External Wastegate!
 

Hey I am pretty new to the turbo scene and am redoing my exhaust on my 7mgte swapped 86 and bought a header, it will fit a 40mm to 50mm wastegate and I was just wondering if an aftermarket wastegate bolts right to it or do I need somekind of dumppipe. Any help would be great, Thanks!!

Hopefully its flanged for a common wastegate like hks or tial. You'll need to run a dump tube out the otherside and down under the car.
