Hello to everyone and thank you for taking the time to read my question....I currently put in a brand new ap1 engine into my 2001 s2000. Currently i have 950 miles on the engine and 77,000 miles on the car, and since the engine was put in, I have not exceeded past 5000 rpm. I remember Honda instructing me not to hit V-tec until 500 miles. How much longer should i wait until i can drive the car in its power band? What other strategies could i use to ensure a proper and efficient break-in.

Thanks
Varag



P.S. the car is absolutely stock

*SIGH* ...this keeps coming up again and again....not even a week has gone by since this has last been discussed search is your friend...

Long and short....the guy is trying to con you...he doesn't know what he is talking about and has NO data what so ever to support his claim. If you adhere to his 'advice' you are placing your engine at risk for NO gain. Engine's have been damaged following this 'advice'. Is it worth a $4-5K expense for no performance or reliability gain...

Don't listen to the local village idiot when it comes to break in advice. The manufacture knows what they are doing much more than some 2-bit hack.

 

Whatever you did to your old engine that made it necessary to replace it at 77,000 miles? ........................... Well, don't do it again.

Read your owner's manual again and do what it says like as if your car is new. If you break it following Honda's suggestions, then you did the best you could. If you break it following "the village idiots" way, it's YOUR fault. In the end, it's your bag of nickels.

 

If you already have 950 miles on the new engine, you should be running the piss out of it, of course, after bringing it up to normal operating temperature.
