PRODUCT NOTES:
- The amount of lifts shows the cam lift.
- You can choose from the Camshaft profile previously listed.
- The amout of lifts shows the cam lift.
- When you use it for S14 or S15, you must change a cam sprockets into S13 type. In this case, the variable valve timing mechanism (VVL) does not work.
- You cannot use the lash (LHA) type camshafts on the Pulsar (RNN14). You must choose the solid (shim) type camshafts.

FEATURES:
Camshafts:
Discerning in Perfect Development Environment:
The cam profile which influences the performance of a Camshaft is the most important element in a Camshaft design. At JUN, the software only for cam profile designs is used, and the automatic design by the computer is performed. In order to test the cam shaft designed on the desk, the engine bench system of JUN which has combustion pressure measurement equipment is used. This system can analyze the state in a combustion room for every crankshaft angles. Various profiles can be tested.
The Profile Optimized According to the Type of Car:
Even if it says a Camshaft in a word, the profile form is various by the type of a car. Profile form is decided in consideration of the difference of valve motion method etc. (direct type, a locker arm type, strength of moving part, valve size, port and combustion room form). If depending on types of a car, a profile may be restricted by the wall in a head, lifter hole size, locker arm form, etc. At JUN, when developing a high Camshaft, the detailed data for each type of a car is taken, development is furthered simultaneously with a valve spring and retainer, and the optimal profile is determined.
The Main Point in a Development and a Design:
You have to raise 'filling efficiency', in order to obtain a high output. Being required of a cam is lengthening time which the valve's is opening. It is necessary to increase the amount of cam lifts in order to lengthen time which the valve is opening. The negative acceleration will become large if the amount of lifts is increased simply. The 'jumping phenomenon' in which a valve separates from a cam, and the 'bounce phenomenon' which is bounded when a valve contacts a valve sheet ring occur because when negative acceleration becomes large, the acceleration of a valve will exceed the acceleration of a cam. These phenomena not only spoil the performance of engine original but cause breakage of engine. The high Camshaft must realize the conflicting element with which 'extension of time which is opening the valve', and 'reduction of negative acceleration'.
JUN high Camshaft took positive acceleration large, and the action time of negative acceleration is keep a long time by shortening positive action time. By doing so, when a valve moves from opening operation to closing operation, a valve can move as smooth operation and can prevent jumping. Since positive acceleration becomes large at the side of close, the valve just before closing is added the strong brakes by the cam. The bounce phenomenon is prevented. The time near the maximum lift can be kept for a long time by opening a valve in a short time. Therefore, the good valve motion of efficiency is possible. The simulation and an experiment of the valve motion system are conducted based on such design theories, and a profile is determined. Here is the true performance for which a high lift Camshaft is asked.
Valve Springs:
When valve speed increases by high rotation of engine, 'Jumping' may occur by the factory valve springs. Moreover, since inherent pitch is low, 'Surging' may occur in a high rotation region. In JUN, the valve spring with which the load optimal at the time of a set and a valve lift is acquired was manufactured. Even when the amount of valve lifts increases by using a high cam, since the adhesion margin is secured enough, the JUN valve springs does not have degradation and its durability is also improving.
Retainers:
In order to obtain a high output, it is necessary to turn engine by high rotation. However, when using engine in a high rotation region, valve jumping becomes easy to happen and the danger of engine breakage increases. Therefore, it is required for tuned engine to make a movement part light. The role of a retainer is a stopper for valve springs, retainer needs to be extremely strong and lightweight for reliability and engine response. The JUN Titanium Valve Retainer has been developed with emphasis on both strength and weight in mind.Furthermore, the Type2 valve retainer is performing the special surface treatment. And compared with Type1 (conventional article), wear resistance of it improved very much.

Have been using these plugs for long time. Truly worth the investment for race use.

The parts were of excellent quality and the fitment was perfect!

Nice finishing on the emblem, put at my FK8. recommended to buy.
