I thought I would post a thread here and I will link it over to Club Touareg. There is just way more information and people who have modified their TDI engine.
A little history: I purchased a used 2004 V10 TDI Touareg sight unseen. Loser dealership in KY lied and sold me a complete lemon. Thru some investigative work I found that my cams and followers had worn. One all the way thru to the valve.
I started the tear down in September and after realizing you can't do it in the car I sent it off to a mechanic that had some working history with the V10 Touareg.
I wanted to post up my build plan and see what the thoughts are here. Pretty much everything has to be done with the engine out so I'm doing as much as possible now.
I am sending the GT1852V turbos off to Scroll Products in NJ to upgraded. I will keep the stock turbine but will go with a 60 or 63mm compressor wheel and a larger thrust bearing. I will most likely go with the 60mm. Thoughts?
Because the cams are over $800 a piece from VW and have to be ordered from Germany I am sending them to Frank Irving in MO. The heads will get fixed and the cams reground. We really haven't talked stages specifically (frank are you reading this?) but I was thinking of going with stage I or stage II profiles. This will be a DD and a towing rig. Not really a drag strip car but I want it to do it if I get the chance. Thoughts?
Will be getting the new hardened followers. No brainer.
I am gutting the exhaust completely. There are 4 cats and 2 have to be removed while the engine is out. How do you go about gutting them and leaving everything around the housing in it? I will be doing this part myself as a conflict of interest obviously with the shop performing the work. I will have the rest of the exhaust finished off when it is up and running.
I'm thinking of having the injectors rebuilt (I think they are fine) or just sending them off to have new nozzles put on. I have done this in my fords before but not VW. What are the thoughts? How many CC flow should I be looking for. Are the race nozzles to much for a DD tow rig? I don't mind a little smoke but I don't want a belcher.
I had talked to Mark Malone before I found out my engine was bad. Because I have a bad o2 sensor and the cats will be removed and the fact that you have to remove the engine to replace the 02 sensors I'm going to have them electronically deleted out. At the same time I will be getting a custom tune for the said setup I have. Goal in mind right now is 400HP and 650LB to the ground. But would be happy with less. Shouldn't be to hard considering they came 315 and 550 at the crank. I figure if you guys are doing over 200HP with 4 cylinders I should be able to double it with 10 and still make it a DD vehicle. I could be dreaming.
I am also thinking of having the EGR deleted as well. Thoughts? My EGR pipes are a ***** to get to and I think my valves may be bad anyway and don't feel like replacing them. It completely gunks up the intake anyway.
Last but not least I will be tapping for a EGT and boost port. I plan on running a glowshift single pod gauge and will run EGT/Boost/and Trans Temp senders. With these I should be able to integrate a water/meth system. Another V10 guy in Australia has done it and said it made a big difference in his TQ but had no gauges to monitor drops in EGTs.
As of now there is no way to upgrade the intakes on the T-reg so I might be stuck there for now.
I have already upgraded the drive shaft with a stronger support mechanism from Vortex.
I'm not aware of ARP making head studs. Both heads have to be removed and tightened as a sequence or it will warp the block. Plus they very very very long and hold the entire engine together.
Any thoughts appreciated. I'm worried that doing all of this at once will make it harder to tune and get settled (or running at all). But sadly due to the cost of these engines and the necessity to pull them out each time I can't afford to do it any other way. Turbos , cats, and Cams have to be done now. Injectors could be done later but if I'm in there I might as well do it. That and if Im' going to block off the EGR I need to do that now as well.
Thanks guys.
