I recently spun the every single bearing in my d16z6 about two weeks ago. My point is that it is at the machine shop and im gonna get it back when i return from my vacation in MeXico. How would go about breaking it in before you just stomp the living ---- out it. How many miles to put on it first and what type or oil (brand viscosity) for the first oil change. All suggestions are appreciated. Thanks

I would talk to the machine shop doing your re-build. They would be able to give you the "break in" specs you need. I'm not saying that no one here would be able to help you, but at least if something goes wrong during the break in, you can use the machine shops word against it. Know what I mean?

I've been rebuilding my engine and I read up on this subject, haynes manual said, drive it for 500 miles at 3000 rpms no hard acceleration, and after 2000 miles its considered fully ready to be abused. not a joke its real. but the thing with me, I will be hooking up my turbo along with the rebuild so I dont know will it workout.

honda says when using new bearings in one of their cars in the engine, start it and idle it for 20 min and hear the engine come up to temp (hear the fans run) then be gentile for the first hundred miles

NAH i just run them at 2500-3000 rpm for about 10-15 minutes. then i take it out and beat the hly living ---- out of it. If the clearances or TQ specs are wrong. itl blow up right away., Itll save you the agony of finding that out 5,000miles after a ew engine install. IF it breaks during a ( break in ) it was broke to start with.

OK, think about this. Do you think race motors are run for 500,1500 or 2000 miles before they race them? No. The reason you run the motor at 2000 RPM to start with is to seat the bearings. I always change the oil right after that. Then you drive the car for a few hundred(about 1 tank of gas)miles taking it easy. Go ahead and take it to redline a few times, but just a few. You do this to make sure you have no leaks or loose bolts. If everything is alright after that you are good to go. Also if is a turbo car keep the boost down as low as you can for the first tank of gas,again just to be safe. Have fun.

I always though the specs that I posted was wierd, but its in black and white, and I dont always listen to hot rod guys but they said it also, but I would with driving out a full tank of gas, but its so your rings will seal, you will have some blowby before broke in.

im a firm believer that you should break the car in the same way you are going to drive it afterwards during the first tank of gas i keep it under 3500 rpm's then i rape the new engine like michael jackson rapes young boys. never had a problem doing this i have almost 60,000 miles on my turbod d16 6-8 psi + a 50 shot occasionally just keep up on maintnace
