THIS IS STEP 1 TO BUILDING A 1000WHP HONDA B-SERIES ENGINE!!!
The line boring process ensures that all of the main journals are properly sized and in-line. This is critical at 11,000RPM and over 1,000 horsepower in order for the main bearings to survive. All of the caps must be ground first (in this case 0.005”) and the block must be properly positioned for this high precision operation. Vertical line boring eliminates the issues that plague conventional horizontal line boring operations or line honing operations.

Stay tuned and subscribe to our DSPORT channel as we will soon be releasing our B-series cylinder sleeving video. With a 72mm Class Limit turbocharger, the DSPORT B-series engines have produced over 1,060 horsepower (SAE corrected) at the wheels with off-the-shelf forged pistons and rods.
