Is it possible to use those instead?

They are using a much more superior turbo than the normal 2871R. The 2871R is actually not a "great" turbo. The compressor wheel to turbine wheel size difference on the 2871R introduces a very inefficient weak spot on that turbo that will make it laggier and not as responsive. It has too much back pressure as well which is death to any turbocharged motor. If your going to use a 71 wheel you want to step up to a 3071 that uses a larger turbine wheel.
The FI kit uses a much much much better turbo using the new Garrett GTX compressor wheel.
