TracTuff K Water Pump Housing Delete
The K Series water pump housing delete is designed to take the place of the heavy OEM mechanical water pump housing, water pump, and thermostat assembly. Sought after for the decent weight savings but mostly chosen for the HP freed up! Significant reduction in parasitic drag the motor experiences turning the water pump and further gains from not turning an alternator for those that opt for just the plate! Additional benefits include eliminating pump cavitation during sustained high RPM use, programming the ECU to turn the pump off for short periods where you don't want/ need water movement in exchange for more power by means of less load on the charging system, and then being able to keep the pump and fan on to cool the motor while the engine is off.
CNC machined from US milled 6061 aluminum; the plate incorporates an OEM o-ring groove and a large 1-5/16"-12 SAE (-16AN ORB) inlet port for great water flow and hassle free fitting clocking. The breather port is a 3/4"-16 SAE (-8AN ORB) port and was chosen because the factory crank case chamber is already rather restricted and larger fittings really wont do much but empty you wallet faster.
In late 2018 I redesigned the alternator mounting bracket due to some untimely failures that were ultimately traced back to the use of a specific alternator (D17 from the EM2). It was beefed up significantly (you can see V1 in the images below) and now includes a bolt and nyloc-nut rather than the special square Honda bolt and nut. The difference being, the special square bolt and standard nut from Honda allowed the installer to continue to tighten the nut against the two piece EM2 alternator, which compresses, until the mounting bracket tabs were pulled inward... almost to the point of failure and when mixed with heat and vibration, ultimately lead to random failure. The new combo is torqued to yield and the nyloc nut is used to ensure the bolt does not loose tension and back out.
The tensioner assembly is also machined from 6061 aluminum and uses US made QA-1 rod-ends and stainless steel jamb nuts. The tensioners adjustment range works for a vary large number of the alternator pulley/ crank pulley combos... but its not always perfect. I say that its not always perfect because there are several factory and aftermarket crank pulley diameters as well as various generations of B and D series alternators, making the belt length unique. As a result, I'm reluctant to sell belts... I much rather sell the kit without and let you determine the belt length based on your specific choices vs. selling you a belt and then you having to either change the crank or alternator pulley... or shorten/ lengthen the tensioner.
NOTE: The new alternator mounting bracket design has been created to address the issues associated with installers over-tightening the alternators pivot point; mainly an issue w/ the D17 EM2 alternator and it its ability to collapse/ give. The new mounting bracket is 60% thicker which allows for more initial torque (bolt to mounting bracket) and a nyloc-nut that can be torqued to keep the hardware from loosening.
Various alternators may be used with this kit but due to slight variations in design... a very small amount of material may need to be removed from the alternator or the bracket to work with each other. Late model B and D series alternators with a ribbed drive pulley fit the bracket without any extra effort. The 2000-2001 DC2 Type R (B18C5) has the 2nd. highest amperage output and the 1999-2000 Civic Si (B16) or 2001-2005 Civic (D17) have the lowest amperage. If you are looking for the highest amperage OEM option and you are either willing or able to modify the lower mounting ear of the alternator as well as buy a reducer bushing for the upper ear; I recommend the 2000-2009 S2000 (F20C/ F22C) alternator. The S2000 alternator conveniently has the same number of pulley ribs, rotates the same direction, and has the same plug as the K.
Due to the various K series crank pulley diameters (OEM & Aftermarket) as well as multiple alternator pulley diameters... I cannot provide belt lengths for every combo. The tensioner in this kit does allow for a wide range of adjustment, and in many cases the two belts I stock, work. You just need to decide if you are looking to use a 4 rib or 6 rib alternator. If you choose to buy a belt from me and it doesn't work for your combo, you can return it for credit. If you would rather determine the belt length on your own, simply wrap a string around the pulley's of the installed kit, mark where the strings touch, measure that length and call an auto parts store with the length and number of grooves.

* Buy one from me, use one of these numbers, OR use them to cross-reference to another brand. I will not do this for you.
I offer an electric water pump mount for the Meziere WP136S electric water pump as well as a electric water pump hose kit to get water from the pump to the water pump delete plate. If you plan on ordering the electric water pump hose kit, do not select any inlet port fittings here, you will be asked to choose fittings with that product.
