b18c1 block w/ a b16b head = one of the best setups out there.

...for boost. Throw a Type R exhaust cam on there too.

the thing about rocking the d is you get to a point and just cant go any further because of the less aftermarket support. with the B there are pretty much endless possibilities

This isnt even a fully built motor. The possibilities are endless on a D too. Sleeved block and built, ya can take it over 350WHP.

Yeah, but those possibilities run out of breath quicker than on a B-series...

Why just the exhaust cam? Does it stay open longer? Because thats the only reason I can think of...

The extra duration and lift will spool the turbo faster. However, if you use both the intake and exhaust cams, you get valve overlap. This is beneficial to NA cars but actually hurts the performance on a turbocharged car. Generally, the most cost/power effective combination in an NA application (without going aftermarket) is an ITR exhaust cam with a CTR intake cam, since the CTR uses higher lift and longer duration on the intake, but the exahust cams are nearly (if not) identical.

I thought that was the deal with the cams. Ive heard a lot of people saying to get the Type-R exhaust cam, and wasnt always sure why, but it makes sense now.

my point exactly

the CFT Si is running a GSR at 750whp and is only at about 10.1 (i feel stupid saying 'only 10.1') but there are civics out there running low 9s

if you think about it it makes sense because some of the compressed air that hasnt combusted yet excapes through the exhaust valve, and it reduces the turbos efficiency.

is this true also for super charging, how would you set those cams up?

Well, on a supercharger, the extra exhaust duration is not necessary, since there is no turbo that needs to be spooled. Valve overlap is still a no-no, since you're essentially just wasting some of your boost. However, as with any motor, extra flow both into and out of the engine will be beneficial.
