Try doing a search - there's a million threads on this (particularly in General Maintenance and Forced Induction)
For the record, I use Elf Excellium 5W-40 Full Synthetic
In saying that, I think a fair few people on here use Motul 300V Chrono, 8100 Excess or 4100 Turbolight - there's many to choose from that will do the job. Do the search and figure out what suits you best.
I guess it comes down to how much you want to pay, how modded your car is and how you use your car (i.e sunday driver, daily commuter or weekend warrior for example).
