Pic 1: Tomei Poncams

I have for sale a set of Tomei Poncams taken out from a BNR34. The camshafts are meant only for the RB26DETT and will fit BNR32, BCNR33 and BNR34 Skylines.

These are designed to best suit the stock or larger bolt on turbos for optimum performance balance of low to mid range torque.

The camshaft specifications are as follows:-
Duration (Intake) - 260°
Duration (Exhaust) - 260°
Lift (Intake) - 9.15mm
Lift (Exhaust) - 9.15mm
Intake Valve - 110°
Exhaust Valve - 115°
Intake V- Clearance - 0.45mm
Exhaust V- Clearance - 0.38mm

With the setup, it is recommend that that the stock catalytic converter to be removed and replaced with a straight pipe (damn how environmentally incorrect is that?!?) or a sports catalytic converter be installed in place. The stock turbines can remain but larger bolt on type turbine are also ok.

Shoot me an email (eujin[at]hotmail[dot]com) if you're interested. :)

Tomei Fuel Pressure Regulator Type S

The factory ER34 fuel pressure regulator (FPR) is great for stock to mild tuning, but it is not capable of increased fuel demands for higher horsepower applications especially since a higher output fuel pump is installed.

Errr ...... yes more horsy power is indeed in the works for the ER34.

There are many fuel pressure regulators in the market from Sard, Nismo to Malpassi but I settled on the Tomei because it's pretty new in the market and at the moment there are no copy versions. Fake units of Sard fuel pressure regulator are now everywhere in the market and you wouldn't want to be fooling around with matters concerning highly flammable fuel!

Pic 3: Tomei Fuel Pressure Regulator Type S

Tomei fuel pressure regulator (Part No. 185001) is a rising rate regulator and have 2 versions; the Type S and the Type L. Basically a smaller and a larger version. The Type S FPR is recommended by Tomei for general tuning setups (Boost-Up/Bolt-On Turbo). The Type L FPR is recommended for Higher Flow, High Power, High Boost setups. Thus in my case, I suppose a Type S will suffice. :)

I must say that the FPR looked very 'pretty' compared to the offering from Nismo. It is made from aluminium with a hard anodized surface finish. The Type S weights just 155gm (not that it matters anyway).

Fitting is pretty straight forward too as it can be installed in place of the OEM fuel regulator with the proper adapter.

Design wise, the the Tomei FPR comes with 3 ports on the bottom, and both sides. The bottom is for the fuel exit. One side is for fuel inlet, and the other is for pressure sensor connections. These are all 1/8 NPT sized.

I am not too sure that the stock FPR diaphragm diameter are but the TYpe S has a diameter of f33 and vacuum hose nipple diameter of f4.5. Pressure adjustability ranges from 2.0kgf/cm2 to 8.0kgf/cm2.

Oh, btw, do remember to obtain the mounting bracket (vehicle specific) as well. This is not included in the box, without it, you'll end up clueless on how to mount it on. :)
