RZR 900 XP Engine Packages for Turbo or Superchargers
How much boost? How much HP? How much money?
This kit is great for someone looking to keep their boost level relatively low. When running boost levels of 8 pounds or less lower compression is not always the best thing. When you lower the compression you will create a small amount of lag, and actually build a few less HP. By retaining the stock 10.5:1 compression ratio you will retain the snap you had with your stock pistons only with the added safety of being a forged CP piston. We provide a Cometic top-end gasket kit, mechanical cam chain tensioner to ensure the timing stays in check, a set of Billet intake manifolds to keep the seal tight and keep from having a failure occur with the stock rubber intake boots, and a set of ARP head studs. This package will allow for safe running of up to 8 psi and be a very fun and responsive setup on a recreational turbo car, or maybe even a unlimited class short course race car. If you plan to run more boost we recommend looking at a stage 2 kit or above. For more info on Stage 2,3,and 4 read the details below.
At this point the next way you are going to get a noticeable increase is to turn the boost up. Boost is where big power is made. Psi is the amount of pressure your turbo is forcing into your engine. What is keeping you from doing this is the strength of your engine's internal components. It will first break a piston. So this is what must be addressed next. By adding a set of CP forged pistons in a lower 9.0:1 compression ratio your engine becomes much more turbo friendly with a lower likelihood of detonation, and no worries of broken ring landings. The pistons alone allow you to run up to 10 psi on pump gas (some would tell you 15psi but we're playing it safe). That is a 15-20+ hp gain to the wheels. At this point you are around 115-125 Hp to the wheels. These engine package has been proven to support up to 15 psi and produce in excess of 150 rear wheel HP on race gas. This kit will include CP forged 9:1 turbo pistons, Cometic top-end gasket kit, Beehive valve spring kit, Heavy duty Shim buckets, ARP head studs, mechanical cam chain tensioner to ensure the timing stays in check, and a set of Billet intake manifolds to keep the seal tight and keep from having a failure occur with the stock rubber intake boots. There are a few options on this kit. By adding a set of our Web Turbo Cams you will gain an additional 10 hp and it is seen pretty much all across the power band. If your cylinder has damage we also offer a +3mm Big Bore Cylinder kit. This will require your stock cylinder in exchange and take your motor to a 935cc. It is available in 9.0:1 only for turbo builds. You can also add the optional 10.5:1 race pistons and build some serious front side HP and insane turbo response, but be fore-warned this setup is not for the timid and race gas is an absolute must. Available in stock bore only. Timing control/alterations are highly recommended.
This gives you as solid a foundation that can be built to push as much boost as you dare. We keep it safe and recommend staying around 15-18 psi, but know many of you will push upwards of 20psi and beyond. This kit is everything in a stage 2 with the addition or Carrillo HD rods and porting. The Carrillo rods give us the security to turn that boost up, and the porting really lets the cams flow what they were intended to. We have seen right below 200 rear wheel HP with these motor builds. We highly recommend having us install this kit. We know what these engines want and our techs build them daily.
This build is for the guys who want to go big or go home! We add a set of Stainless +1mm intake and exhaust valves to the head package and a giant +5mm Billet Big Bore cylinder setup. This not only brings the displacement up to a whopping 975cc, but also helps un-shroud those oversize +1mm valves. Properly tuned on race gas we have seen well over 200 rear wheel HP with this setup and lets just say its a MONSTER!
There's much to consider so give us a call if you have any questions. 619-562-0188.
