Seriously?

I do not recall many/any complaints about the breaks being bad, just that they fail very quickly when in comes to taking the vehicle to a track. Even then, simple changes have been pointed out that basically alleviates this problem.

Can you point to some specific assertions where people are saying the brakes are categorically bad?

Above 210*, oil temps start having adverse effects on this engine. It begins losing power and my gut tells me some fuel efficiency as well. Continuing to increase oil temps will only amplify the problem. Over the past couple weeks, my engine temps have crept northward of 220* which does not sit well with me. I typically baby my car, but even with my driving style, I still get oil temp spikes up to ~240*. I will be looking into getting an oil cooler put on my car in the coming weeks to alleviate this problem. While an oil cooler may not be a necessity, it will help with peace of mind.

Also, if oil temps are truly not a problem, why do the newer Z's have them then? [EDIT]I left out a not, so went back and fixed it...

Driving fast does not cause the fuel starvation...

It faster than some, slower than others.

How do you know they don't appreciate all these things?

Modern motor oil can survive way more than 240F. They are running warmer and warmer for emission and fuel economy reasons. Of course as the temperature goes up, it does deteriorate quicker. I am with the OP that it is in your head on this one. Also if you look at the ECU fuel settings, it doesn't pull timing from oil temp. It does it only if your engine is so hot that it soaks the air flow meter's temperature sensor, I highly doubt oil temp at 240F is enough to soak your engine by that much unless you are sitting still

I don't think it is pulling timing based on oil temps. I agree with that, but the car still feels and reacts very differently at 190* and 220* for whatever reason. I think it has something to do with the fact that the VVEL system is operated through the use of the oil. When Modshack did his oil cooler write-up back in 2009, he seemed to allude to this when summing up the research he did.

I don't think Modshack linked backed to the actual research items he found but they may be in that thread somewhere.

You have a point and you might well be right, but I am not certain if the difference is as big as people seem to think. I have done laps at 200F/220F/240F and 260F. My datalogger shows no noticeable difference in acceleration between any of the laps with corner exit at the same speed. The difference between them is so small that I am not sure if it does anything on the road. A few HP, I would buy in, but the car isn't going from 330HP to 230HP.

I mean I wish I didn't have to spend $700 on a new oil cooler, but I think Nissan would take care of most of the complains by putting in a oil pressure gauge instead of temperature.

You are probably right swapping the oil temp guage for an oil pressure gauge.

I think the temp difference is more pronounced down low because you have less power available down there. Like 6th gear at 2k RPM's where you would only have maybe 200hp available instead of the full 332hp. I definitely agree it is not losing some 100hp due to oil temp though. We would all be driving lemons then.

As far as the $700 oil cooler, I think I am going to Modshack's route and just build my own except go ahead and get stainless lines and use a 34 row unit instead of the 24 he used.
