500-550 is really my starting goal, which is perfect in this kit but would love to down the road build the engine a year or so later and push towards 650+ if possible. How much of a potential difference is there with the upgraded 67mm turbo. Thats the largest that fits the kit i recal reading somewhere correct?

The 1.15 a/r turbine housing will reduce back pressure, allowing more fresh air in to the combustion chamber...translating in to more power. The spool up won't really change to be honest.

The 67mm turbo (which you can purchase with the kit for $200 extra) will get you well in to the 600's. I have customer with the 6266 on a VQ35DE in the mid 600's on pump gas. That is the smaller turbo, and smaller turbine. Supra guys have made over 800whp with the 6766 turbo, so it will make a lot of power.

The nice thing about this kit is that you can get the 67mm turbo upgrade for $200 now, go with the 1.15 a/r turbine housing and then when you build the engine it is only another $250 to upgrade the turbine housing...allowing you to max out the system.
