SpeedFactory Racing/BME Honda B-Series Outlaw Pistons | 1994-2001 Acura Integra, 1999-2000 Honda Civic Si, and 1997-2000 Honda Civic Type-R (SF-BME-218400) SpeedFactory Racing

1994-2001 Acura Integra, 1999-2000 Honda Civic Si, and 1997-2000 Honda Civic Type-R Outlaw Pistons by SpeedFactory

This is NOT just another piston labeled “Outlaw” with a couple of upgraded features. These were actually developed in our B-Series Outlaw car and proven at 90+psi of boost + nitrous = 2000+hp and 215+mph in the 1/4 mile.

Available for B-Series applications in 84mm, 84.5mm, and 85mm Bore sizes with 21mm & 22mm wrist pin size only.

More power = more heat. These pistons will cope with that better than anything else available. They aren’t meant to be the flashiest, lightest, or trickiest looking pistons – they are designed to be reliable at insane power levels. Period.

Years of pushing the absolute limits of these engines and our partnership with Bill Miller Engineering providing expert failure analysis and consulting throughout has led to this piston design which we are now making available to the public.

These are designed for max-effort turbocharged race engines making 1300+whp with an appropriate ~9.5:1 compression ratio for reliability.
