Default Turbo LQ4 questions
I知 going for a turbo LQ4 build, and I知 wondering what forged components (if any) I need? My current parts so far are:

GT45 turbo
317 heads
sloppy stage 2 camshaft
pac1218 springs
new bearings all around
stock bore (honed)

Im just wondering if forged pistons are worth it or if the stock pistons can handle boost. I知 wanting to make around 600whp. I am wanting to daily it
