1987-1988 Mazda RX7 S4 Turbocharger upgrade
🚨 Limited Stock – Don’t Miss Out!🚨
REQUIRES CORE - MUST READ INSTRUCTIONS
*S4 turbochargers we need to know how to port the turbine inlet. If you have the switching actuator in the exhaust manifold, the inlet can’t be ported much on the smaller port side. If you have deleted the switching actuator, we can enlarge the smaller port to the size of the larger port. When you print the turbo core instructions just let me know if you have the switching actuator! My personal opinion is if it works leave it!*
