FORGED ALUMINUM PISTON KIT

We supply two manufacturers of piston for FA20. There are C-series which was manufactured by Cosworth, and P-series which was manufactured by CP-CARRILLO. The R-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. The P-series realises light weight and high rigidity at low cost.

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 used SCM440. And connecting rod bolts are made by ARP. 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.

• Cannot use together with a stock piston

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 CRANK CASE BOLT

Crankshaft is one of the crucial part that have weighing by combustion power that changed rotation. Crank Case 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.

OIL PAN BAFFLE PLATE

There is some danger of cutting off of oil circulation because oil strainer could not absorb the oil, which often falls down in the situation of shortage of oil in the time of high rotation or heard driving. JUN Oil Pan Baffle Plate is a part that prevents the biased oil in a oil pan by fitting partition. The baffle for FA20 has a valve at the bottom of the partition plate, and we devise a way that oil is always stored on the strainer side. This part can be easy fit without any machining.

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.

BIG THROTTLE BODY

This big throttle body increased 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.

GT SURGE TANK

We considered the characteristics of the natural aspiration engine for making this surge tank. Then we paid attention to inertial supercharge properties of the intake manifold to make use of a quality of the natural aspiration. The inertial supercharge peaked in the normal in about 7200rpm, but we calculated a port cross section and the port head and designed it in about 8000rpm to become greatest. In addition, we attach funnels to each branch in the surge tank and note the distribution of each cylinder.

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.

REINFORCED REAR MEMBER

The sub-frame of FT86/BRZ has lack of the rear rigidity when driving at the circuit. The weak point appear conspicuously by changing coilovers. Your car will change to high response footwork with good traction by this product.
The rubber bush which was use with stock sub-frame is for the good ride quality. But, it causes distortion and lazy traction. The rigid bush will improve these weaknesses.

• Including the Reinforced Rigid Bush.

REINFORCED RIGID BUSH for REAR MEMBER

The rubber bush which was use with stock sub-frame is for the good ride quality. But, it causes distortion and lazy traction. The rigid bush will improve these weaknesses.

• You can replace the stock rubber bush easily.

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.

OIL FILLER CAP

The billet oil filler cap featuring the JUN logo adds a sporty touch to the engine bay. In addition to solid silver, it is available in four colors: gold, red, and blue, all with anodized finishes. If you would like a color not listed here, please contact us. We will provide a separate quote.

EXTERIORS

There are the original aero parts by JUN. They have the beautility and the impressive appearance. Clear coat finish were done on them.

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.
