Start with new check valves. Change the ones colored black and green on this diagram: http://www.davidgeesaman.com/rx7/93v...lor.edited.jpg

Sounds like your second turbo is not coming on line ... you gotta find the problem with the turbo actuator solenoids or check valves as mentioned before. Good luck, what you are about to encounter is the reason many go non-seq.
