Hooking up rods and you can pistons
Centered on Subaru, higher power situation toward linking pole bolts allowed highest pressure is encountered in the cylinders. In addition, new linking rod bearings were made out-of an excellent copper-situated metal.
The new FA20E and you can FA20F motors is know to have throw aluminum pistons. A great ‘hybrid’ layer was applied to the new piston dresses to minimize friction, since the the upper pistons have a top contour that have a superficial dish-instance cavity to possess secure combustion toward start-upwards.
Garrett MGT2259S turbocharger
The FA20E and you will FA20F motors was fitted with a twin-search Garrett MGT2259S turbocharger which, according to Subaru, try organized in system having shorter warm-up of one’s catalytic converter, top throttle impulse and you can a more lightweight fatigue program.
