You hhave a 2003 what is their to break in?Did I miss something?

 

I'd call that a damn near direct quote from Vinny Ten.

 

sup zmazing! yeah it pretty much is! good seein you at da meet! awsome time

 

read your manual. it says for longer lasting or better engine dont go past 4rpm and nothing about mph but dont go too fast. if you want to go fast and pass 4rpm go head ur car not mine but majority here wouldnt. and the sales man who sold me my car also has Z and said not to go over 4rpm, warm up car, and get oil change at 1200. he got his on 500 and 1200

 

All depends on who you believe. Nissan itself, or some highly familiar Nissan dealer/mechanic/drag racer, etc?

 

lol.. I am a bad man.. after 100 miles I just drove it crazy.. My Car is gonna break soon.. who cares.. the thing runs like a champ 11K since sept 05.. running it hard.. My buddies and I dissambled it @ 9K to see if anything was wrong cuz one of my friends said it was going to be bad by my driving habits but aha.. he was surprised.. eventhough i like to drive it fast.. i give it's oil change every 800 miles.. new oil filter also... I really take care of her and am glad she's been up to the challenge..

 

in the long run (5+yrs) not short run ( 1yr). some people say just cahnging the oil on time is best for car.

 

+1 My car was delivered to me with 10 miles on it. I was told this was the 10 miles they put on all of them at the Japan test track. Don't know if that is true but it was also delivered with the shift light set at 4000rpm to remind me to take it easy. The dealer told me after 1200 miles here is how you set it back to 6600rpm.

 

huh? really it voids your warranty?

me: Hi Mr. Mechanic, I brought my beloved baby in for maintance

mechanic: Hmm Hmm, well she says you didn't follow the break-in

me: You back stabbing b1tch!

 

Japan test track?

More like a drive from the assembly line to parking-to train-to container-to delivery truck-to dealer parking-to-dealer bay-to pre delivery road test-to you...

Just follow the manual. Be nice to your tranny that also needs to be broken-in... There are way more complaints of notchy/grinding tranny than low power engine...

 

That drive sounds more realistic to me than the track too. Didn't say I believed it. Makes a good story though I've always had a picture in my mind of some Japaneese tech. flogging my Z with the tail out on the track and bringing it back to say "this one go!"
Forgot about the tranny/diff. Good point. I noticed that when my Z had the 10 miles on it delivered to me the drivetrain took some breaking in to mesh all of the gears together. (as a side comparison, even when you rebuild a diff in an R/C car they tell you to drive in slow figure 8's to break in the gears for awhile then take it easy for awhile too.) First day I stalled the Z twice and had to give it gas going up my driveway. A few weeks later it would take off in 1st with less gas and will climb the driveway by itself, in fact sometimes I have to use the brakes a little to slow it while waiting for the door to raise up high enough. There are definately a lot of little things that wear in. I've never heard of anyone having major problems from beating it from day one so I guess that it why there are so many opinions on this. Or people just doen't associate problems at 40,000 miles like valve cover gaskets or grinding trannies to be a product of how you drove the car for the first 1,000 miles. Plus there are many people out there that accumulated all of their car knowledge back in the 70's and some of that stuff may not apply today For all the doubters out there WHY would Nissan tell you to take it easy for the first 1,200 miles if it DIDN'T matter??

 

If break-in matters, then why does my European manual make no mention of a break-in period whatsoever ? Because it doesn't exist, that's why.

Ever seen brand new cars being loaded on/off boats? The guys that do it are not employed by one particular manufacturer, and are paid per delivered unit, they couldn't care less about imaginary break-ins. The cars are started in gear, with no clutch and foot to the floor. I encourage all non-believers to go to a large port and see how it is done.

 

If they started track-testing every single car that left the factory...well, I would still be waiting for mine to arrive!

My shift level came set at 2100 from the factory. The fuel cut-off kicked in at 2600. I drove it home that way from the dealership and then raised the limit to 4000. Funny thing is, it never cut-off fuel after that at 5k above the preset limit. Haven't been able to figure that one out.

 

I drove mine like a wuss for the first 500 miles, then i beat then i ran it quite a bit harder for the rest of the break in. My car makes the most power NA out of all Z's in the 350z club of florida.

 

The setting is for the shift-light only, it doesn't change anything about the fuel cut-off.

 

No, don't redline it. The guy you were talking to was right, at least as far as the new thoughts on break-in procedure are concerned. Don't drive like a jacka**, but you can accelerate more than just feathering the throttle. Keep the revs under about 4,500 rpm, because you don't want excess wear this early. What you do want to do is put a load on your engine, both during acceleration and during compression braking. This puts pressure on your compression rings, making them conform to properly fit your cylinder. Don't get too crazy with it, though, or you could end up losing a % of compression, and you're not going to get that back.

 

Uh..that's what the "haven't been able to figure that one out" part was all about. When I first picked it up from the dealership, the fuel would cut-off at 500 RPM above the factory pre-set limit (2100RPM). Ordinarily, as we all well know, it does not do that...the shifter light just turns solid at 500 above the set limit.

So then why did it do that right from the factory? My guess: Nissan's way of letting the car get babied for the first few miles of its life. Engineers that built it know more than you or I about how it should be broken-in.

 

never drove any of my last few nissan like a grandma. soon as i drove it off the lot i was on it.. my max has over 160,000 miles on it and its a 99 never have had any problems with the engine.still purrs like a kitten.

 

I'm not sure exactly where the 350Z is made but my 2006 Infiniti G35x AWD Sedan was made in the Tochigi Plant in Japan and is surrounded by a test track which they use to test each car that is built there.



from this article

"the finished cars are then started and then wait in line for a dyno and rolling test- they race the cars to over 100mph and then slam on the brakes- quite shocking to someone who babies their new cars! They get the green light and then its driven right out the door. Before a coupe got to the dyno I peeked at the odometer, it already read 3 miles!"


fyi: my G had 4 miles on it when it arrived at the dealer., That was factory->boat->train->truck->dealer->me

 

Thanks konsole, a pic to go with my "story "
Sounded like a fun time. My job takes me to many automotive supplier plants but not acutal assembly lines. That sounds awesome. Best thing I've ever seen is the powertrain plant in Dechard, TN where they make lots of Nissan engines and ship some of them a little north to the assembly line in Smyrna.
