RZR Pro XP/Turbo R/Pro S Big Turbo (And OEM Replacement) - Up to 330HP

The Aftermarket Assassins Big Turbo is a complete replacement turbocharger for the 2020 and newer Polaris RZR Pro XP, Turbo R and Pro S, built as a tougher OEM replacement or the base for up to 320 to 330 crank HP.

Why it holds up

• Larger compressor wheel and housing with a 44 mm inducer, versus the OEM 40 mm, to push more air per turbo RPM
• High flow 10 blade 44 mm exhaust turbine, versus the OEM 41 mm 11 blade, for lower EGT and less heat buildup
• High pressure billet wastegate actuator with a new stainless steel bracket replaces the weak factory wastegate
• Fully blueprinted and balanced with new bearings by a professional turbocharger manufacturer
• On the AA dyno it made 261 RWHP at 28 to 29 PSI on 110 octane and 267 RWHP on E85

Fits

• 2020 and newer Polaris RZR Pro XP
• 2022 and newer Polaris RZR Turbo R and Pro S

In the box

• Complete turbocharger with exhaust housing and manifold
• Billet wastegate actuator with stainless steel bracket

Good to know

• Standard Turbo: cast steel exhaust housing and manifold from an improved casting process, with an 11 blade compressor wheel most efficient at 15 to 25 PSI. A good fit for replacing the OEM turbo and running OEM programming.
• Premium Turbo: stainless exhaust housing that resists the cracking around the exhaust port common on OEM housings, an upgraded v band clamp and a lighter 6+6 compressor wheel less prone to surge.
• Runs on stock tuning or AA Level 2 all day. AA tuning is required for higher boost pressures.
• Levels 4 to 6 require all AA bolt on mods, a catch can and head bolts torqued to 85 ft lbs or AGE 625+ head studs. Levels 5 and 6 require AA 1200cc injectors, and running over 25 PSI requires a billet crank.
• Race tunes are mostly for drag racing and are run at your own risk for extended periods.
