Stock port TII. I want to run a TO4E/S5 hybrid. Stock turbine wheel, unclipped. Compressor wheel measures 56.5 inducer, 75mm exducer.

Already have a custom v-mount intercooler and 3" exhaust. This is just an upgrade from the v-trim TO4B I was running.

How bad will the lag be?

 

57 trim to4e?
With a TO4e compressor housing also?

With a stock turbine wheel, it shouldnt hurt spool at all from what you had before with the v-trim.

 

Yeah, to4e housing as well. I guess the only thing I'll really have to battle is the clearance. A little grinding never hurt anyone
