You cant rev the car past 5XXXrpm in neutral. You guys ever notice this? Might be a built in limiter to protect the engine.

I went with the factory ester oil for my oil change. I wanted to see if the oil cooler does its job without worrying about whether the oil had something to do with it.

From what my tech said, nothing will happen if you switch to syn, the only problem is that the valvetrain will be a lot louder. You are going to get clicking...

Did you verify that in your car or are you echoing the comment from the other thread ? If you verified, have you tried it when shifting from 1st to 2nd ?... ie I'd understand if you were just sitting there standstill with clutch pushed in it might limit to 5K... I'd guess that nissan did this to avoid having folks pop the clutch at 7k in 1st gear - would take a toll on the drivetrain and drive warranty costs... but something tells me that between upshifts the revs aren't limited in this way... still depending on someone else to verify - car in shop

Yeah I noticed this pretty early on. Clearly the car must be capable of being higher in neutral when driving though, or that would totally screw up some shifting scenarios. I haven't yet tried putting my 7AT in neutral at freeway speeds and seeing if the limit is still there. Those kinds of behaviors might be very different between 7AT and 6MT though.

You can if you press the clutch in. I found this out when I was making one of the initial sound clips for my exhaust. And I seem to recall that it limited the revs to 4500, not 5000, if I didn't press the clutch in.

Edit: I just remembered that in addition to pressing the clutch in, I had to slip it into 1st gear in order to rev past 5k (or 4.5k or whatever it was). So technically you are correct, RCZ. You can't rev past 5k in N.

I tested the "revving in neutral" thing on the freeway last night. In neutral rolling at highway speeds, 7AT will rev well past the 5k mark (I didn't try to hit the 7.5 limiter though). So the 5k limit on 7AT must be triggered by being in park, or being at low/zero speed, one of the two.

Also, today I removed my spare and subwoofer (radio actually sounds ok without it, to me), and removed the XM and Voice/Bluetooth modules. I left all the carpeting and plastic in afterwards. No pics, sorry My car is Touring w/o Nav, which is "Bose without Navigation" in the Service Manual. The removed peices are 7, 8, and 9 on this diagram:



The stock head unit responded fine to the changes. The voice buttons on the steering wheel and the SAT button on the radio now just do nothing, there are no wierd errors or anything.


I can slightly feel that the backend got relatively lighter from this, but it's not too bad, since my bag of tools and emergency equipment (which I had behind the passenger seat before) was pretty hefty and made up for some of the lost weight.

The spot I removed those units from looks like a great place for either battery relocation or to install a Magden performance computer. Although on the other hand, mounting them further to the rear (sub/spare) area will help with weight distribution more.
