Either way. At high boost on E85 it shouldn't matter much. The AMS Evo kits do it like option #2 using the 5-bolt Ford style T3 exhaust housing with an O2 housing mounted wastegate. Their kit doesn't control boost worth a crap when you get into the bigger turbos like the 6262 and 6765. Often you have to set the revlimiter low on pump gas because the boost creep is so bad and if you try to pull timing to get rid of the knock from boost creep then it boost creeps even worse.
