Hey fellas, my buddy has a 98' SH and he wants to dump some cash into the engine. He is debating the JS Supercharger kit vs a complete valvetrain & polished head. What are everyones opinions? Is the JR unit worth the money, or should he seriously consider a JUN valvetrain/ECU setup? Please helps us out!

Thanks!

 

The kit is good for 230 whp and a boatload of low end torque
