Project is finally starting to come together, piece by piece This was definitely what I was waiting for. Just waiting for the 1.6TD exhaust mani and I can start to figure out where things are going to go...
Garrett VNT20 off of a Audi A6 2.5 V6 TDI (180hp) This turbo is good to about 30psi.
:UPDATE: Still waiting for the fucking god damn exhaust manifold!!!! The shitty thing is, I bought it from a guy that lives about 3hrs north of me. Got lost in the mail, he sent out a new one lastnight. It's a fucking piss off, because I can't do shit without it.. Although I do have a question regarding the IC piping.
Am I am going to be upgrading the IC pipes, but need to figure out if I should go with stainless or alum? Pipe is going to be 2inch, I was hoping to get the local muffler shop to make a few bends for me.. Any advantage of one over the other? I'll hopefully have some more updates for you guys when I get the manifold and can finally fab up the adapter plate!!!
3bar map sensor has been ordered, along with a set of 1.8T axles. Looking for a set of 1.8T or VR6 108mm axles flanges now..

I am actually laughing as I type this, but yes...yes I am.
I won't bother guessing the power I'll make, cause Euphoric would be in denial But I have a pretty good idea.

Based on what others have done, what would be a realistic hp/torque number off the wheels. Feel free to low-ball. I'm growing increasingly interested in diesel stuff.
I am hoping for something around 180whp/350ftlbs.
Jon: I think the Audi's run about 22-23psi stock. I will probably start at around 25psi or so and see how the EMP is, no reason to run more boost if I can't get rid of it...
I took apart the turbo tonight and its mint, barely any soot at all.. I need to re-clock the VNT vanes in order to move the exhaust housing. I need to get the oil feed line vertical (or within 15 degrees of vertical).

LOL, 14.5@80 mph.
Im jk, it looks sick man.
Man, I'd be lucky to break into the 14's But I'll definitely take it to the track for shits and giggles.
Garrett part number is GT2052V. Housing states the A/R is .42. Exhaust is 1.03? I am sure someone knows what these numbers mean (I admit, I don't)

Pretty small but you should be able to get into the 14s

Scargoes: You are correct, identical vnt mechanism as found in the VNT25 used on the CSX-VNT. Most of the new variable vane turbo's found now are Holset's. But they require a big displacement engine to make use of them, I dunno if I could even spin one up with my 1.9 litres of fury
Jon: Is stainless cheaper then aluminum? I'll see if my local shop can get some at a decent price, its such a pain in the ass trying to mock up stuff with the engine still being in the car, with the original turbo still on it.. I'll have to get a mini DP made up and just take it to the shop when its running for them to finish up the rest...
I was even thinking of a generic Ebay IC kit. The IC pipes on the TDI are a huge restriction, and obviously there isn't a kit I can just drop in
:EDIT: I need to find a dyno in Toronto that can pick up rpm from my cam sprocket. I'd like to see where the car is with just injectors/chip before I throw more stuff on it. Jon, any idea's?

Be careful with ebay ic piping "kits" they weld like absolute ass on a plate with no shielding gas, and the silicone couplers aren't always silicone.
If you do a moderate increase in price, you'll find actually polished piping in aluminum, no a polish look coating like the ebay stuff.
I'm very excited to see how this works out for you.

Ian, thanks for the info. I have found a local guy that should be able to do up some IC piping for me. If the price is right, I'll pick up a GodSpeed core and just do a front mount. I have also talked to my tuner, who will be getting a custom map done for my car once I give him all the specs. Apparently people in Germany have nothing better to do

What the fuck? I do this every day, and use only the top quality materials, and my stainless costs more than my aluminum, period. When you finish off a 230cf tank of argon in two days, let me know.
Your typical 304/308ss is resistant to corrosion, but most welders don't know how to properly weld enough to prevent it. Aluminum simply won't, will save a ton of weight, and I typically see several degrees cooler IAT's by using aluminum, with no coating, wrapping, or anything like that.
The only SS that is as cheap as aluminum is 409, which is what toyota and honda use for their stock exhausts: it surface rusts but is very strong due to its high carbon steel content,and welds best with a 308l rod.
Back to the original poster, how does the tuning think work on small diesels? My only experience is with the duramax/6.0 and 7.3 powerstroke, and cummins. What sort of interface can the end user use, and what are the main parameters you are changing? Obviously a lot to do with fuel pressure.
Also if there are a few specific bends you need and I have them lying around, let me know the size and I'll send them to you on me. I'm interested to see how this comes out.

Ian, I appreciate the offer. I plan on replacing the stock IC piping with 2inch tubing, hopefully the guy I have planned to weld this stuff up for me does alum
From what I've gathered in a proper tune on these cars there are about 15 different maps that need altering. Timing, injection quantity, boost etc are the 3 main factors. I am pretty sure the fuel pressure is directly related to rpm (from what I have read) I don't think it's something that can be changed with the map, as it's completely mechanical. (Opening pressures, etc)
This is the pump that the most of the VW diesel's untilized until the release of the Pumpe Duse in '04 to the US market..
http://www.cs.rochester.edu/u/jag/vw/engine/fi/injpump.html Unfortunately no one has come up with a plug and play solution like they have for the trucks. You can do a lot more with a common rail setup like the trucks have compared to what I am dealing with. The only thing a tuning box is good for on a TDI is fooling the ECU so that it dumps more fuel. Does not touch the boost level at all, sure you'll get maybe 1-2psi more, but it's pretty much an expensive potentiometer.
I appreciate the feedback guys, keep it coming.
