Transmission: S4C With Helical LSD (4.1 final drive, dual-synchromesh on 2nd, 3rd and 4th gears)
Vtec engagement @ 5800 rpm
ECU code: PCT
Note: This engine uses the same block as the Integra Type R (B18CR), which is taller than the B16a block (by approx 17mm), but with a crank the same stroke as the b16a. It uses longer rods to accommodate for this, which is why the Rod/Stroke ratio is higher than a standard B16.
The B20A3 and B20A5 are not considered part of the B family. See Honda B20A engine.
