GSC Valve Guides - Exhaust - STD (FA20, FA20DIT)

GSC Power-Division valve guides are made from a proprietary blend of Manganese Bronze and turned on dedicated precision CNC turning centers. With performance and aftermarket installation in mind, we hold extremely tight tolerances on through-hole concentricity to outside diameter which minimizes the required honing time for the installer. True-to-size outside diameters minimize honing of guide bosses on cylinder heads that don't require boss service. Our guides are easier to install and shaped to improve air flow instead of just copying OEM design.

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.
