I'm just a bit curious. I was looking for SR20DET bottom end parts and I bumped into a link of a Tomei SR20DET complete motor. I was very shocked at it's insane price tag of $20K. I wanted to know what makes this motor different, better, or more beneficial than one of our own garage builds. I mean 20K into a motor??? Is it made of special material from the deepest parts of earth or wtf?
