The F20/F22 motors look right at home in the 2002 engine bay. As BMW never produced a modern high revving naturally aspirated I4 M engine the S2000's engines make pretty good swap candidates that maintain the spirit of the E30 M3 S14 motor.
This particular owner decided that the 2.2 liter 8200+ rpm screamer was not enough on its own and added a big top mount turbo for good measure.
What are the specs? How much power? What fuel? What turbo? Who did the tuning? All good questions. Hopefully we eventually get some answers.
A badass swap regardless.
