So I started to buy some parts to boost my z6. My power goals are around 220whp.
So far I got these parts.

Skunk2 intake mani.
Arp rod bolts
Arp head studs.
Rebuilt t3/t4 turbo.
Intercooler with 2.5 inch charge piping.

Still deciding on what exhaust mani to use and what size wastegate. I wanna be around the 220whp area. So I'm just wondering if that is possible with my setup and how many lbs would I need to be pushing and would be safe for my motor
