XP4-900 Z1 Hybrid Swap

Well, I’m jumping ship on the Polaris 900 motor as well. After many issues with turbo charging and finally loosing the Aerocharger turbo itself I’m tired of fixing it and having an unreliable machine. I WAS running E85 and 13+psi. I really didn’t have actual engine issues, all of it was related to the exhaust system and turbo itself. But of course am now highly addicted to boost and HP!

I’m calling this a "Hybrid Swap" because plans are to obviously use my XP4 900 chassis (I just have too much $$$ invested and its setup with all the creature comforts I want for both trail & dune riding), but install more like an XP1000 leaving the turbo in the factory Arctic Cat front location. Jason Hawk has been kind enough to let me "piece meal" his kit / parts a few at a time as my build progresses since several aspects are undetermined.

My XP4 is a 2012 with MANY extras – I won’t bore you with a list. I already have a water / air intercooler & pump installed so may or may not use it from the Aerocharger kit. Still have all my turbo related gauges, boost controller, etc. I have been running N/A for the last few months. Although low HP compared to boost is in good condition and will be for sale soon to run as is or its ready for boost. As well as all other associated parts not needed.

KNOWNS ———-
Yes my car is a 4 seater! I did need 4 seats when I bought it, but in the last year we have gone on several trips where no one sat in the back. So with the "Hybrid" part I know I’m going to loose at least the rear passenger seat as the turbo & exhaust will surely be in the way. I hope to retain one rear seat on the drivers side, but if I can’t that is ok too. Probably gonna have to move the upper shock mounts outward slightly to clear exhaust.

I already have an oil cooler and fan installed and will retain it mounted in a fashion to also help move air in and around the turbo.

I already blew a transmission bearing at 1450 miles, so those are all upgraded and should be good. Also running some of the larger Chinese axles & CV’s – Good so far!

UNKNOWNS ———-
Air / Air or Water / Air
Fuel Tank – size, location, etc.
Reflashed Stock ECM or Vipec
Stock Primary Clutch or Rage 8
Charging System – I hope stock is enough?

Shortly after loosing the Aerocharger a few months ago I found a 2014 Z1 with 85 miles. Complete with harness, dash, clutch, turbo, sensors, etc. COMPLETE!!

Just waiting of first shipment of parts from Hawk!
