  • Ready to step up to the next level on your XPT and gain some serious power? Up to 255-260 crank horsepower! This complete turbo modification is just what you need for 25-27 PSI of boost!  This is NOT just a simple billet wheel turbo mod, we are doing it all!  We start off by modifying the compressor housing to accept the much larger, billet compressor wheel that will move some serious air.  This gains turbo efficiency to push more air per RPM of the turbo.  Boost temps will skyrocket quickly on the factory turbo, where as with our mod, they will be much lower... even at boost temps over 25 pounds!  Now that we are moving air on the intake side, we need to get that air out.  Our mod includes a high flow 9 blade exhaust turbine to create less back pressure and heat buildup in the motor.  Heat buildup on the exhaust side is another HUGE issue with the factory turbo.  What's essentially happening is you are running out of exhaust flow, and that makes more power very hard to produce.  With this high flow turbine, we can increase boost and see a healthy increase in horsepower with our tuning on pump gas and race fuel.  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 high pressure actuator complete with a new bracket.  This wastegate has extremely consistent results, will hold a huge amount of boost, and is a key component in this turbo mod working so well.  Each turbo is fully blueprinted and balanced with new bearings from a professional turbocharger manufacturer. 
  • Thinking of another turbo mod?  Many of our competitors offer an inferior mod, and do not offer the advanced tuning we do. Many use stock wastegates, do not bore the compressor housing, or do not modify the exhaust turbine.  These are all huge reasons why our turbo mod works well. Tuning changes are drastic for modifications like this, and many others do not have the correct tuning knowledge to pair with such mod.  
  • Turbo modification for 2016-Up RZR XP Turbo Models including Turbo S
  • Requires AA custom tunes built specifically for this turbo mod
  • ARP head studs are required
  • Requires your turbo to be sent in for exchange or modification.  We have some exchange turbo's to speed up the process as all turbos are basically remanufactured to brand new.  If you have a stripped bolt hole or other turbo damage, please let us know ahead of time.  If this is the case, we will need to fix the issue and will most likely have the mod done to your exact turbo, and send that turbo back to you.  Turbo mod turnaround time can vary from 0-3 weeks depending on core availability. Normally cores are kept in stock.  If you would like the modification done to your own turbo, lead time are closer to the 3 week timeframe.  Please call or e-mail for current availability if you are in a time crunch. Core charge available for $600 which will be refunded when a good usable core is sent back.

  • Stock like drivability!
  • On our dyno we saw 204 RWHP @ 27 PSI on 110 octane with some serious top end pull.  Other customers on car wheel dyno's have reported 215-220 RWHP.  That's a calculated 255-260 crank horsepower! 
  • Gain another 10-15 RWHP on pump gas tunes over the factory turbo (19-20 PSI on 2017+ models, 18-19 PSI on 2016 models)
  • Big gains in low end performance and crazy high end gains on longer pulls (this mod does not fade off anywhere near as much as the factory setup)
  • Lower EGT's (Exhaust temps) due to higher exhaust flow
  • Lower intake temps before and after the intercooler
  • Using the factory turbo, we are able to keep reliability, proper heat shielding, and proper mounting points.  The factory turbo was designed for the off road world of dirt, water.  This made it hard to shy away from something so proven, but just needing a little more flow.  Others may bore the exhaust side out, buyers beware!  This is a fragile part of the turbo and we have seen various cores with a crack between the exhaust turbine and wastegate.  Boring this would simply mean it would be much more likely to crack.  Our goal is to give you the most horsepower possible while still having a reliable machine.
  • The Level 1 turbo upgrade tune is 14-15 PSI like a stock 2017+ model and is for those needing a near stock tune for the turbo mod
  • 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 150-155 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 165-170 RWHP (calculated 215 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 or ethanol 91 might want to think about a little bit of race fuel or VP Octanium/boostane fuel additive.  
  • The Level 4 turbo upgrade tune is for 98-100 octane fuel. This will produce 180-185 RWHP (calculated 235 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 25-27 PSI of boost that comes on HARD.  This tune produces 200-205+ RWHP (calculated 260 crank horsepower) on our dyno, and has shown 215-220 on customers car 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 fuel, or expensive VP corn fuel!  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.  25-27 PSI with a wicked timing curve that produces the same 200-205 RWHP.   This tune requires our 1200cc injectors.  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 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.
    • 2016 models will need an upgraded fuel pump to run Level 3 or higher

    • If you need to purchase a Powervision, purchase the tuner with the turbo upgrade tunes HERE
    •  Mod includes:  Machined compressor housing, billet compressor wheel, high flow exhaust turbine, high pressure wastegate actuator, new bearings, head to turbo gasket, fully blueprinted & balanced turbo. Turbo looks new and is basically brand new when returned.  We re-use the turbo to exhaust gasket as it's metal.
