Civic Type R Variations
The legendary EK Civic Type R was first introduced in late 1997. It arrived in the shadows of the already badged Type R of the Integra Type R and the NSX Type R. This EK has been at the forefront of an engineering marvel by producing a whopping 116horsepower per litre of its 1595cc naturally aspirated engine. But enough of the worshipping and lets look at the different types of cosmetic differences found in the EK Civic Type R mould.

http://www.dohc-vtec.net/pages/linke...s/pistons.jpegDifferent pistons are responsible for the compression ratio increases between 160hp & 170hp B16A and the 10.8 ratio for B16B. Readily apparent is the relatively modest change in piston top between B16A 160hp and B16A 170hp for the 10.2 to 10.4 change. However, the radically different piston top for B16B is very clear from the picture. The increase in compression ratio between B16B from B16A is 0.4.
The cut-outs on the piston top to accomodate for valve lift are basically the same between all three piston. This means the B16B camshafts can be installed into both 160ps and 170ps B16A without the need to change to B16B pistons.

http://www.dohc-vtec.net/pages/linke.../porthead.jpegOn B16B, the inlet ports are manually ported to increase air-flow. The exhaust ports are identical to B16A.http://www.dohc-vtec.net/pages/linke...es/valves.jpegB16B 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 170hp 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 25hp 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 15hp gain. B16B engine parts are available from Honda and with care, most of them can be used on B16A for good power gains.
http://www.dohc-vtec.net/pages/linke.../b16power.jpegThe camshaft profiles (wild cam) change from B16A2 and B16B are :

It should be noted that the B18C spec.R's cylinder block is used for its endurance.
