Bought a Second CYM FD RX7!

I’ve been on the hunt to assemble my dream FD… and it just might take a few cars to get there. Stoked to have a rotary this time to play with! http://LZMFG.com

  1. I guarantee you, the car feeling slow/laggy is because of the Charge Control Actuator is sticking.

    The CCA controls a sort of throttle plate inside the Y-pipe, that joins the boosted air in both turbos before it goes into the intercooler.

    When the CCA gets stuck, you can feel the car still has good bottom end power, but after 4500rpm when the second turbo should come in – feels like it takes ages to get to redline.

    The Charge Control Actuator getting stuck is also a bad thing for the secondary turbo, because Mazda designed the FD's sequential system to have the secondary turbo operate "in surge" under low RPM and at WOT so that it has power all through the RPM range.

    I had this issue on a few FD's I've owned and the fix is to remove the Y-pipe and disassemble the CCA and clean it all up and also look at the vacuum solenoid that controls it, which sits under the intake manifold. I've bought a lot of FD's for cheap because a lot of people thought their FD had a blown turbo or motor because it felt lazy – turns out it just needs some TLC and addressing the CCA.

  2. I’ll be honest I would have kept the shell in case the other one gets a lot of damage or frame damage or burned. Hoping it don’t happen tho
