The turbo is custom built to my spec 30-71 Garrett with external waste gate and Tial SS V band Exhaust housing. Air box is o ringed and slides over T-body.* Charge tube has 2 injectors spaced apart called I.C.System {Injection Cooling} Please call* Ken @ 651-303-3867.
You can run a smaller exhaust housing as you are wasting the exhaust before the turbo rather than all of it running threw it, smaller housing faster spool up, less lag, more efficient. Possibly have lower drive pressures as well.
