a b16 will never spool a t4 60-1, and it won't be fun on an sc61. just some FYI, im going to run the sc61 with the to4s wheel.... on my 2L motor.
on a 1.6, you are going to dog.
there's basically 2 types of turbos out there...
The E family has 6 compressor blades and 12 total including the sub-blades.
The B family that has 7 blades and 14 total including sub-blades.
that's the main difference between to4e and to4b.
im not sure off hand what the to4s is complied of.. i gotta figure that out...
there's just 1000's of different wheels, trims, housings, inducers, exducers, and so on.... its really hard to "pick my turbo" without having a realistic TOTAL power goal.... one you can afford.
