likes to be fair.

Great project, loved to know more details on the turbo etc and how it all bolted together.

One mans poison... Not disputing that, hence why i said personally just wondered what happened to the old lump?
I came close to buying one last year so i am more than familiar with them. Contemplated RHD conversion, LPG, then decided against it on cost and taking away from what it was. But Arons capable no question there, gives him an almost unique starting base, if the engine was shot then fair enough. Personally i would have kept it as is, but there is a fair thread of original vs modified cars here, sure we can all co-exist.

@Aron: Not sure if you know, if its of use www.s6plus.de, for other parts breakdown.

Watch with intrigue, especially if the old lump is still running and available.

Aron,have you used the original AEL ecu?or something else?

That's a great project. I am in a middle of installing a 2,5tdi 5 pot into my 4000 quattro (90 quattro typ 85 for you guys).

Can you share what was done to the engine other than the turbo to get 250hp?
What injectors, any mods to the pump, what software?

Thank you in advance!

everything was easy. i worked on the engine and the interior. my electrical guy made all wireing. i just see, he pluged some cables, nothing big deals. he spent only oned day for wireing, included uninstall the original wires. now all things working, like gauges, cruise control.

my reasons was for this convertion this is one of my favorite cars. i go more than 100000kms every year. i think its 2 good reason.

not so much. i am using kkk bv50 turbo, race diesel injection system, brand new pistons, race bearings and a good remap to 2 bar.

[Rocco]

how many hp do you have more or less with this engine working with 2.0bar'??

230-250hp

[raymor]

Cheers Aron... I think my mind is made up

Well I can take some solace that you know what you have. What has happened to the original engine? i.e. did you start with a working car then transplant or was it in need of attention/ broken engine (saved)?

I understand the mileage, i don't do quite as much as you circa 50k miles a year between 3 cars. Can never have enough cars and options. one fast one economic seems to be the current favour. But i understand the need for combining both of those, will come back and check on this thread as its interesting... good luck.

Sorry, but still not convinced, in 3 years of looking I only ever found one s6+ in the UK, I know of another and thats it. A man with your talents could have had a very special S6plus.

i like the diesel eats 7,5-8 liters/100km

that is on longer distances i think? is slightly better than my C5 A6 V6 2.5TDI that has a lot less horses...

Thank you, quick question, the race injection system, is it a special pump, what size of injectors (nozzles) are those? Larger than .216?
I know there is lots of chips for AAT etc. but my engine is the original 1T without MAF, know anyone who does chips for that. Box looks identical and is the 55 pin Motronic plug.

Thank you in advance, we don't have much in terms of I5 TDI here in Canada.
