M2 makes a nice ball bearing upgrade, Pettit also makes upgrades that can be run sequential. BNRSupercars makes upgrades that put out good hp but should be run non-seq. since it will put much less stress on the shafts.

if i were you and i was planning to spend that much money on seq. turbos i would rather go single but then again you would have to buy an ecu upgrade plus a fuel system upgrade.
