I'm getting a Hahn Stage 2 Turbo this summer, and I was wondering what else I would need to upgrade to keep the engine running smoothly. This is what I'm planning on getting when I get the turbo:

1) Custom dual exhaust
2) AF/X - Bored Throttle Body: 56mm
3) AF/X - Underdrive Pulley w/ new belts
4) A'PEXi - Digital Super AFC
5) HKS - Type-1 Turbo Timer
6) GReddy - PRofec B-spec boost controller


Here's my questions w/ the components I've already decided to get:

1) Should I get a 3" downpipe & 3" cat, and 2 1/4" dual cat-back?
2) Should I bore the throttle body to 56mm, or should I bore it larger?
3) Should I only replace the underdrive pulley, or should I replace all of the pulleys? If I should do all of them, which brand would you recommend? AEM?

If there are any other mods you think I should do, please let me know. I will be upgrading to Stage 3 in the future just so you know.

Thanks,
Richard
