upgrading valve springs....

[svx-t]

so...since i have the eg33 in my little impreza...with the 1v5 chip...you can actually feel the valves starting to float on the higher rpm...

so...my question is...is there just a upgrade kit just for the valve springs and retainers?

dont plan on getting cams yet...

i've read somewhere that someone is using someother stiffer springs that'll fit into the eg33...but i cant find that post no more...

so if anyone can help


thanks!
