Blah blah blah....
what do you mean??? how my car engine handles... or a B18b1 engine in general?
Both. You have to know what to improve on before you make the improvements.
Just saying "I want my car to be faster" doesn't really help us help you. There are a million directions to go, and nobody's going to be able to hold your hand. We are here to help with the specifics, and help you make choices. But it's you who needs to figure out what you want to do with the car, and what's gonna make you a happy camper.
