But to answer your questions, yes you can fit the .48 housing now the turbine wheel is not changed when you go stage 3 (or ever in fact) and to fit the 55 trim comp wheel the housing needs to be machined out.
cheers matey will give him a shout when the time is right. just trying to decide on which route to take. will most likely jump in with dekas (for 250bhp might be worth a gamble from states.) and a stage 3 early next year. for now the priority is getting housing changed and the lump mapped and run in with cossy blues. will the .48 make any gains over the .48 with a standar core. presume it will flow better? ony going to 15ish psi with blues. or would a .36 be better off?
