HKS GT2835 PROS Or HKS 3037S
the 1st is internal gate make good power and responds everywhere. 2nd is ext gate depending on which rear housing you get it is responds and makes good power (400 figures)
2835 pros full boost around 3000rpm (18psi), however as mention above 99% of the time when your on the track you are in your power band so lag isn't a issue.
pick your power range, and then your price range.
my setup in my r33 (and i use it for drift is)
hks gt2835 pros (will be replace with a hks 3037s in feb)
pfc, z32, nismo 600cc injectors, splitfire coilpacks, gtr plenum, greddt intercooler, blitz id-3 ebc, hks exhaust etc etc
Also you don't need that much power to drift, get yourself an LSD before you start chasing power
