2018 Subaru WRX
Category : Uncategorized
Just another week in paradise and this time were we tasked with a little maintenance, cleaning and modding. This engine desperately needed some deep cleaning and with these FA20DIT engine, they tend to clog up pretty quick.
We suggested some walnut blasting to the valve areas and deep cleaning to the intake manifold, throttle body and lower tumbler areas.
In the end we were pleasantly surprised as well as the client on how responsive the engine is and the added torque from the upgrades, cleaning and calibration made a huge difference.
Graphs above are at 20psi in 4th gear and the ambient temps on the day were 67F, 45% humidity and 30.13 baro.
