It depends on your horsepower goals. A true 60-1 is a full T4 turbo, on the 2.4, that wont spool til about 5,000 which will leave you with a 2500RPM powerband. Also, the power is gonna go instant from no power to full power when that thing hits. An SC61 is pretty much a non-ball bearing GT35R but with a 3" inlet instead of 4" inlet, this is the turbo I have, on a 2.0 it spooled at about 4200, on a 2.4 prolly about 3800 give or take. That was with the .63 A/R turbine housing and Stage 5 turbine wheel. Pretty much that setup is the largest non ball bearing T3/4 turbo. They dont call it a 57-1, its just called a 57 trim. Very similar to an SC61 except with a smaller compressor wheel. This turbo will spool up a little quicker, especially if you get it with a ball bearing cartridge. The 16g is really small for a 2.4 motor, I think you will end up with it topping out in the high 6,000 RPM range and the power will level off instead of climbing.
Power wise.....
60-1 (depending on which one you get) anywhere from 400-650whp
SC61 is good for about 550-600whp with a good tune
57 trim is good for about 475-500whp
Big 16g, im not too sure, prolly around 400whp.
