| The GT2860RS is also basis for JWT sport 700BB kit although they use .86 tubine housing standard. This turbo is very similar to the HKS 2530 with just a slight difference in the compressor wheel. The GT2560R (what was and still is commonly referred to as the GT28R) is the basis for the Z1 GT600R kit. The GT2871R has a larger compressor than the GT2860RS with a 71 mm exducer. There are three different versions, all with different trims on the compressor wheels (different inducer sizes). We have a Z1 Turbo kit already produced (Z1 GT725R) that uses the GT2871 Turbos. We are installing a couple sets in the near future and should have some results shortly after. They are already available as a bolt on kit with all the same components included in our other BB kits upon request although not officially released on our website.
