    How often do you refresh a (street) motor like this? Do you do it primarily as a preventative or because of degradation in performance? If the later, how much degradation? My race car runs a (Lotus) twin cam and gets a check mid season and a rebuild once a year.

    In a challenge (street) engine like this, we use 2 indicators: leakdown & compression and also Km's on motor. On most motors, leakdown and compression starts to get weaker around 9,000 km's, however they can still be competitive. Once the engine reaches close to 12,000 km,s and above, the strength on of the bottom end becomes and issue, and therefore warrants a refresh like this one.

    Thanks. That's a lot of time / miles on the motor between rebuilds. My race motor is torndown about every 1000 miles.

    Those stock pistons have absolutely zero taper to them don't they. Interesting, I wonder what alloy they're using.
