I just read your thread a bit. I haven't built an engine so if you want to discount what I say then go for it.


How did you break in your engine, you said you were idling it for a while as you made tuning adjustments? Was this before you did a proper run-in (dyno or hard driving)?

Breaking the engine in should be mostly done within 15-30min of hard driving but you're supposed to run a mineral oil for the first 1,500-2,500 KMs as the last part (about 10%) of the break-in happens more slowly over this period of time. First oil change after that first short run.

It will blow a fair bit of smoke before the rings are broken in properly. Should mostly stop after the initial 15-30min.

New B18C2 compressing well should put out about 220-240psi, right? That's the impression I'm under but I have no idea what CR you have (didn't read it all).

Personally I'd go by the specs recommended by product manufacturers.

I believe (don't quote me) that you're supposed to run the car preferably rich rather than lean during break-in.


My tip (noob) would be to run it in on a dyno. Tow it there, run it in, change oil, drive away.
