How many miles is the break in?

[Lightweight]

Once I get going on mountain / back road, all thoughts of break in procedures are gone.

I am only thinking about driving this fantastic automobile. It is like who thinks about contraceptives when you are in the moment.

Yes I don't intentionally redline it. My internal redline is not to exceed 5k rpm but...

This is a "flying" Honda. Light nimble like a jet fighter.

I mean it’s a K20. You’re not really gonna hurt it unless you’re VERY deliberately abusing it…like actively trying to destroy it. If you’re doing that, then it’s probably for “likes” from your followers or some other dumb reason. Approach break-in with whatever your priorities are. Want to help ensure the car has a long, problem-free, life? Have fun, but be sensible with it for awhile. Don’t care? YOLO? Well…we could start a whole new thread on how to rapidly break a drivetrain during break-in.

Its nice to be aloof and "in the moment" but while most of us are common laypeople, the metals in fasteners need time for hardening and heat cycles, the consistency of concentricity of pistons rings and cylinders is going to be aided by gradual reduction via pairing with each other. Engines are amazing and this one is a sweet one, so cooling the jets for a week or two is in order.

Why stop the party if it can go on for a long time?? Make that engine last!

事实上，我不确定真正的磨合期是什么。有人说是1000公里，这是正确答案吗？

I once bought a brand new Acura RSX type S and put about 80 miles on it when I got stuck behind a Chevy Nova SS that was just creeping along. I stayed back there for a while but finally put it in 2nd gear and floored it to pass him. He sped up while I was in mid pass but I was committed. As soon as that Vtec kicked in, I easily past him and started bouncing off the rev limiter. It revved up to 8K faster than I expected. It felt good smoking a V8 on my first day. That car was amazingly fast after it was broken in and even moreso after about 50K miles.

Yes! So never rev it over 4,000 rpm if you can help it.

My experience with multiple air and water cooled car and bike engines is just don't lug them around if anything vary the revs and have a go but don't abuse it. Mostly do runs then back off to build back pressure, seat those rings. But, this could be a overhang from my air cooled Harleys.

I just hit 500, and I'm allowing myself to rev above 4,000 in steps, and not while floored.

Regarding brakes, make sure to review the suggestion from the mfg of the pads/rotors. They aren't all the same. So if you upgrade/change them later they might suggest a different procedure.
