Re: What Turbo?
PT67 P-trim with "S" cover : new style compressor, old style turbine. also the smallest turbine and the fastest spoolup. 4" inlet 2.5" outlet. i believe there is now a p-trim in the GT series of turbines..... but id have to double check that. i havnt seen it first hand yet. this turbo is also available in dual ballbearing or standard.
PT67GTQ with "S" cover : new style compressor, new style turbine. midrange turbine for good all around peek HP and spool. GT turbine = more expensive. 4" inlet, 2.5" outlet.
PT67GTQ with "H" cover : same as above but with a 4" inlet and a 3" outlet.
theres also a race cover with a big bellmouth, but its meant to be run without a filter so i wont even get into that.
PT67GTS with "H" cover : new style compressor, new style turbine, large turbine, all things equal this will boost top end and negatively affect spoolup. good race setup.
hope that helps..... getting tired of typing. lol
