Many people have been using Tomei Powered Cams not only for the SR, but also for other Nissan engine applications for a very long time. These camshafts have long-established it as the cams for results and the variety of the camshaft profile that meets the needs and keeps satisfying end users time and time again. One example is that one of the SR common problems is when the rocker arms separate. Naturally the setup and driving style are also part of the cause of this problem but the influence by the cam lobe profile is a key factor. In such conditions when reliability is a main concern the Tomei Powered Cams can be used for engines which are also used for frequent high RPM, such as for drifting and during track use without worry. Although the same power and a torque characteristic can be obtained from various manufacturers as they develop their cams for performance the key point of security in reliability is not always available from the design from every manufacturer. When used with the stock valve springs the drop-in PONCAM can deliver impressive results with the right Valve Timing already preset and the special cam lobe profiles. More vast options are available in the PROCAM range as well. We are proud to recommend these camshafts to our clients.
