Aftermarket Assassins - Original Design Water Cooled Turbo for RZR XP Turbo - OEM Upgrade Replacement

  • Turbo fits 2016-2021 RZR XP Turbo Models including Turbo S
  • We decided to offer our original water cooled turbo design with a stock PSI wastegate actuator.  This allows you to run the OEM/stock tune, or our tunes built for the OEM turbocharger.
  • If looking for more power/boost you can upgrade to the higher pressure wastegate and those tunes, but we suggest upgrading to our latest WC Turbo w/Pro XP style Housing for best performance. 
  • Requires a high flow intake tube as the OEM will not fit over our larger inlet.  The AA aluminum intake tube or other silicone intake tubes meant for the stock turbo will work.  The best option is to use the AA High Flow Intake tube with our coupler (this is an option).
  • See the differences in our turbochargers here:
  • Looking for a replacement turbo that's a major improvement over OEM? This complete bolt-on water cooled turbo is just what you need! This water cooled turbo helps keep charge temps extremely cool, making for more sustained power and cooler motor/engine/exhaust temps. Boost temps will skyrocket quickly on the factory turbo, whereas with our water cooled turbo and much larger compressor housing temps will be lower... even at boost pressures over 25 pounds! (Upgraded wastegate actuator and AA tuning required for higher boost pressures) Now that we are moving air on the intake side, we need to get that air out. This turbocharger includes a high flow 10 blade exhaust turbine with a larger bore to decrease back pressure and heat buildup in the motor. Heat buildup on the exhaust side is another HUGE issue with the OEM turbo, especially with the cheap exhaust housings which are known to crack. Our water cooled turbo utilizes a stainless steel housing that we have yet to see crack, even after hundreds of hours of hard abuse.  The factory wastegate is also a big problem as it's very weak, and as time goes on the spring only gets weaker.  Building boost with a wimpy wastegate can produce varied results, hot temps, and turbo overheating.  We install a new actuator complete with a new bracket set at the factory wastegate crack pressure.  Each turbo is fully balanced and set up from a professional turbocharger manufacturer.
  • ECU Type/O2 Color drop down choice: 2016-18 models ALL have the standard black O2 lead. In 2019+ models blue O2 leads are wideband models and we must know this if you are choosing AA tuning. These models are a different ECU type and will NOT do an ECU read (we supply your stock file). For more information on  this, see this link: 
  • Wastegate Actuator Options:
    • OEM PSI Wastegate Actuator: Can be ran on a stock ECU or AA stock turbo tunes. We set the wastegate crack pressure to the factory setting but an overboost code is still a possibility in some rare conditions and will require AA tuning.  Power levels shown below are with AA big turbo tunes. AA's regular turbo tunes will be about 10-15 RWHP less than the big turbo tunes.
    • AA 10-12 PSI Wastegate Actuator: Must use with AA big turbo tunes. See tune levels below.
  • OEM turbo inducer is 36mm, AA Turbo is 41mm with an overall larger billet wheel.
  • OEM turbo exhaust exducer 50mm, AA turbo is 54mm with a 10 blade turbine wheel for higher exhaust flow.
  • Stainless steel turbine housing has greater corrosion resistance and is less likely to crack like the OEM housing.  Stock like driveability!
  • This turbo offers Lower EGT's (Exhaust temps)  due to higher exhaust flow. Lower intake temps before and after the  intercooler. More efficient turbo all around which is easier on the turbo and motor. A must have if you ride in higher elevations where the stock turbo struggles to create boost.
  • If wanting to run the higher PSI actuator/big turbo tuens you can gain another 12-15 RWHP on  pump gas tunes over the factory turbo.   See big turbo tunes available below.
  • Our baseline results on a 2019 Turbo S were 137-138rwhp. A standard XPT has less aggressive clutching and will show 134-135rwhp stock.
    • The Level 2 turbo upgrade tune is a very safe 16-17  PSI 91 octane tune, good to run on any 91 oxy/ethanol. This tune  produces 155-160 RWHP peak(calculated 195 crank hp), but will pull much  harder and keep that horsepower maintained much better than the stock  turbo.
    • The Level 3 turbo upgrade tune offers 18-20 PSI and  is also meant to run on 91-93 octane fuel. This produces 175 RWHP  (calculated 220 crank hp) and comes on unbelievably strong, and keeps  pulling. Those with 91 non ethanol, or 93 even with ethanol will be fine  on straight gas. Those with oxygenated 91 might want to think about  adding splash of race fuel or VP Octanium/boostane fuel additive.
    • The Level 4 turbo upgrade tune is for 98-100 octane  fuel. This will produce 185-187 RWHP (calculated 240 crank hp) at 22-23  PSI and hauls the mail! Most will mix race fuel with pump fuel to get  the 100 octane which is what we recommend. A can of Octanium/boostane to  your tank will also work with this tune.
    • The Level 5 turbo upgrade tune is for 110 octane  fuel and simply drops the hammer! You'll have everyone wondering what is  done to your RZR with this bad ass tune. A huge 25-26 PSI of boost that  comes on HARD. This tune produces 200-205+ RWHP (calculated 250-260  crank horsepower) on our dyno, and has shown 215-220 on customer dynos.  We normally run this tune on 110 leaded fuel. Leaded fuel is harder on  O2 sensors but we have not had much of an issue. We would suggest  picking up another O2 sensor, or an O2 blockoff to keep around.
    • The Level 6 E-85 turbo upgrade tune is simply  unbelievable. Very similar to the 110 tune power, but runs on cheap  corn (E85) fuel! This can also be ran on VP or other E85 fuels. This fuel  makes the motor run cooler and it absolutely loves it. If using pump  E-85, make sure you are between 70-85% ethanol for this tune. 25-26 PSI  with a wicked timing curve that produces the same 200-205 RWHP. This  tune requires our 1200cc injectors and our high flow fuel pump. The  injectors are included in the price of the Level 6 tune. Selecting Level  6 will result in all tunes being built to run 1200cc injectors. You  MUST run the 1200cc injectors with all tunes if selecting this option. Supported mods needed: AA big turbo tunes for PV, AA high flow intake  tube, AA high flow charge tube, AA performance S3 clutch kit, AA blow  off valve, AA slip-on exhaust or a slip-on exhaust that has the same  flow. Power levels are shown with the AA exhaust with no quiet core  installed. Supported mods needed to run level 4-6: Tighten head bolts to  85ft-lbs or install ARP studs to 85ft-lbs, gap plugs to .020", catch  can (version 3 is highly suggested), and pre airbox intake tube 2016  models will need our 2017 style injectors and upgraded fuel pump. If  wanting to run E85 on a 2016 model, please contact us as you will then  need 1200cc injectors. How to tell if you have a 2019+ evap model :  Turbo kit includes: Complete balanced AA water cooled turbocharger with  stainless turbine housing, water lines, and instructions
