SSilver50

I am new to owning Audis and have just bought a 2008 A3 with a 2.0 L engine with manual transmission. My biggest concern is that The car is running on about half of its cylinders and needs an engine replacement. This is going to be a car that I drive about three times a week and I can occasionally take out on the track. Are there any recommended engines for this car. I would still really like to keep it manual if that’s possible.
