^^ your warranty will definately be gone.
and why would you put a stage 2 kit on? you can't use the pistons or rods, which is really the only difference between the stage 2 & stage 1.
and if you're just going to do a stage 1 kit (which you should)..just get the c2 power stage 1 kit for the celica gts. (and if you really want a stage 2...you can contact them for info on the gts stage 2 kit turbo)
