Just some random information for you guys.
The GT-R series are the most over rated, over priced turbos in existence.
Everyone says garrett this, ball bearing that. What the big drag guys have come to realize is, the journal bearing Borg Warner is a far better choice than the GT-R series in almost every way. The extended tip BW turbos have higher flow rates, higher surge lines, drop EGT's when compared to a comparable sized GT-R, are capable of reaching higher boost levels, is rebuildable and cheaper. The BW turbo at the same PSI will make more HP than the GT-R Garrett.
The GT-R series will spool 100-250 rpms faster than the BW turbo.. Thats all garretts got. BB turbos are kind of a gimmick if you ask me, and have been pushed on the turbo crowd for a long time by Garrett. They want you to not be able to rebuild the turbo, it makes them money.
Currently, pretty much all the drag guys have figured out that the BW is the way to go. The GT42R is NOT the main drag turbo anymore, its been replaced by the S372.
