GSC Valve Guides (EJ20, EJ25)

What GSC Power Division have done is actually quite simple: they made valve guides that fit properly, easier to install, and shaped to help air flow instead of just copying the OEM design. 

GSC Valve Guides (EJ20, EJ25)


GSC Power-Division was started to fill the need for high-quality performance camshafts and valve train components for the Japanese sport compact cars of today. With little worthwhile offerings in the market, and a passion for quality and performance, GSC offers cutting-edge designed camshafts and valve train components that are lighter and handle the most extreme conditions of the turbo sport compact engine.

The GSC Power-Division valve guides are made from true C67410 Manganese Bronze and turned on a dedicated precision CNC turning center. What this means for you and your installer is less time fitting guides to the head due to holding the tightest tolerances in the industry with the best quality control possible.
