JUN AUTO RACING VALVE GUIDE FOR NISSAN VR38DETT 1008M-N009
JUN AUTO had prepared two kind of valve guide:
1. A strengthening part made of the PBB which is suitable for the tuning engine.
2. The valve guide made of cast iron which is same as stock specification.
In the case of tuned engine, the heat and mechanical load by high rotation is more extensive than stock. Stock valve guide may damage.
The JUN AUTO Racing Valve Guide improved its strength and heat dissipation by using raw material, phosphorus-bronze. This will avoid any damage from high rotation from tuned engines.
For the cast iron valve guide, JUN AUTO kept quality but cheaper than stock valve guide which is rather expensive lately.
JUN AUTO recommend these valve guides when you overhaul your cylinder head.
Material: PBB
