John's JDM Honda K24A 818R Rebuild

[Hobby Racer]

I finally got the serpentine drive belt system worked out and completed. I finished welding the supercharger mounting bracket and fabricated a needed idler pulley at the top so I could run the original accessories and keep the factory belt tensioner. Most people get rid of the water pump, pump housing, alternator and belt tensioner when they swap in a JDM K24. This is because they are different from the versions that come on USDM K24's. I figured I would save some time and money and use the JDM stuff that came with the engine. If something fails down the road I still have a complete spare engine to pull parts from.

I modified the factory front engine support bracket to use as the base for my upper idler pulley. I had to support the pulley from the opposite side as all the other pulleys since there was not enough clearance on the back side closest to the block. I experimented with multiple pulley positions and settled on the current spot.

Now I am just waiting for the new belt I ordered to arrive. I hope it is a perfect fit. I also added a smaller crank pulley from a JDM K20 Type-R motor. it's lighter and smaller and drives the accessories slower, generating less parasitic drag.
