Perfect for your 400 HP WRX/STi project, the TD05H-18G features the 600CFM performance of the Mitsubishi 18G compressor wheel combined with the quick response of the TD05H turbine wheel. To maximize compressor efficiency, the WRX/STi TD05H-18G utilizes a true TD05H compressor housing with custom actuator mounting in place of the TD05 housing.

The 7cm2 nozzle area turbine housing includes an internal wastegate port and standard wastegate actuator calibrated at 9 PSI. Optional upgrade actuators are available in incremental pressures from 10 PSI to 19 PSI.

Add our waterline kit for just $69.99 (Normally 125.00) to make for a 100% direct bolt on upgrade and other required modification to intake, exhaust, oil and coolant connections for installation.
