FORGED ALUMINUM PISTON KIT

There are two types of pistons for the VQ35DE: the C-series manufactured by Cosworth (U.K.) and the P-series manufactured by CP-CARRILLO (U.S.).

I-BEAM CONNECTING ROD

The JUN connecting rod is made by shaving in order to pursue lightness and strength, this form has no futility. The material of a connecting rod is SCM440. If big end is transformed at the time of high rotation, a metal will burn. In order to prevent the phenomenon, it was made the form which distributes stress.
The 6mm stroker rod is special product which can use with 3.8L crank shaft. You can increase displacement volume as an NA engine by using the high compression piston with this product.

BILLET CRANK SHAFT

The JUN crankshaft made from shaving has flexibility in a design as compared with a forge product. A high rigidity and balance rate help acceleration with no stumble, accordingly it is able to build a high response engine.
This crank shaft extends 6mm. You can increase displacement volume by using the special rod for this product.

HIGH LIFT CAMSHAFT

This camshaft was ground from forged material. The form (profile) will become the best logically because cam design has flexibility by grinding from material.

• The camshaft which is 11.0mm or higher lift of the profile needs to use uprated valve springs. You need to prepare application valve spring separately.

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.

REINFORCED HEAD BOLT

The high-boost and high-compression engine tends to occur distortion between the cylinder head and the cylinder block as a junction part of combustion chamber. We are providing the product which is supplied from ARP Racing USA.

REINFORCED CRANK MAIN CAP BOLT

Crankshaft is one of the crucial part that have weighing by combustion power that changed rotation. Crank Main Cap Stud Bolt is a shaft bearing part of crank shaft that fixes a block and a cap connecting together. If this part gets thermal expansion a crank housing could not be kept in circular shape and it could be possible to get scorching. We are providing the product which is supplied from ARP Racing USA.

REINFORCEMENT CONNECTING ROD BOLT

Unquestionably the most important fasteners in any engine are the connecting rod bolts, as they hold the key to the entire rotating assembly.

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.

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.

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.

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.

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

UNIVERSAL FRONT DIFFUSER

An air pocket in central part amplifies incoming air from bottom of front bumper temporarily and the compressed air quickens speed, and it is drained behind your vehicle. Strakes before front wheels reduce turbulence by the tires, and the air deflects to center of vehicle. The quickened air makes down force occur through bottom of vehicle. Moreover by the type of vehicle, this diffuser has effect which lowers water and intake temperature because it pulls out heat from engine room.
