On the left are the power curves for B16A 170ps versus B16B. Note the big gain in power after 6000rpm, the VTEC switch-over point between mild and wild cam profiles. The gain at extreme high rpms is readily apparent on the curves.

Various individual specifications for B16B can teach us about the feasibility of various modifications to B16A. For eg, the throttle bore diameter for B16B is identical to B16A at 60mm. This means that enlarged throttle bodies for B16A might not be an optimal mod or that a compromise in power delivery might result, eg loss of low-end power in return for gain in high-end power. Note that B16B has identical low and mid range power as B16A.
As with B18C Spec R, the wonder of B16B is the assurance of a 15 to 25ps gain in power on a B16A provided the tuning done by Honda can be completely replicated. Nevertheless even if only a portion can be duplicated, combining with properly designed aftermarket exhaust, headers, and intake could still potentially realize this 15ps gain. B16B engine parts are available from Honda and with care, most of them can be used on B16A for good power gains.


Honda Gearbox Ratios

The table below details the gearbox ratios that can be found in all of the different JDM (Japan Domestic Market) B series transmissions. It also details whether or not the transmission is available with an LSD (limited slip differential).

Obtaining ECU Error Codes

To determine if your ECU has an error code:

Locate the ECU under the carpet in the passenger foot well.
Find the red LED in the center of the ECU.
Turn the ignition to ON. The red LED should flash once when this happens to indicate that the ECU has power.
If there are no further flashes then there are no error codes.
If there are further flashes then there are one or more error codes.
