Srry to revive a dead thread, but things have changed a bit in the past 2 years. Does anyone know what the limit of the stock HPFP is with the stock turbo? Will the stock turbo ever out flow what the pump can handle? This assuming you have a stage 2 LPFP already.

Thanks!

OEM or NGK 97506 will work fine, the trick is not gapping so tight or too wide
