After 12 months of collecting engine parts and prepping a spare RB26 for the rebuild, this is the end result. And boy was it worth it.
At the dyno, my car put out 500.84 PS (493 whp) at 1.6 bar, displaying a good power band and a very healthy max torque of 56.24 kgm (551.15 N·m of torque). Full boost at 4000 rpm. That's the equivalent of how much power and torque a BMW E60 M5's 5.0L V10 engine makes when the "M" power button is switched on (Power: 507 PS; 500 bhp at 7750 rpm / Torque: 520 N·m at 6100 rpm).
Loving my 'new' R33 GT-R :).
So anyway folks, thank you so much for following my rebuild and for your continued support.
I'd like to wish our Muslim readers a Selamat Hari Raya and Maaf Zahir dan Batin. To everyone, please drive safe during this festive period and do take care.

The rebuild is going well and I've sent in my Tomei camshafts + Pulleys and a N1 Water Pump in for the final stage of the project. Looking forward to how the cams perform as not only will they improve response and overall performance but the poncams will also have a positive affect on the R33 GTR's exhaust sound.
And why Tomei? Tomei Poncam camshafts are designed as a "drop in application", so no dialling in required as the nock-pin has been pre-set. The Poncams are also designed to work with the standard valve springs and offer the best drop in performance gain for both street and track use. No machining is required at all.
Tomei manufactures several camshafts for the RB26 engine, the most mild being the Poncams. Designed as an upgrade when compared to stock cams, the Poncams fit all generations of the RB26 engine (R32, R33 and R34), and come in three types, Type A, Type B, and Type R. The differences between the Type A and Type B Poncams are limited, with the Type B version featuring 260° of lift on the exhaust, compared to 252°. This slight increase in duration means more air can enter the cylinders at higher RPM. The downside to additional duration is that low end power is sacrificed, as the turbochargers typically can not move enough air at lower engine speeds. The Type R Poncams were designed by Tomei to cater to those who wish to remain "street legal" by Japanese standards. This means decreased duration for better emissions, as well as compatibility with stock or aftermarket catalytic converters.
Type A camshafts are suitable for engines that will be using stock or larger bolt on turbochargers. Type B camshafts are for engines that will be running N1 turbo chargers or full aftermarket turbo kits. The Type R camshafts should only be used when a car retains the factory catalytic converter, or when you wish to upgrade to an aftermarket catalytic converter.

Excerpt from nengun.com about the Tomei Poncams:
Tomei presents the popular poncams. Generally, engine tuning is to modify the torque characteristic of engine by changing cam duration timing and height of the cam lift, so as to gaining maximum torque and horse power. However, when tuning the engine strictly, it should be carried out with the idea of securing effective area of the valve not only by duration timing and height of the cam lift, but also by through improvement of its intake efficiency. High valve lift allows huge amount of air to flow in, yet it mechanically damages the system and gains friction loss. Also, wide cam duration will deriver great power at high RPM, but it gives rough engine character at low RPM too. Tomei have worked to get an ideal well-balanced profile of camshaft and succeeded to give it 1.3 to 1.5 times more effective area than regular camshafts.
Apologies for the lack of updates but its been a busy month for me and I've been waiting on a particular part to arrive. In fact, its the last piece of the engine rebuild jigsaw puzzle. I'm referring to conrods as it was the only other forged item that I wanted for this rebuild. Lo and behold the official spiel (summary courtesy of Nengun):
Usually, to give con-rod buckling strength and light weight character at the same time, H-beam or I-beam profile is applied. Tomei have applied a H-beam profile for the connecting rod for NISSAN RB, SR, CA, VG engines and succeeded in gaining high buckling strength while reducing the weight. Tomei produces con-rod's using a forging mold with the main bearing hole in its large end, so the 'metal flow' runs along con-rod's entire body. And with a use of special materials, they have succeeded in producing con-rods with extreme intensity and durability.
Naturally, I got standard RB26 stroke conrods as I'm not stroking the spare engine. Thanks to my good friend Glenn Trollope of Chasers Motorworks Melbourne (good luck at the World Time Attack dude!), I was able to source the conrods in record time.
So that ends this update as the crank is being balanced but I'm hoping the engine will be ready before the end of May. Theres also the Nismo bearings that need to be installed and those had arrived sometime last month, courtesy of a fellow Skyline owner (thanks Nain!).
Here are the bearings:
Can't wait for all the parts to come together. Watch this space.
