i just put my motor back together last weekend. wiseco's 20 over, twisted grimes did my machine work

when i was ready to start it: i put in non detergant straight 30 weight oil.
disconnected cam angle sensor and cranked it for 15-20 seconds two times to initially prime oil in it. connected my cas back up

started the car, let it idle for 2 minutes till my lifter's pumped up. held it at 1800 rpm for 10 minutes until my coolant reached operating temperature. cut the car off and topped off my antifreeze after it burped, changed the oil and filter.

put in rotella t 15w-40 drove to the gas station. then basically worked my way in 2nd 3rd & 4th gear from 30% throttle 3k rpm, to 60% throttle 5k rpm, then 100% throttle to redline within the first 20 miles (all on lowest possible boost which was 8psi). then continued to drive for an hour and a half gettin on it whenever possible. didn't get any blow by whatsoever.

200 miles later, i changed the oil and filter again, more rotella t 15w-40 (i'm gonna continue to use it, i'm emissions excempt) plus the zddp (zinc diaphosphate some shit) that rotella t has is great for performance engines. i also changed my plugs back to the iridium kind i always run and i checked compression just to get an idea of how i was doing on my break in. 170psi on all 6 cylinders with 5 seconds of cranking on each, i'm sure it'd be a little more but considering my first motor was 135psi across the board and my second motor was 150 across the board i was excited =]

so now i'm 500-600 miles into it, still beating it's ass on 8psi, no problems, tomorrow i'm going to tune low and high boost. before i go tune i'm gonna change the oil one more time.

basically the significance was, the people saying be easy on it, or be at one constant speed and don't push it at first, ARE WRONG. from what i've found you're hone is only going to file the compression rings REALLY WELL for the first 20-60 miles, therefore within that window, it's crucial to work your way to 100% throttle / redline within that window.

this thread really helped me. it it absolutely does make sense. granted it goes against "i just spent a shit load on this motor i don't wanna break it already" but you gotta get on it now if you wanna get on it later.
