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.

It's going to make decent torque, but the new Civic Si runs 14s stock /Euphoric

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).

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

So, are these the old style moving vanes(like the rotating vanes on the 89 Shelby CSX-VNT) or the new style(stationary vanes that move in and out of the exhaust stream- Like on my MB/Detroit powered FTL)?


Side note, I just read an article last week of a 99 Dodge Ram 2500 extra cab LWB running 9.96 in the 1/4. Not bad for a street driven 5500lb truck.

Diesel Performance? Its nice to see something refreshingly different. I'm curious to see some times/#'s as well so keep us updated.


Once you get it set up you should go race some Honda guys at an 1/8mi. track.

Not so much here either. Truck drivers have been doing it since the 70's at least. Ever since they realized you could get more power from larger injectors and changing pump timing. Remember...black smoke means POWER!!

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?

This looks like a tiny ass turbine wheel to me.

This turbo put my buddy Howard well into the 13's.

With over 200hp, and well over 350lbs of tourqe.

You'll need larger injectors, a larger injector pump, software, stronger rods, a hot cam, larger intercooler, and a few other go fast bits to get there though.

The sounds that car made on the dyno were down right terrifying.

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

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 \:\)

There is a slight possibility it will increase milage. Most likely it will stay within 1-2mpg. Many of the CTD owners have gotten better milage with basic bolt-ons and a tune. And increasing pump timing from 12* to 16*.

Why SS instead of aluminum? Aluminum isn't going to corrode from intake air. Just coat the outside and you are fine. Saves a few pounds over stainless.

its more expensive.

who runs into corrosion issues with stainless piping on thier project car ?

the car will probably be long dead before thats an issue.

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.

back when I bought my stuff stainless was quite a bit cheaper than aluminum around here and LNX lives in my area.


maybe its diff in Cali or things have changed since then. I dunno. That is something LNX will have to look into for himself.

Not to mention stainless piping was way easier to find locally.

My turbo is a fucking frankenstein!!!!!!!! I gotta grind down this pin in order to rotate the exhaust housing so I can get the oil feed line within 20degree's of vertical. No other vnt20 I have seen has this pin. I have the turbo completely apart, I can take some pics of the vnt internals if anyone is interested..

BTW, finally got the exhaust manifold!! I am going to have to get it sandblasted, then hot tanked... It's got a nice layer of rust on it...

:EDIT: Pin pulled out with a pair of needle nose \:\)
