ok i just got a cast ebay manifold which comes with studs, and i have a volvo or saab t3 .42 .28 tubo with the weird round flange. i kno i need a flange adapter which im getting from atp but.... the turbo itself is threded too so how do i bolt the turbo/adapter flange to the manifold. do i drill the turbos holes out? anybody encounter this? thanks in advanced!!
