Goodmorning gents,

What engine oil should I replace in my VR38DETT and how many litres?

Mobil1 - 0w40 (OEM)?

Willall 10w60?
R35 GTR Track Build - NAGTROC - The Nissan GT-R Owners Club

or any other recommendation?

My car is for track and road use.
I use Motul 5w50 Sport, this is an ester based oil and I have no doubt that Opie Oils may chime in on this one. I use OEM during Winter time as I do not track my car then.

If you do not get your engine oil really hot and are prepared to change it frequently after track days then the OEM oil is OK, you have to remember how much oil dilution takes place when on track due to excess fuelling.

I am changing each 5000km/3000 miles.
Will that be enough on OEM oil?
At what temprature is the engine on track days?
Mine goes around 100 C.

You will be fine with OEM oil based on that change regime and oil temp, I used to get my old R35 into the 105 to 110 zone, I suspect my new 2011 model will run even hotter.

If you are tracking a lot then this would be good, I change my diff oils evey 2 track days regardless, the engine oil as well. If you are going to run the FFL4 then change it at the same time as it is so inexpensive, unless you are going to fit a transmission cooler.

I think I need a mishimoto thermostat as mine OEm does 90 to 95 C the whole day sometimes 100 C

Will this help? New GTR Mishimoto Racing Thermostat R35 09+ | eBay
Mine ran up to 105c which I don't see as an issue with a fully sealed and pressurised system, 85 to 90 would be better and this stat my well help. On tuned builds it will help a bit more but you are also into getting an uprated radiator as well.

I will buy a GTC tune at max 650 hp. I will receive a bridge this saturday so I can work on my car.

Speaking personally, I would not like to see more then 600 carefully tuned HP with stock internals, I am sure plenty will disagree but with track use the loads on the bottom end are magnified considerable considering the duration of the power delivery etc.

I could not really say as I have not run either, I really like the CPR exhaust system but they "detune" that kit so as not to break the con rods etc, which IMHO is a waste. I would first forge the bottom end and whilst out would go with the turbo and intake upgrade along with injectors and leave it at that for track use.
