Yeah it was my first intention going into the build. But I am not seeing real great results when compared to the HTA35R
It does make more peak power , but not huge , and it is far more laggy than the 35 . The HTA35R power curve is just so much larger the the 37. In alot of areas of the graphs I have seen the 35 is up on the 37 by large numbers on most rpm areas of the graphs , until the very end peak power the 37 pulls past the 35 but usually not till the very end of the pull.
Its a toss up. seriously the average power across the board on each turbo are real close. Just the 37 peaks a bit higher.
