Basically, the K27 hotside (turbine housing) has the same bolt pattern, shape and size turbine inlet and outlet flanges of Garrett T3 frame turbos. While they don't appear to be 100% identical and I'm sure there are size differences in the overall length of some Garrett turbochargers vs. K27's, the mere fact that the turbine side inlet/outlet are the same means there is a huge selection of T3 frame turbos on the market that it seems have been completely overlooked by this community. For example, there are Precision Turbo "SC" series t3/t4 hybrids (still a T3 frame, though you have the option of a T4 turbine housing if necessary) to cover anything from say 200hp to as much as ~700hp in a T3 frame turbo. Ballbearing GT35r a bit expensive you say? No problem as the PTE SC61 series use a real 35r compressor and are almost identical in size on the turbine side, only difference is it is a journal bearing turbo (DBB is an option though) and they are typically just ~$700-850. Not bad for an excellent quality 600+whp capable turbo. They have such a huge lineup that they have equivalent turbos for pretty much every GT series T3 frame model. Not to mention, there are plenty of other t3/t4's from companies like Turbonetics that are affordable as well. Anyways, I just thought it was worth mentioning as with the T3 framed turbos there is a whole world of other options out there that it seems many here might not have thought about.
