DIY Boost / Forced induction / Blower / Turbo / Intercooler on the FB25 2.5L engine featuring 0-60 testing, tuning using EcuFlash / RomRaider. Boost leaks, pressure testing, smoke test, brazing aluminum, intake baffle to quiet supercharger whine, supercharger rebuild, AP SureTrac R160 rear limited slip diff (LSD), Subaru clutch replacement, oil heat exchanger install using sandwich plate, installing a smaller supercharger pulley (65mm to 62mm) for increased MAP / boost psi. Upgraded to a Toyota Previa's SC14 for increased performance and on/off clutch operation. Throttle body as bypass valve and 93mm SCS06 AC pulley for increased boost. Next up, more creative supercharger switching.
