Looking to put your Datsun Z Car cooling system woes to bed for good? We’ve got a new product that was developed on one of our development vehicles and torture tested in the Texas Hill Country during Texas Z Fest. We have also torture tested this kit in the raw heat of Texas during stop and go 5 o’clock traffic, and it has far exceeded our expectations.

With an integrated aluminum fan shroud, this cooling fan kit moves a combined 4200 CFM of air across the radiator, and the brushless fans mean less load on your electrical system and more longevity. You will not find a better, or higher flowing cooling fan kit on the market to date!

This kit was built out of necessity on one of our high performance vehicles. The big turbo, combined with a very hefty high overlap cam contributed to a ton of heat, and we finally were able to exceed the capacity of our best selling Dual SPAL Fan kit. This Proform kit is a direct answer to that, and completely solved any cooling system woes on multiple high performance setups built here at GRW.

Our kit features the following

• Dual 12” Proform 2100 CFM Brushless Puller Fans

• Plug and Play Heavy Duty Relay Harness [With or Without A/C Clutch Integration]

• Threaded thermostatic fan switch

• Integrated Fan Shroud [Direct bolt-on for S30 Mishimoto Radiator / 280zx Radiator Currently in Final Development Phase as of 06.26.2026]

Now offering A/C Compressor function: Due to the growing popularity of our Vintage Air HVAC kits, we are now offering A/C compressor implementation into the fan harness. This will allow the fans to be triggered off of the A/C compressor clutch feed and run while the A/C is on, for maximum air conditioning efficiency. This works with both FACTORY A/C, and Vintage Air A/C systems.
