Product Code: SUB-STX71R-FA
Brand: SteamSpeed Turbochargers

We are pleased to announce that our FA20 ball bearing turbos are now available and shipping!  We've designed and manufactured all new components, so no core is required.  We've designed the our custom housings to support bigger compressor and turbine wheels than the OEM turbo, so expect to see a 20-30% power bump over what the stock turbo is capable of.


These FA20 turbos are stock location meaning they are a bolt on replacement for the OEM turbo.  They are designed to work with all aftermarket parts that work with the OEM turbo.  What that means is that if you are "stage 2," our turbo will bolt right up to the J-pipe, intake, intercooler, etc. you've already invested in.


The STX 71R is bassed off a genuine Garrett Japan GTX29 cartridge with our own custom 11-blade 71.4mm compressor wheel.  We have tested the 71R and validated it to make between 400-500 whp depending on fuel, and dyno.  The STX 71 is our largest option for FA20 proven to flow 59 lbs/min!  We recommend it for WRX owners who have built blocks or higher flowing motors.  


JB vs BB CHRA: The 71R features a ball bearing CHRA vs the 71 journal bearing CHRA.  Normally this means a small degree of more responsiveness; however, on the FA20 platforms, the difference is much more significant.  The FA20 produces a ton more backpressure with these larger turbos than say the EJ25.  This means that JB turbos become inefficient much more often than a BB CHRA which can stay efficient in the face of high levels of backpressure.  The other advantage is durability.  The BB CHRA will simply last longer.


We supply all of the accessories you need to complete the install right in the box, so there is no running to the dealer or part store to find gaskets and studs.
