Earlier this week Turbosmart announced their brand new Internal Wastegate Actuator (part #TS-0605-1072) for the VF48 & VF52 turbos. The VF52 Turbo is found in the 09-12 WRX & the VF48 Turbo is found in the 08-12 STi.
The Internal Wastegate Actuator provides better turbo response and greater sensitivity when managing boost pressures. Each IWG is adjustable with several spring options and packaged in a kit form so they can be fitted as a direct bolt-on replacement for the factory part. The kit features a silicone diaphragm with Nomex reinforcement to withstand high temperatures and stainless steel rods and connecting clevis for corrosion resistance. Also the actuator has a locking collar design cap allows for quick spring changes. The spring range is 3 to 26 psi.
