FORGED ALUMINUM PISTON KIT
We got the cooperation of the Wössner GmbH in Germany, and expanded the line-up of the piston. This W series is an excellent product in the cost performance. It is an excellent piston in the durability because it is the design which has a few loads that heat efficiency was put on the emphasis. We made many types of vehicle and bore size. A choice in your needs will be able to be done.
HIGH LIFT CAMSHAFT
This camshaft was ground from forged material which was designed for 4B11 engine. The form (profile) will become the best logically because cam design has flexibility by grinding from material.
Regular Camshaft Series
64(256)-10.0 / 66(264)-10.8
68(272)-11.0 / 70(280)-11.0
MSRP: JPY39,900yen
CAMSHAFT KIT
You can choose the camshaft kit by your driving stage. The camshaft kit includes reinforced valve spring which is necessary part for high street spec any more. The camshaft can choose from the regular camshaft series.
STAGE 1: JPY102,900yen
Camshaft 1 set + Reinforced valve spring
STAGE 2: JPY147,000yen
Stage 1 + Ti valve retainer (Type1)
STAGE 2R: JPY160,650yen
Stage 1 + Ti valve retainer (Type2)
REINFORCED VALVE SPRING
The JUN reinforced 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.
MSRP: JPY25,200yen
TITANIUM VALVE RETAINER
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.
REINFORCED VALVE GUIDE
The JUN Racing Valve Guide is improved its strength and heat conduction by using raw material, phosphorus-bronze. This therefore avoid the any damage from high rotation of tuned engine. We recommend our valve guides when you overhaul your cylinder head.
Phosphor bronze JPY26,880yen
BAFFLED OIL PAN
In the race scene to repeat rapidly acceleration, slowdown, and turn, a strainer cannot suck in oil with the stock oil pan without partitions because lubricating oil has always clustered on one side of the oil pan. This baffled oil pan always can keep a strainer into the oil surface because it prevents to lean the oil by making a partition in an oil pan.
MSRP: JPY44,100yen

FORGED CHROMOLY FLYWHEEL
JUN could achieve manufacturing its original flywheels about 200% more strength compared with normal flywheels. It was forged using Chrome-molybdenum steel. The power of inertia rotation can be decreased by reducing the excess weight, and therefore, its strength directly passed through to the high response.
Ultra lightweight: JPY46,200yen

SINGLE SPORT CLUTCH KIT
The JUN clutch kits can strengthen your drive train all at once because all of our clutch kit contains clutch disc, clutch cover, and lightweight flywheel. Our new lineups which are the clutch disc and the clutch cover have strength enough for the race scene.
Sport disc w/ Ultra lightweight flywheel: JPY107,100yen
S-Metal disc w/ Ultra lightweight flywheel: JPY115,500yen
MODIFIED INTAKE MANIFOLD
This intake manifold can install the high flow fuel injectors which is necessary to build the high power engine. And, this product contains necessary parts to install third-party injectors. The injectors which is available for this product are 650cc, 800cc, and 1000cc manufactured by SARD. A fuel delivery pipe can use a stock product as it is.
* The prices are not contained manifold body. You need to send your intake manifold to us.
MSRP: JPY33,600yen
BIG THROTTLE BODY
This big throttle body increased 20% of the air flow more than a stock part by expansion of throttle diameter. Basically, you need to send your throttle body to us because we modify your throttle body. We can prepare a brand-new throttle body as the other choices.
* The prices are not contained throttle body. You need to send your throttole body to us.
MSRP: JPY36,750yen
UPRATED TURBO ACTUATOR
This is an uprated turbo actuator which can adjust working pressure from 1.0 to 1.3 kgf/cm2. This turbo actuator will prevent declining of boost pressure when high rev and boost. You can install by bolt-on because the actuator is designed by same form as a factory one.
MSRP: JPY34,650yen
ALUMINUM BLOW OFF PIPE
This blow off pipe kit will improve the pressure loss and come off pipes by exchanging to aluminium pipes and silicone hoses from stock rubber hoses. The atmosphere of the engine room is favored by buffing aluminium pipes and silicone hoses.
MSRP: JPY29,400yen
STAINLESS EXHAUST MANIFOLD
This is an Exhaust Manifold compatible with factory one made by stainless. We devised pipe shape and a diameter not to disturb a flow of exhaust emission and reviewed balance between exhaust flow quantity and exhaust pressure. As a result, start of a turbo in the whole rev became smooth.
MSRP: JPY144,900yen
TURBOCHARGER SETUP KIT
The Turbocharger Setup Kit will soup up your Lancer Evolution X very much. This kit realizes an incomparable performance with the stock turbocharger because the TD06SH-25G which has the latent ability of 500 whp can use. JUN Evo X which was our demonstration car showed really 630 whp with our Custom Kit EX2.3L.
* The turbocharger, the wastegate, air cleaner, and air-flow adapter are not contained. Prepare them separately referring to the above.
MSRP: JPY472,500yen
UPRATED OIL THERMOSTAT
This oil thermostat prevents to decrease oil flow through oil cooler by insufficient shutting up of the valve.
MSRP: JPY12,600yen
ALUMINUM RADIATOR PIPE KIT
This radiator pipe kits will improve durability by exchanging to aluminium pipes and silicone hoses from stock rubber hoses. And, the upper pipe kit has advantage for racing scene which required severe control of temperature because it has a boss of water temperature sensor.
RADIATOR CAP
This radiator cap uprates the pressure of release valve. That result, boiling point of coolant is raised by increases pressure of piping. By this, it raises the cooling efficiency of the radiator, and will repress overheat.
SPORT COMPUTER
This computer is a boost-up ECU. You will be able to get a big performance by the boost-up, an optimized fuel and ignition map, and removing speed limit.
Modification: Boost-up, Optimized Fuel and Ignition Map
* This computer will fit your car which exchanged parts until exhaust muffler, catalyst, and air cleaner.
* This product needs your stock computer. You need to send your computer to us when you buy.
MSRP: JPY155,400yen
SIDE SILLS FOAMING URETHANE KIT
This new reinforcement method makes high rigidity feel simply, so that it reverses old common sense. The car which performed urethane body reinforcement can feel the difference, when it get in and departs, you feel a motion of a car. The car which has constructed the roll cage etc. is still more effective. Although there is a difference in the ratio of an effect also by the new car or the old vehicle, rigidity is raised certainly.
MSRP: JPY31,500yen
UNIVERSAL REAR SEAT BOARD
After a rear seat is removed, this product is used as a bulkhead. The Universal Rear Seat Board will make a stylish cockpit without weight because it was made by the carbon. Cut these boards along the form of your car, and use.
* Shape it to the form of your car
