How soon is too soon?!

GeauxTigers1

Hey guys!

Well still just sitting here waiting for 3/3 to come for the delivery of the new Z! While I'm dreaming about it, I started to wonder two things:

Is there really a break in period on these things? As in should I keep it under a certain rpm for a certain amount of miles and ease her in? I REALLY want to get on her a bit day 1 just out of pure excitement but can hold back if I need to!

Second, how long do people wait before putting FI on the Z and void out the warranty? I wanted to give that cushion to make sure there are no manufacturer defects of course that I typically would be able to bring her right in to get fixed. Whereas the second that turbo hits the motor that's not longer an option. I had a 2009 GTM TT and want to go AAM sooner rather than later! Thanks guys! Can't wait to be a part of the family again!

I believe per the instructions there is a 1,500 mile break in but really who follows that? I started running the RPMs around 600 miles and going to redline by 1,000.

Also, I slapped on a GTM stage 1 SC kit at 19,000 miles and am now at 90,000 miles.
Warranty is 50-50, if you have a good dealership you are good with they will still honor parts of the warranty. Say a window motor goes they should replace it under warranty, but say you blow your clutch out then that is a tough call. Some will help out, maybe try to claim CSC failure and cover it or cover a portion, while others will just tell you to pay them to fix it.

Owners manual states keep rpms below 4000 for 1,200 miles.

Don't use cruise control during that time period and make sure you vary gears if on extended trips at the same speed. Also no hard braking for the first 200 miles.

As for FI. I would wait until the motor is properly broken in and wear metals start to drop off in your oil sample. Send all your oil changes to Black Stone and when they report the motor is at normal wear metals add boost.

Nice thanks for the info guys! The guy who will be working on the car mentions first oil change. That way they can do those samples and by then she should be good to go. Also doing some down shift/engine braking instead of using the brakes. Nothing ferocious just giving her a little pressure here and there. Heard stay off the freeways as much as you can at first to keep shifting through those gears so nice to hear a lot of the same that you just advised.

Damnitt next oil change seems like a long time! Whatever, more exuse to drive her around everywhere instead of sitting in the garage

Not gonna lie when I was at 200 miles I went from Houston to Austin a couple times in a month, varies speeds, gears, etc to just add miles. Had friends in Austin to visit and was nice, but was a good excuse to get some miles on the car.

I did circles around 610 and the beltway

I kept mine below 4kRPM during the first 1,500 miles. But that's just me.

I drove mine like I stole it as soon as I pulled out of the dealership.

My new Mustang has less than 500 miles on it and a Whipple 2.9 is on the way! I will probably install it with my first oil change.

I put a supercharger in at 11k. I don't know the specifics but consider your warranty void. Just enjoy the car!

GeauxTigers1

Like your line of thinking. I may follow that. Just in case she is part of the family! Gotta treat her right!

Same here, boosted it at about ~8k miles on the clock.
1 year, another 8k miles, over 600hp/550hp, driving it like a madman....it's perfectly fine (my engine).

I bought my car with 2 miles on it...has never given me an issue yet! Nissan did a few things right on this one

With most modern engines, the break-in period is less than 1000 miles. During that period you want to take it a little easy - don't baby it but don't push it real hard very often. As others have mentioned, varying the speed/load will help.

Monitoring the oil, as per jwick, is the best way to tell the condition of the engine. For many people this is overkill but you sound like you are picky enough that it would give you some peace of mind.

As mentioned above, the brakes need a little breaking in, too.

Have fun!

Oddly enough my best oil sample to date came after my first post-turbo oil change. Blackstone even commented that the car must love the extra power

no break-in on my engine and started tracking it right away. Now at 23k with about 17-18k on track and no issues, plus one of the highest hp NA motors on the forum at 342 rwhp. Break it in like you are going to drive it.

I strictly followed the break-in period instructions when I bought my Z new....when they replaced the engine under warranty at 40K miles I strictly followed them again.
