(These bearings below will also fits 18R, 18RC, 18RU and 16R engines)




What is WPC?
WPC is a proven process that has been utilized for many years in the racing and automotive industry.
WPC is not a coating, it is a treatment that enhances the surface to reduce friction and strengthen engine parts.
WPC achieves this process by firing ultra fine particles towards the surface of a product at very high speeds.
The resulting thermal discharge permanently changes the surface, strengthening structure and creating a harder more durable final product.
The WPC process is unrivaled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by any current conventional methods of surface treatment.

18RG Bronze Valve Guide Kit

Price $184.27 usd



The demands of valve guides are resistance to wear and abrasion, tolerance to high temperature, and seizure. 
This is only accomplished by combining two metals and precision machining of the inside of the guide.  In addition these guides only allow the
minimum valve clearance so that the valves are moving properly during high RPMs. With this type, it is possible to decrease the valve clearance
by a small amount because  of its efficiency at dissipating heat and resistance to sticking valves.

Specification:
Size: Intake 51mm / Exhaust 51mm
Material: Phosphorus Bronze

18RG Aluminum Lightweight Flywheel  9.5 lb. (4.4 kg.)

Price $371.67 usd


You will defiantly feel a gain in power with this modification.

15+ Horsepower!

- Frees up horsepower available for acceleration
- Quicker shifts
- Allows easier heel-toe shifting
- Extends transmission synchro life
- Extends engine main bearing life
- Reduces overall vehicle weight

Features:

- Has a replacable clutch friction surface so you never have to cut or resurfaced the flywheel
- SFI approved
- Awesome 6061 Aluminum construction
- CNC machined
- Heat-treated special alloy steel friction surface for excellent durability and inexpensive replacement
- Brand new starter ring gear

Aluminum flywheels are made from the highest quality 6061 T6 aluminum. The material is fantastic for strength, heat dissipation and of course reduction in weight. The friction surface we use is an incredibly strong 1050 steel. The plates are milled to meet our high specifications. This flywheel can mate with any type of clutch material, including organic, Kevlar, ceramic, metallic and sintered iron. We attach the friction surface with military grade aerospace fasteners. The ring gears we use are also made from 1050 steel and are heat treated for durability. The gears are heated then pressed on and secured with grade 8 button screws. We were the first to utilize a stepped dowel system in our flywheel. This doweling method ensures that once the pressure plate is installed the dowels cannot be removed because they become locked into place. Flywheels are designed and builds with extreme precision. We give tuners, racers and builders the high performance and unmatched power they’re seeking.

18RG Performance Thermostat

Price $65.78 usd


Born from racing technology!
71 Degrees Celsius Low Temp Stainless Thermostat

What is the optimum temperature to get the most power from the engine? 

Different parts of the engine are at various coolant temperatures. For example, the temp gauge is reading at 80 degrees Celsius but at the back of the motor, it is between 85 and 90 degrees Celsius, which means it is detonating.  The perfect temperature for optimum performance is the temperature right before detonation, measured at the cylinder.  However, in order to achieve this temperature, it is absolutely necessary to have good cooling efficiency and a low temperature thermostat. The thermostat opens the valve at 71 degrees Celsius and allows the coolant to flow earlier to prevent overheating and bring out the maximum performance from the motor.



PERFORMANCE RADIATOR CAP

Price $45.00 usd

 


This radiator cap has an upgraded 1.2kg/cm (12 lbs.) pressure valve spring, so that the maximum cooling potential is achieved from the radiator. For example, even though the coolant temperature is climbing over 100 degrees Celsius and the internal pressure of the radiator is high, the coolant will not boil over.


This radiator cap is good protection against overheating because stock will only hold up to 0.9kg/cm ( 8 lbs ) of pressure and the coolant will boil over at 125 degree Celsius
