Billet Camshafts

Our Products: Nissan SR20DE (T) > Billet Camshafts

Normal 4 valve per cylinder engines use 1 cam lob per valve. But the SR engine uses a single rocker to operate 2 valves. This though increases stress on the lob. Stress is further increased when up rated valve springs and higher lift cams are used. Because of this, TODA Racing has developed a camshaft with a larger overall diameter. This drastically reduces the stress, leading to improved valve timing and reliability.

Opening Valve Rate
By improving the opening valve rate via the smooth acceleration and the smoothing of the transition from closed to open the period of time that the valve is open for is greatly improved. So by using the principlies of quick but smooth actions more air can be drawn through the engine.

Non-symmetrical
The cam profile of both the opening and closing phases of the valve lift are not symmetrical, as the closing phase is designed to be long and slow, so reducing the impact of the valve when it returns to the seat. Making the valve return quietly to the seat reduces friction, improves reliability and at the same time reduces valve train noise.

Material Quality
We not only pursue improvements in power output (via mechanical design) but we also pursue material quality, in particular the relationship between the contact face of the cam, rocker arms and cam followers, so helping to reduce friction further. We also conduct research into the thermal process on the surface of the cam. All this data forms the basis for the production of many prototypes where bench tests are carried out alongside actual racing. With everything done in house there is no room for compromise and so you can only benefit from our constant search for improved performance.
