i've been looking into the full-race turbo kit and found that the kit comes in four stages, but i couldn't find a list of the differences between the stages..... anyone know?

 

Stage one - comes with t3/t4oe 57 or 60 trim turbo, 38mm tial wastegate, 8x20x3 IC

Stage two - comes with the 60-1 t3/t4, 40mm tial wastegate, 8x20x3 IC

Stage three - comes with the t3/t67, 40mm tial wastegate, 8x20x3 IC

Stage four - comes with the t4/t67, 46mm tial wastegate, 11x20x3" IC

You can special order the kits with the GT series turbos for extra, as well as get the anodizing option for the intercooler and intercooler piping. These are extras to the standard kit prices.
