FD Mazda RX-7 Sequential Turbos Troubleshooting - Pt.2 (Turbo Control Solenoids & Silicone Hoses)

In this video, we test the wastegate solenoids, pre-control solenoids, and the secondary turbo control solenoids on our 1994 Mazda RX-7 FD with a 13B rotary engine. Our goal is to find our secondary boost issue. During our disassembly and diagnosing, we found a few hoses that need to be replaced and a possible faulty solenoid. #mazda #mazdarx7 #rx7 #mazdarx7fd #rx7fd #driverstherapy
