Let me give you some things to consider.. I spent $10k alone having the APS TT kit put in my G35. The car cost about $35k.. exhaust, body kit etc.. it all adds up to about $55k altogether and I did not even build the engine. (By the way it has been proven that 400whp+ can be reliable in the VQ)

When you decide to sell the car (and you will) the turbo is actually going to DROP the value of the car.. in my case I sold for $28k. People spending that much on a car want something reliable or a warranty and outside of a built engine the VQ is not that.

If money is not an issue then disregard what I've said.. but also consider that the Z is not geared for high horsepower, you'll put down big numbers but still get your ass handed to you by cars that were meant for high speeds. Stock C6 Z06 will simply murder a 400whp 350Z partly because the 350Z is shifting twice as much as the Z06. If you plan to keep the car for a while and want a FUN ride, you cannot go wrong with the APS or JWT kit.

Take it to Forged, and I say that from experience. You have one of the best tuners in the country for the Z right here in town, I would never pass that up.
