how long should I take it easy (under 4000 rpm) fully built LS motor, ITR pistons, full race head, ect. I was told 1000 is that about right?

THanks.

I'd say 1,500 miles. Then get an oil change to full synthetic motor oil, then beat the **** out of the motor.

 

would a 7,000 RPM after 500 miles just a few times hurt it?

 

Haahaha Its hard to keep your car under redline when you have a built motor huh? I redlined it couple times when I got my motor rebuilt as well. Couple times is ok, but often is not good. TRY to keep it under 4K. and WAIT until you hit 1,500 miles, and I know its hard though lol. Good luck!

 

im going to go threw the torture of not being able to rev my ls motor once its done too, it was hard enough doin 400 on my clutch and flywheel, i dont know how im goin to do it.

 

yes, its VERY tempting. I dont know how much longer I can hold out!!!!!

I guess my REAL question is this; I have 500 miles on it so far, real easy driving. I want to know if I could redline 2 gears like ONCE (ex. Civic SI destruction) until I get to 1000 miles, or would that competely defeat the purpose?

Go to crvtec.com and read up on what they have to say...

Just laugh at the SI's when they pull up. Like it isn't even worth the gas to play with them.....I would hold off until the 1,500 or you are going to loose what you will have if you don't.

 

Use 0-30, or 5-30, or 10-30 motor oil and a Honda filter. Do NOT use synthetic motor oil for break in. Make sure the fluid levels are where they should be.

Start it up and keep the engine at 2500 -3000 rpm for about 20 minutes. Make sure there are no leaks, or mechanical problems. The only idling will be for setting the timing.

Before doing the schedule, remember that running the engine at steady rpm (like cruising on the freeway) is not good for break-in.

0-200 miles. Try to keep the highest rpm under 3000 rpm. Every 15-20 miles, zing the engine to 4500 rpm in first and occasionally in second gear.

200-400 miles. Try to keep the revs limited to 3500 rpm. Raise the "zing" rpm to 5500 with the same frequency as above.

400-600 miles. Go to 4000 rpm for driving limit. Raise the "zing" to 6000 - 6500 rpm and include 3rd gear pulls, same frequency.

600-800 miles. 4500 rpm driving limit. "Zing" it to 7000+ rpm and include partial 4th gear pulls.

800-1K miles. 5000 rpm limit with "zing" to 7500+ with some pulls all the way through 4th and partial fifth gear pulls.

Now, don't misunderstand me on the zings. You don't HAVE to scream the engine religeously at the prescribed intervals. If you don't have the space to run the engine up in the selected gears, don't do it. Just know that you can, and IF the opportunity comes around lay into it. Don't over-do the procedure.

I recommend that the oil be changed at the 1K mile marker. If the plugs are looking good and if the compression's (and leak down numbers) good, switch to Mobil 1 for life. Use either 0-30, or 10-30. After the oil change, you might want to reset the valves and from that point on, drive it the way you'd normally run it.

 

Just reminding you... Don't go to heavy throttle in a high gear to keep it under 4000 either . None of that WOT in 5th gear at 40 mph stuff...

Actually that's NEVER good for a car, whether you're breaking it in or not.
