That sounds very interesting - it's an option I've been interested for a long time, and as VK Motorwerks doesn't seem to come around with this, I'm all ears!
BTT on the turbo upgrade: I received a lot of questions on the German boards (where I posted the info from TD about the upgrades) about the ability of the HPFP to cope with the upgraded turbos. Do you believe with pushing more than 500hp we're still within limits of the stock HPFP? Considering there's no alternative available presently...
Another question: As we're entering a territory of around 200hp more than stock 335i, do you think that other pistons or piston rods are necessary? I seem to remember you installed the low compression Mahle pistons - do you think that is essential? My garage also thought that with pushing the engine to around 500hp better piston rods should be taken into consideration.
