They spool fast and have updated wheels.

The highest flowing version of the GT28 is the GT28RS (nicknamed the Disco Potato), but the most it'll flow is enough to feed around a peak of 340 flywheel horse. In comparison the SCM50, which is the smallest T3/T4 that PTE sells, will feed a peak of 450 flywheel horse. Most people would rather pay less and get the additional horsepower. The GT28RS is much more efficient and have a quicker spool up time, but won't flow enough for most DSM'ers. Hope that helps - Brian

The GT28RS is a very overrated and very overpriced turbo. Even on SR20DET's a standard Big T28 will make more power at half the cost.

"a standard Big T28 will make more power at half the cost."

I have to disagree. A Big T28 is just an old T-25 turbine with a T3 compressor stuffed in a small compressor housing. The T3's that were used for "T-28's" are rated at 33lbs max (so approx 330hp)... While the turbine was still wussy (ie: backpressure galore). Cranking up an old T-28, and your risking reversion... The larger A/R's available to the SR20 guys help ward off that backpressure... We are not so lucky (2g crowd). Otherwise you need a new GT turbine for less backpressure and better flow...

Which is where the FPBig28 comes in.
