Performance Camshafts & Kits

The camshaft can be likened to the "brain" of an engine's mechanical components. It controls the timing of a number of critical operations. Modified camshafts for performance have been part of the automotive scene since the beginning of the car, and choosing an after market cam can make or break the vehicle's performance and drive-ability. The cams offered by Motorsport Auto are quality pieces with cam profiles designed specifically for a Z's requirements. When you specify your usage of fuel injection or carburetion, we will give you the grind of your choice specifically tailored for your car's set up.

There are several important differences about camshaft installation in Z engines compared to other engines. Most important, a fresh valve job must be done by a competent shop at the time of cam installation. During this valve job, the machinist must be certain to keep the valve stem heights consistent; otherwise there will be severe damage to the lobes of the new cam. It is the contact pattern between the cam lobes and rocker arm pads that determines the longevity of the cam installation. We include complete, detailed instructions on these procedures with our cams. Just be advised that the attention to detail in installing a new cam in a Z engine is not to be taken lightly.

For your 70-83 L-Series Camshaft warranty to be valid, you must purchase proper new rocker arms (10-2030), Schneider Performance Spring Kit (10-2011), proper lash pads (10-2041), and Formula 2 Additive (80-9025), in addition to your performance camshaft. Used rocker arms develop a wear pattern or angle which will exert itself right into your new cam, rendering it useless and out of warranty. Stock springs can allow a valve to float at higher rpm's, and if the valve meets the piston, one or both will be damaged. Stock lash pads are about 120 thousandths. Since the base circle is smaller on a performance cam, thicker lash pads must be used. For your convenience all required parts can be purchased in our Camshaft Kit (10-2000).

For 84 & later 300ZX VG-Series Camshaft warranty, Formula 2 (80-9025) must be used for engine break-in, and while stock springs and rocker arms are used, they must be tested in good condition and within specifications. Hydraulic lifters are the most important and should be tested carefully for proper operation, and replaced if needed.

Improper installation and adjustment will also void the warranty on all camshafts. We strongly recommend not only having a qualified automotive technician do this work, we also recommend finding a technician who is experienced with Z engines, especially when setting up the 70-83 L-series engine. If you are uncertain of any of this information, or any of the valvetrain parts needed for your camshaft installation, please give us a call at (800)633-6331, and we will help you choose which camshaft is right for you, and the other parts to go with it.

Note: All cams are measured at .050" lash. Performance camshafts are intended for racetrack or other Non-highway usage. They may be illegal for use in some areas. Check the laws in your area. Don't forget gasket kits and timing kits when doing a head or complete rebuild, timing chains do wear and since you have to disassemble everything to replace the timing parts, you might as well do it at this time! Camshafts 10-2001 through 10-2006 will include a cam oiler block off plate kit, you do not need to order one separately.
