APS Bolt-On Turbos for 02-07 WRX & 04-09 STi
APS WRX/STi Turbochargers
Finally, a range of affordable high performance journal bearing direct replacement turbochargers that have been specifically designed for the by the Subaru performance specialists - APS. APS has engineered a series of proprietary turbochargers from the ground up to match the exact requirements of high performance Subaru 2.0L and 2.5L engines. The APS SS Series turbochargers are designed for fast spool-up to deliver crisp turbocharger response and smooth torque delivery. Best of all, SS turbochargers are complete bolt-on for 02-07 WRX and 04-09 STi models which makes for a clean and hassle free installation. The APS SS45 and SS42 turbochargers are both designed identical compressor design, dimensions and flow characteristics. The difference is in the turbine housings - which in the case of the SS45 turbocharger, a larger 8cm exhaust housing results in higher flow capacity for the larger 2.5L engines. All APS SS turbochargers for the 02-07 WRX & 04-09 STi require an upgraded fuel pump, larger fuel injectors and a reflash or custom ECU tune. To achieve quoted horsepower numbers, upgrading your intercooler, intake and exhaust system are also necessary. For more questions on supporting modifications, please call 1-888-JSC-SPEED.
