Go Fast Bits (GFB) part gfb5933. Because T9133 is the 33mm Mach 2 used on Mitsubishi Evo platforms, this is the conversion kit most Evo owners need when moving from plumb-back to atmospheric venting.
Fit the firmer spring only if the piston hovers open at idle with preload maxed, otherwise the softer original is fine. Other kits are gfb5920, gfb5925 and gfb5930.
