Big Block Install/Conversion Kit for 1991-1994 EZGO Marathon - GX390/Clone

This is the most cost-effective engine upgrade kit available for your golf cart! Significantly increase your power and torque for only slightly more than a factory rebuild! The long term cost savings are also great for those who have a fleet of carts and are constantly replacing engines every few years. Once the cart is converted, future engine replacements & rebuilds are considerably less expensive than OEM.

4" Lift Kit Required

This is the complete conversion kit for your 1991 - 1994 EZGO Marathon (4-Cycle ONLY). This kit will not work on a 2-Cycle Cart. Specifically engineered for those who dont have the time or machinery to fabricate their own. Simply remove your old engine and bolt in your new Honda GX340, GX390 or 420cc / 440cc / 460cc Clone engine. (*NOTICE*: Our kits are designed for our VRX460 engine, using another brand of clone engine may require additional modification!)

Most of the GX390 & Clone engines are equipped with 3Amp Charging coils which are NOT sufficient in maintaining your carts battery (especially with lights or a stereo), our kit solves this problem by retaining the factory high-quality Starter/Generator so you can keep your pedal start and keep your battery charged. No Additional Wiring! No need to let your engine idle when not in motion!

Kit Includes:

  • Adjustable Engine Mount for 1991-1994 EZGO Marathon
  • Adjustable Starter/Gen Adapter Bracket, Tensioner & Belt
  • Extended Drive Belt
  • 780R Heavy Duty Clutch setup for 1-3/16" Belt
