Naturally Aspirated is the club for engines that make their power the old way. A Swift 1.2, a Civic 1.8, a Mustang V8 and a 911 GT3 have one thing in common: the throttle is connected to something, and the rev counter is the point.
For verified owners of any car with a naturally aspirated engine. Registration and an ownership photo.
What happens here: intake, header and exhaust threads with dyno sheets, oil choice for engines that live near the redline, cooling at sustained revs, valve and timing service intervals, and drives where the roads reward a car that has to be worked.
