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.

Yes, I understand that the GTX is better, but they're using that for the upper stage TT kits, I was more questioning the 'stage 1' kit, since that's what I will most likely be getting in the future. Thank you for your response though, learn something new every day

I suppose, but it's a small difference (~$100 or so) between the two. I guess the GT28RS would be better for DD purposes compared to the 2871 anyway.
