I have read through most of this forum and read many bad things about Hayes Rotary. I bought a 1993 RX7 that they did a T78 conversion on. I am looking for english instructions to insure that they did everything correctly. Also, I have a Profec B boost controller and I can't get the car to boost over 10 Ibs. I verified that the settings on the back are correct I ran the out to the tip of the wastegate, the in to the turbo piping, and the inner connection of the wastegate to the intake mannifold (a vacum line that was capped off). I have a Greddy Type R Blow off valve that is connected to the piping right before the turbo and a Greddy wastegate. I something hooked up wrong or do I need to purchase different springs? Any help would be much appreciated.
