Spare Engine Rebuild Update: Tomei Poncams

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.

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.

Spare Engine Rebuild Update - Tomei Forged H-Beam Conrods

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.
