Engines and Engine Upgrades

All of our BDX engines are modified or upgraded in our USA facility in Virginia by USA citizens.  You can pick and choose which engine performance upgrades or parts you desire and we will build these into your engine.

Anyone getting a new engine should definitely get the Uni Air Filter Kit.  Stock air filters do not filter very well.  Getting a new engine without a clean new uni filter is like taking a shower and putting on your dirty underwear.  

If you are getting a performance racing engine it is a must to get the PowerPak with it.  If you have a powerful engine you want a powerful transmission to transfer that power to your wheels the way that you want it..  The PowerPak includes the

  • Hight Stall Clutch
  • 115MM PERFORMANCE VARIATOR
  • 1500 RPM Power Spring
  • Uni Air Filter
