i just got a 66mm extended tip s300 from a friend at turbo engineering. it has a 74mm clipped exhaust wheel and a .85 non gated housing. its mainly setup for a dodge but i just had the compressor housing machined to work with a ford. for a 6.0 it would need a .70 gated housing or a .76 non gated housing for street driving. this housing would be good for racing and pulling. asking 800 plus a working core. i just got my pedistal for it but i will most likely be using it when i do my twins so i would prefer not to sell the pedestal.
