No, no... the dual port (actually, I think it might be triple port - two nipples on one of the diaphragms) is STOCK on StarQuest turbos. I just don't think it bolts up to the 14Bs we have (or anything else with DSM clocking).

From turbochargers.com (Starion/Conquest 14G):




EDIT: it looks like 45-degrees clocking is enough to fix it (see DSM 16G above), assuming the bosses on the compressor housing have the same spacing as the actuator. That might IMPROVE the direction of the compressor outlet, but might also put the wg actuator into the firewall...

If a Starquest compressor housing used a DSM wasteagate actuator (with custom clocking), it looks like J-pipes (and outlet adaptors) wouldn't be necessary at all.
