Some riders looking to increase performance have reached out to us asking about engine builds and aftermarket engines for the RZR 4. When you start to delve into engine replacements, though, you better have a lot of skill or a lot of money -- and realistically you're probably going to need both. We've seen RCV, Rs1, ORB, FCR, KB3, PRP, TQR, and Keller engines being used in the RZR 4. We've also seen 1000 and 1100cc gsxr engines, Busa engines, and even a 1100 turbo snowmobile motor work in an RZR. Some are made for higher top speeds, while others provide faster takeoffs. But unless you're a racer, most riders will find that the stock RZR 4 engine is sufficient for most types of riding. If you're curious about what type of engine you can put in your RZR 4 or want to learn more about / buy engine parts, components, or rebuild kits, give us a holler and we'll sort you out.
