Pictures of the Old Civic Type R. This was a 1.6 VTEC and used the B16B Honda engine producing 185ps @ 8300rpm. Not ever offically imported into either Europe or USA, some JDM models are seen in the UK (occasionally). Check out the Best Motoring video, battles @ 10,000rpm

General stats for EK9 Honda Civic Type-R
Performance figures for JDM Honda Civic Type-R
Have you ever wondered how fast the Honda Civic Type-R is in a straightline ? In the May 1998 issue of UK’s Performance Car, a true JDM Honda Civic Type-R was tested in a special hot-hatches feature. The figures attained will send shivers down any of our competitor’s spines.
A listing of some of the critical standing acceleration numbers are as follow:
Top speed was not tested as all JDM Hondas are speed limited to around 180-190kph.
The Civic Type-R bested the UK version of the Honda Integra Type-R which has a derated 190hp engine (and similar quad headlights front facial of the US version). The UK’s Integra Type-R obtained values of around 6.2seconds for the 0-60mph dash but a faster 17.1 seconds for the 0-100mph dash. However, the Integra Type-R was not fully run-in at the time of its test.
Highlights of B16B 98 Spec R compared to B16A
In order to increase the power output by 15 hp, and the max RPM by 200RPM, the engine goes through many upgrades. It should be noted that the B18C spec.R’s cylinder block is used for its endurance.
The translations for the numbered labels in the diagram are:
- Cylinder Head – Complete port & polish
- Exhaust Valve Spring – High-lift, dual-layered spring
- Sparkplug – High-heat-type #7 platinum plug
- Pistons – High-compression, low-friction, custom pistons
- Connecting Rod – High-output, high-durability, lightened, custom conrod
- Engine Stiffener – Aluminum die-cast, high-durability, one-piece type
- Crankshaft – Full-balancer, 8-weight, high-output, custom crankshaft
- Inlet Valves – Lightened inlet valves
- Inlet Valve Springs – High-lift, flat-surfaced, dual-layered spring
- Camshaft – Wide-angled, high-lift, high-durability camshaft
- Intake Manifold – High-RPM type.
Engine specifications between B16A and B16B:
The camshaft profiles (wild cam) change from B16A 160ps to 170ps and finally to B16B are:
The cut-outs on the piston top to accomodate for valve lift are basically the same between all three piston. This couldmeant that B16B camshafts can be installed into both 160ps and 170ps B16A without the need to change to B16B pistons.
On B16B, the inlet ports are manually ported to increase air-flow. The exhaust ports are identical to B16A.
B16B intake valve seats are at a different angle to B16A, 45 degrees vs 60 degrees. The intake valves are also different, being lighter and having a thinner valve stem.
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).
You can use any B-series transmission (cable or hydraulic) with any B-series block as long as you make sure that you use the correct clutch, flywheel, and intermediate shaft.

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.
