Amen on the "lot's of home work",..I actually bought a car ,.brand new off the show room floor with the style motor I'm using ,..it's got 65,000 miles on it so far and only an oil change every 2k miles has been done to it ( besides the 10th set of tires on the chassis),..still runs like day one,..now you have to understand ,..I use to race cars semi professionally at speeds over 100 mph ,..I am really testing this motors durability,..so it's not just a drive to the store and back ,.. it's 5500 to 6500 rpm coming into a R-100' corner at 90 miles an hour then subject it to 2.5 to 3G side load,..or end load in this case ,..(the motor is mounted in the car sideways) for 5 to 10 seconds at a time depending on the length of the corner,.. that would be like taking a 912 and flying it straight up wide open throttle for 5 to 10 seconds at a time repeatedly..
