there are diferent size turbine houings within each series of turbo
for example on garetts the stock housing is a .48 all T3 turbine wheels are the same as are each series of mitsu trbo so back to the garret you put a .63 turbine housing on & you lose bottom end because more exhaust gasses are bypassing the turbine giving better exhaust flow in the top end of the RPM range its not like someone trying to put a T4 turbine housing onto a T3 there are diferent size turbine housings within a certain series of turbos the reson for this is they use a T3 on the older single turbo 300ZX a .48turbine housing would be so resrictive in that aplicaion you would get great boost up yo like 2500rpm than the exhaust back pressure would be so great that you would keep inert gasses in the combustion chamber not only heating the hell out of your exhaust valves & causing ping but not letting ny more air & fuel in
thats what those of us trying to make more HP from the 2.0 run into my .48 turbine housing is too restrictive higher in the RPMs so Ill go with a .63 & use bigger exhaust pipe to bring the lag back into a reasonable RPM range this will actualy allow me to get rid of more heat thru the exhaust & bring down EGTs
than all I need to do is figure out how to get my volvo LH to allow my engine to spinn faster than 6200rpm & Ill be stoked
enough of my rambling
