Surge is a concern, and I have a shop lined up to machine/port for anti-surge. The turbine housing A/R for that turbo is also a near match. The compressor to turbine ratio is inline with the original GT3071R specs: I was bothered that I wouldn't have a true real compressor map, but who does these days? Only an official Borg Warner, Garrett, or ancient MHI (never even saw one for the 152g6). The OEM Evo X turbine housing will be reused keeping the nice twin scroll design with a roomy. The result on the compressor side should be similar but not equal to the true Garrett GTX 71mm map. Due to the lower blade count: The result on the turbine side is a quick(er) spooling high(er) flowing exhaust. They made it from a decent material: 718 Inconel, but make no mistake it is NOT even close to BorgWarner gamma-ti (the best.period.), and is a slight notch down from Inconel 713c used by Garrett and MHI. The turbine is a 9 blade design they call "STS" and according to them flows 15% more than the MHI TD05 12 blade design. The compressor is "gtx style" because they have copied the 11 blade Garrett GTX71mm compressor and simply scaled it to fit a standard 20g compressor housing. Paired with a KAMAK STS 56mm 9 blade (vice 12 blade) turbine made from 718 inconel. GTX style 11 blade 52.56 MM Inducer X 68.01 MM Exducer (71.02 MM Extended Tip) What I ordered was an Evo X 20g compressor cover, TD05 center section with the following turbine/compressor: There was enough good information to be found to push me over the edge.
