Jackson Racing's stage 2 upgrade goes straight for the jugular. Fuel management and timing duties are handled by a Hondata reprogrammed ECU. With VTEC engagement set to kick in at 1psi of boost (at any rpm over 2500), a stab of the throttle delivers an even larger dose of torque. Engine HP and torque are still rising at the stock redline, so we've raised the rev limit. After spending hundreds of hours on the dyno at Jackson Racing's R&D shop, B series engines can now take advantage of optimized fuel and timing maps, at boost levels up to 12psi. Stage 2 upgrade includes: Hondata ECU (w/Datalogging and 3 Step Rev Limiter), 440cc injectors, 8 & 11psi boost pulleys, belts and hardware.
