    so i was thinking of rebuilding my turbo @turbolabamerica he offers a bigger turbine with billet alum and more fins on both sides also he can machine from 40mm to 44.4 and 45mm to 50 which is the size of the k04 turbo.
    so my question is this a bad upgrade i hear bigger turbo loose of power or should i leave the size alone and just add the lighter turbines on both sides with more fins
    i have a A4 b7 stage 2 full exhaust and air intake also stage 2 clutch since i burnt out the original 73,000 miles on her new timing belt water pump cam follower upgraded coils red ones
