I have an RX7 1993 R1, and I just finished installing an engine made at Atkins, with 3mm apex seals, and stage two street porting. Also I installed a turbo Kit T78. All turbo solenoids were eliminated as well as the double throttle ,metering oil pump (works with premix), egr, acv, aws. I have had a lot of problems just to start the engine but finally it started. The engine works fine in idle, as well as with very gentle acceleration. But, whenever I try to drive and try to accelerate, the car fails and stalls. The air/fuel meter reads lean mix when the car stalls. Then I reconnected the solenoids to no avail. I checked the fuel pump following Mazda guidelines and the pump is putting out around 85 psi and 35 psi with fuel regulator on and 40 psi with fuel regulator off (all the time), the injectors were serviced (all of them). I presume that the secondary injectors are not working. How can I check this?. Can somebody tell me if the secondary injectors activate after the primary ones? Please help. Have mercy on me!!!!!!.
