Here is another innovative part from K-Tuned.  For several years now racers have used electric water pumps to reduce the power robbing effects of parasitic drag from their engines.  By reducing the number of accessories the crank needs to turn there can be some impressive gains.  The K-Tuned Water Pump Block Off Plate system was designed to setup a K-series engine to run an electric water pump cooling system.  It replaces all the bulky and heavy OEM accessories with a simple lightweight aluminum plate.  The kit is designed to allow the perfect flow of coolant and also effectively release unwanted crankcase pressure.  The water port is sealed just like it was from the factory using the oem o-ring seal.  The breather port is threaded for an 8AN fitting and can easily be routed to any catch can set-up.

We have also designed an alternator bracket setup to be used with lighter Honda B and D alternators.  The 01-05 EM2 alternator is perfect to use with this kit because it will plug in directly to the K-series engine harness.  The EM2 alternators are also pretty easy to get and generally they aren’t too expensive either.  We have put together a series of kits allowing you to choose which parts you want, so you can build a system that works perfectly for your application.  This is a must have for serious race car builds and a true favorite among All Motor racers.
