Hey People!

I know this has probably been covered but i can't find it, so i have to ask. What is the proper break-in period for the S2k?? How much rev's should you use?

I am picking my car up in a few days and would like to make sure i do it right. For my Integra R, i just took it up to 5,500rpm (just before vtec) for about 1500kms, does that sound right?

Thanks in advance

First of all, make sure you receive a owner's manual and read it thoroughly.

Honda recommends the following for break-in:

- Avoid full-throttle starts and rapid acceleration. Do not exceed 5,500 rpm for the first 600 miles (1,000 km).

- Avoid hard braking. Use moderately for the first 200 miles.

- Do not change the oil until the recommended time or mileage interval shown in the maintenance schedule. This is due to the oil additive from the factory to help with ring seating.


Good luck and welcome!

I would also stress the following. DO NOT, keep constant RPMs or speeds, always vary them the first 1000 kms.

Really! SHOOT! i didn't know that, well it's toooo late now.
In order words, try to avoid h/w for the first 500miles.

And make sure you check the oil at every fill up at the gas station. The s2k WILL burn oil until the valve/rings are seated. I have talked to so many people, and the dealers DO NOT tell you this.

Thanks Guys!

Can anybody tell me why you are not supposed to maintain constant RPMs?

Everybody says don't do it (and I didn't) but I have never heard a rational explanation why

hey RicePimp thanks for the reply.

I had heard some other suspect stuff about complex harmonics within the engine and how wear (including break in wear) happens at in different places of bearings and cylinder walls at different frequencies (RPMs). Constant RPMs caused wear in specific places and unevenly so you wound up with an engine that you thought was run in but was still tight (or loose depending on which bit you are talking about).

Like I say sounds suspect.

I've heard similar things, but always described in very vague terms. I wouldn't be too quick to discredit the effect of harmonics though. An issue with harmonics within the piston rings at no load, high rpm operation was finally identified by Chevy as the culprit with oil burning in the Z06. So there is definately some credibility to that. But that is out of my league. What I posted is about the extent of my knowledge and I just searched around a bit on the web to see if I could find any more, but no luck. I'm sure someone here with some more knowledge might be able to shed some light on this?

Edit: here are a couple links to the forum at z06vette that cover some of this same material:
