The only difference between the turbo's on a 2J is the exhaust housing, the rear turbo doesn't have a REAL wastegate but I'm not going to detail that here. The rear one doesn't work until 4K because thats when the ECU opens the valves and lets it breath. Up to that point the front turbo is capable of supplying enough air alone. Hence the term sequential.
In order to make them a simultaneous setup all you need to do is bolt the exhaust housing off a front turbo to the rear one with the the wastegate actuators off something like a 1J. Then it would behave like a 1J with bigger compressors.... I have an extra ex housing off a front turbo (that will go with the motor) as this was my original plan.
