new turbo.. help..

[mr. silvia]

hey i am about to install a sc50 turbo on my redtop sr.. i have a walbro fuel pump, fmic, 3 inch cat back, 660cc injectors, n62 maf, and a enthalpy tune ecu.. i was wondering what would be a safe boost level to set my boost controller? also what spark plugs i should run and at what gap to gap them? thanks

I'd keep your boost around 12-13 psi at least untill you get a better HeadGasket and perhaps some head studs....7 for your spark plug heat range, and close the gap up to .028"

i do have a metal headgasket, but stock head bolts..
