Cleaned the SR20 injectors this weekend and gained about 1Km per a liter.
I am now averaging 8.7 Liters per 100KM. Previously it was 9.5+. in urban driving.
Also the start-up seems to be allot better and idles smother with allot of water vapor from the exhaust
Well If anybody want to do it you will need the following.
Old Fuel Pump
Container
Wynes Fuel System cleanner
Piping
Wires

Connrect the pump the the fuel rail, Fill the rail with cleaner and try to start the car OR use a AA battary to click the injector open keep primming the fuel rail to keep the pressure up.
Its allot better to have them ultra ultrasonically cleaned but this cost me R40 bucks to do.
