Subaru WRX/STi's have been known to the performance world to make big power for years now. 600, 700, 800 hp and more have been attained and made some ridiculous ET's at the drag strip. Up until now though, those results have been achieved with a non stock location, rotated turbo. To change all that, we are excited to introduce the Xona Rotor Ball Bearing Zero 86 HTZ for Subaru. This ball bearing turbo uses our 86 HTZ wheel and 84MM Flow Advancement Port compressor cover to flow a massive 78 LB per minute which would send a well sorted motor into the 700+ horsepower range.
These numbers are impressive, but they are really only half the story behind why this turbo is revolutionary. The real kicker here is the increased turbine flow thanks to our new 10 cm stock location Subaru turbine housing. That means you can make 700 horsepower on a non-rotated, stock fitment, simple to install turbo! To do all this without needing a custom exhaust manifold, up-pipe or down-pipe, to not run into the ABS components, to not need to piece together a rotated turbo kit, is nearly unheard of! Testing has found no significant clearance issues on most cars, making this the easiest to install big number Subaru turbo we have ever seen. Additionally, due to the nature and size of this turbo, we are not recommending it be optioned with an internal wastegate so an external gate will be recommended to run this turbo.
