Engine rebuild every 1k miles at £4k a pop 
Aaaahhhh i would have stuck with the GT-R . You may be able to reverse the deal ! It might not be too late !!!! 
Merry Christmas

So can you could run one of those engines on the road for tens of thousands of miles between rebuilds?
If that's the case it makes more sense to me, I would suspect if I hammered even one of the best engines anyone on Scoobynet owns in the top level of competition it would expire well before 1500km...

Domino is spot on they dont change them after miles but hrs run 
But when they sell them they sell with how many miles they have done.
Transmission: 150kms
Turbo: 470kms Rear Diff: 40kms
Fuel Box: 470kms
Exe-TC Dampers: 40kms
Hubs & D/Shafts: 200kms
ect ect

I have never heard of anyone lifing there engines in hours , only mileage , and then it's stage mileage not including road mileage , I have been told by Melvyn Evans , Graham Sweet , and autosportif that I should get 1000 stage miles between rebuilds of engine box and diffs , unless something breaks , which does happen rallying .
The only thing I have been told will need looking at on a regular basis is shimming the carbon clutch.
Here is mine in its current state

Nice GTR graham, i like how it stands out from other GTRs
I was wondering do you need to put V-power in these or can it be normal unleaded?

cheers guys! very happy with it, changes the style of the car quite a bit for the better IMO
I run it on vpower, but the ECUTek software allows me to change the fuel map and boost on the fly. 3 different fuel maps and the boost is completely adjustable from 0.5-1.5/7 bar (not sure on the high boost).

I just love the GTR too much
It is so easy to get carried away with modding the GTRs, tried to keep it simple, clean and purposeful. So not too much more planned:-*2012 suspension (already have these, just waiting for fitting) - slightly better comfort and race mode
*custom rear spoiler (starts being made with next service)
*track wheels
*brakes - when the stock ones die
After the above, its down to safety and weight:-
*lightweight seats
*remove the rear seats
*carpet over
*maybe a light TI exhaust
*maybe a rear half rollcage (not sure on this one just yet)

Around 600bhp is my guess... downpipes, panel filters and injectors would be 620-630bhp.
Thats pretty much as far as you can go before opening the engine up. You can do turbos, which make more BHP, but they cannot make more torque. Limited due to rods.

Depends on the "whole exhaust" piece... the main gain is removing the cats. There are cats in the downpipes and the ypipe. Most exhaust systems do not include the downpipes.

Turbos for more power after that, but you want to think about the conrods, gearbox circuits/baskets/clutches for more torque reliably.
Personally, just a map is enough for me on a 2009, the car is still balanced and reliable and you really have to think abut the road surface and conditions when using the torque.

Did you go ECUTEK?

You can get turbos done without the engine and run 650-700bhp, but the torque is limited to 600-620, about the same as my car. Dont really see a point to this turbo upgrade.... costs a fair bit and only bhp figures, doubt it will give much on the track or drag strip.

After stage 4 (stage 4.25 with downpipes) it starts to cost a fortune to get decent power upgrades.

No... will max out the injectors around 600 and Im not sure about the intakes. I have K&N panel filters and they limiting me now, but I am happy with my power level.

The stock turbo go flat after 5/5.5k, after market units keep the car gunning through the redline
also there's just generally more area under the power curves which makes for a use able road car (admit that the stock car is also more than ample for 99% of applications!)

Cobb. Totally standard but very carefully custom mapped. Dyno figures are nonsense, but my map on a car with a midpipe did 620. Midpipe adds about 10, but the dyno adds about 40!

Tyres have become cheaper and there are aftermarket brake discs and pads too.
I have adopted the 2011- schedule on my 2009 and only do 5000 miles a year, so it sees the dealer for an annual oil change for which they charge me £150 and I supply the oil myself, they stamp the book and last time gave a year's Nissan recovery. I had the trans oil changed by the dealer at 18 months when it only had 9000 miles but have just changed it myself 3 years later (old stuff looked like new though but was aftermarket and a bit jerky when cold), Pentosin FFL-R designed for the GT-R was under £200. I am not changing the front and rear diff oils after 13000 miles of road use since they were last done. The secondary air filter looked clean and only squirts air into the exhaust when cold, so I did not replace it.
Things like sparks, air filter, coolant, brake fluid are similar in frequency to most other cars, and overall, engine oil once a year and trans oil every three isn't a killer. Depreciation has been very kind, but mine is a long term keeper. I don't consider I am scrimping on servicing, just doing it a bit more sensibly considering its mileage which the official schedule doesn't allow for on the early cars, but I am not selling it and it is out of warranty, so my only responsibility is to myself.
