Im going to be switching to a T4 setup and im looking to use a Master Power T70. However, i am having trouble deciding between the .68 housing or the .96 housing. Im also curious to see who else is using the T70 set up and the results you got from the turbo. Also advice as to which size to go with. Im looking to make around 550RWHP fairly easily, but have room for more power in the future. I also still want the car to be fairly streetable with good power.
