I received a quote back about having a Technique Tuning turbo kit adapted for my non-M... days after I purchased a Supersprint exhaust (including headers, mufflers, connecting pipe). Let's say the quote is VERY reasonable when you consider everything included. It's similar in price to an ESS TS2 kit alone. PM me for details.
I'm spreading the news in case someone else has the cash lying around. I really wish I had gone this route instead of opting for the supercharger; when you start adding everything up, it ends up being much cheaper.
Technique Tuning: turbo kit + labor, custom 3" exhaust
Supercharger: supercharger kit + labor, headers + labor, exhaust + labor, high flow cats + labor...
My next question will be whether I could opt for the stage 2 kit (375-400 whp). That kit would have far more power than anything else on the market, and it would even rival a supercharged M. If I can get someone to buy my VF kit with 2k miles for a reasonable price, I may jump on it.
