OEM Honda K20A Short Block – 900HP Capable | Built by SpeedFactory Racing

This is not your average short block — this is a freshly rebuilt, competition-ready OEM Honda K20A short block, built in-house at SpeedFactory Racing by engine builder Kevin Kempf. Designed for serious boost, this engine is ideal for high-performance street builds or competitive drag racing.

At the heart of this build is a AEBS Closed Deck sleeved block, with internals rated for up to 900 horsepower. Every component and machining step has been carefully selected and executed to deliver maximum strength, performance, and reliability.

Once the order is placed we will build the engine in house using the bore size chosen.  Turnaround time should be 1-2 weeks max.
