so even 252's with 9.15mm lift would help it breathe alot more in comparison to standard.
see im doing my full 100k service so ill have the opportunity to put cams in during it, which will save me some $$$$
hence the reason why i might as well do it, as after if i dont do it n bolt turbo n supporting mods on it will cost me atleast $400 extra to install!
so it comes down to cost as well.
