I would like to know where the ceiling of the stock turbo is. At a certain point, it's out of it's efficiency range and it's working too hard.
I am thinking 300whp will be no problem with supporting mods(downpipe, intercooler, exhaust, stage 2 tune). But will the stock turbo support 320whp, 340whp?
