Hard driving?

None, but the factory recommended break-in says to keep it under 4k. It's all in the manual. You have read the manual, right?

It's 1k miles.

The manufacturer seems to disagree with you.







I know, engine break-in is one of those subjects that will be debated until the sun burns out.

Well the 370Zs they had at the Nismo Performance Academy were all VERY VERY low mileage... and I don't think anyone was keeping them under 4k or under 100% throttle. I still wonder what happens to those cars when they're done.... "Only one owner, only 1300 miles on the odometer, practically brand new"

As for other break ins. I've had a few performance motors built, and all the engine builders had me do the break in listed in that link that someone posted. I.e. half throttle to half rpm, cool down, three quarters to three quarters rpm, cool down, then full throttle to max rpm and cool down, three times for each part. Haven't had any problem with any of those motors yet, and those guys all built tons of motors.

As for the OP, don't worry about the 7AT. There are many times when I wish I had the auto..namely in traffic. The 7AT also does very well around the track.
