10 psi??
Well two questions actually what supporting mods would i need to run 10psi safely on a mostly stock s4 turbo ii? Boost is still stock at 6.5 and i would like to raise it to 10.
Right now i have a racing beat dual exhaust,s5 turbo, and rb dwn pipe, 550 injectors, still have omp, running 1:1 premix and rats nest has been removed.
Second question i would like to take her to some Drift events but would like to upgrade the clutch and flywheel any recommendations?

"build your engine" is not really advice and not necessary.
Properly maintained and low to medium miles on the keg and you are probably just fine.
An upgraded fuel pump wouldn't hurt with an adjustable FPR and a wideband 02 for extra safety. But on a stock ecu you will be limited. At 10psi you might want to consider switching to 1000cc injectors and a standalone ecu. Sprint RE is what I am looking at running with similar to same mods on my s5 tii to get that extra bit of go out of her.
oh, and a boost gauge if you do not already have one. I think the waste gate on an s4 turbo needs to be modified? someone else could chime in on that.
