Back in 2006 K-Tuned originally designed their K-Series Water Plate Kit that ran D/B Series alternator. They have revisited the project to breathe some new life into it. K-Tuned constantly strives to improve and bring the very best to their customers and racers. The original design is still for sale today and that will not change. However, they have brought some nice new options with the ability to run a k-series alternator. The V2 kit can be installed on your original K-Tuned Water Plate *EXCLUDING* some original designs for those who want to upgrade to a k-series alternator. 

For several years now racers have used electric water pumps to reduce the power robbing effects of parasitic drag from their engines. The reason is pretty simple, by reducing the number of accessories the crank needs to turn there can be some noticeable and impressive gains. The K-Tuned Water Pump Block Off Plate system was designed to setup a K-series engine to use an electric water pump cooling system. It replaces all of the bulky and heavy OEM accessories with a simple lightweight aluminum plate. The original alt bracket setup was designed to hold the older and lighter B or D series alternator and works well. The only difference is a little extra work for installation, so we decided to design a compatible alternator bracket setup that works with the original oem K-Series alternator. 

This updated kit features a fully adjustable tensioner with an integrated pulley that mounts cleanly on the left side of our original Water Plate. The lower alt bracket then easily bolts up to existing holes on most K20 and K24A engine blocks. The result is a setup that is much simpler to install, with no additional parts or wiring needed. With the new version of this kit, they have upgraded their mounting hardware to include a larger ARP upper alternator mounting bolt, as well as 2 sets of larger bolts depending on which style K series alternator you have, for the lower mounting bracket. There are 2 mounting positions available to allow proper fitment with most stock crank pulleys. For the alternator, they made a lightweight CNC machined 6061 billet aluminum alternator pulley to replace the heavy oem unit. They have also included a custom length 7-rib belt, that fits with most oem crank pulleys and all hardware for installation. As a final bonus, check out their custom billet water pump bracket, it has been designed to hold the K-Tuned electric water pump right beside the plate setup. Just like the other brackets, this bolts up perfectly to existing holes on most K20 and K24A engine blocks. K-Tuned can now confidently say that the K-Tuned Water Plate Kit is more complete than ever.
