  • Sale
  • Regular price $4,249.00


These shortblocks are assembled using BRAND NEW OEM cores and crankshafts sourced from Honda directly.  There is no need to send in your factory engine to be built. You will receive a new block and crank.

There are a many ways to combine parts and machining to achieve specific goals. We have built many K20C's from top to bottom using nearly every parts combo available. That being said, our preferred parts combos are hand-picked to meet and exceed the goal listed. 

Our main focus is to keep pricing within reason and to only sell our customers the parts that are needed to get back on the road/track.  The best way to do this is to offer "HP targets" for blocks with different options. 

This block has a build time of 1-2 weeks after order is placed before it will ship. Due to variables with each build, we don't typically keep these on the shelf, unless otherwise noted.
