I have a 99 s70 glt lpt and was going to upgrade the turbo with a straight flanged 16t turbo. The turbo i have on now is and angled flange, will this turbo work if i us the obx turbo exhaust straight flange down pipe. Also i found a 98 v70r exhaust manifold will it fit on my engine cause i want more flow if im upgrading to a bigger turbo.
