Hi all , am interested in grafting a smaller 50 or 52 trim compressor into a Garrett GT35R . The reasons are that many are caught between using the GT30R and GT35R because the void between them is a bit wide . A smaller trim comp would allow the "GT35RS" to come on a little sooner and have a little more turbine efficiency than the GT35R has .
HKS's GT3040 uses a GT40 50T comp so if found could be drilled to suit and could bolt up with its .60 ar housing . Alternatively Garrett do use GT40 50 and 52 trim compressors in their bush bearing GT4082 and GT3782 turbo but the wheels need more mods to fit (backspacing) . I guess if all else failed an example wheel could be traced on a CNC lathe and the smaller profile machined onto the larger 56 T wheel . Then it will bolt up . The nicest option would be for Garrett to make them for us as their is no HKS turbo that is the same spec - their GT3240 uses a 54 trim GT40 wheel and the GT35 turbine is cropped to approx GT32 turbine dimensions .

Opinions ? Cheers A .
