I had to do the cam break-in 20min at 2,500rpm.
Then I changed the oil and filter.
Then I took the car for a 1hr drive breaking in the rings just like I did on the racebike.
First 10min, alternate 50% throttle and overrun (vacuum coast-down), up to 5k. Yeah I felt like a dork hobby-horsing down the thoroughfare, screw 'em I was still driving a Turbo.
Next 10min, alternate 70% throttle and overrun.
After that, give'er the berries for successive pulls and make sure to let it coast down under full vacuum. I didn't rev it out all the way but I let it get several successive 3-5k 3rd gear pulls to get the pistons and rings good and hot.
I knew my rings were bedded in in 200 miles because I had lots of engine braking again, and cold startup only gave a puff of smoke. I passed CA smog 375 miles after rebuild.
