Subaru EG33 engine - 1000 hours

Re: Subaru EG33 breaks the class speed record
Steven, you are correct the intake is a custom one-off that I made. The factory one stood too high and weighs about 12 pounds more. The exhaust is also my own custom build. The gearbox is a...

Re: Subaru EG33 hammers all competitors
The throttle body is original EG33, you can't see it in the photo, it is on the back side of the PSRU (transmission). The black part you see is the original EG33 airflow sensor.

Racers are free to choose any altitude that wish, most of us race at 500 to 2000 AGL.
