Phew where to startI will drop it with H& R (most likely with Bilstein B6 shocks) + spacers; most likely after winter. My truck has 203k km on OEM shocks, it can almost be considered maintenance and not covered by any warranty. This is definitely a GO. The look will improve for sure, no doubts.
however, like I mentioned before the power upgrade is more of a whish list at the moment than a real shopping list. I want to get the grossery list along with the performance gain and evaluate if it is worth it or not before making a move. I won't purchase anything before that. Now I know I am NOT looking for a crazy 2872 turbo or something like that. I would go a more conservative 2260 or 2265 to minimize turbo lag.
bare minimum for more power:
turbo is 1500$ ish, tune is 250$ USD
so looking around 2k$ for bare minimum, rough estimated power would be 330 crank HP to max out the fuel delivery system.
Is 2k$ justified 50HP. Not a No, but definitely a clear yes. Still need to sleep on it.
225$ USD tune for DPF delete (as I am stage 2 already) if done at the same time
approx 1000$ for DPF delete (Buzkken)
+++ if CP3 or injectors upgrade.
My guess would be that another 2500$ would be required to get a solid 350-370HP at the crank (with DPF). So total would be close to 5k$ for 100hp, which is quite steep for the power gain.
There is still some thinking to put into all that.
You're dropping it with H&R and Bilstein B6 - check. That will make for a great handling Touareg.. but will also destroy its prowess in the snow (which I know you get in Canada)
Next - what do you mean "spacers"? Do you mean wheel spacers?? If you're referring to lift spacers, they will not work with a lowering kit
Turbo - you are WAY off. You are looking at British pounds - once you do the conversion, pay the fat ass VAT tax etc.. you're looking about $3k USD for that turbo
There are NO drop-in CP3 kits for your car. So, while you can spend the $2k USD importing the CP3 upgrade.. you will be custom engineering the actual install and engineering your own parts to get it to work
For 400-450 wheel horsepower you are NOT going to be in it for less than $5k USD and thats doing most of the work yourself.
The point of deleting the DPF is for minute performance gains.. but massive reliability gains and a huge drop in EGTs and a huge gain in off-boost and also on-boost response10k$ is definitely a no go for such power gains. we'll see how it rolls out. The DPF delete might happens anyway if it get troublesome, it is most likely cheaper to delete than OEM fix. As there doesn't seems to get a significant power gain, but definitely a big change in emissions I'll wait. I do a lot of short city driving...
Turbo upgrade would happen if the turbo fails AND I cannot get it fix under warranty. we'll see!
As for the tune price, Malone only charges the tune price difference +100$ for re-flash when changing tune. I already paid 650$ for stage 2, stage 3 is 800$ so I have to pay 150+100$ for the new tune. If I do the DPF delete, it is another 250$ on top. If I only do the DPF delete, it is 250$ + 100$.
I got a quote for 1100$ CAD for springs with installation (springs are 500$ CAD alone), I find it a bit steep. Considering the struts have to be remove to install the springs, the truck/struts age and significant amount of labor involve, I want to do it properly and do the shocks at the same time as the springs. I expect the suspension bill to be a bit more, most likely top plates and some linkages/bushing will be required too. Doing only the springs now, and upgrade the shocks in a year or so doesn't make sense financially. The plan is to keep the car 5-8 years, so I guess I can get most of the life out of the B6 struts. All in all, this should be just over 3k$ CAD for struts, springs and spacers.
springs, 450$ (275$ USD for ECS or other)
struts: 1600$ (1581$ from rockauto, if no duties)
spacers & bolts:400$ (225$ USD + shipping)
duties, taxes, alignement, surprises...
The reason for expensive spring install is because they charge 'per axle'... Per axle I was quoted I think $500 USD for the rear and $550 USD for the front for any work involving shocks, springs etc. Its worth it- its a bitch working on these cars
