i can completely relate to your thinking. Because a few months ago i was thinking exactly what you're thinking. I even thought about getting a integra LS 5th gear because the RPMs were so high.
Here's a quick lesson that will help you understand it.....
each RPM your pistons are moved all the way up and all the way down. the b16 has a very short stroke of 77mm so each rpm the pistons go down 77mm and back up 77mm. So that means that they move a total of 154mm each rpm. The b18b/b18a has a stroke of 89mm so each rpm the pistons are moved 178mm
so let's say that when your crusing at 4500rpms that's 4500 x 154 = 693,000
now lets take that number that we get when we multiply RPM x STROKE x 2
so 693,000 divided by 178mm (from the 2 times the b18b/a stroke of 89)
693,000 / 178 = 3893.2584 RPMs
so your b16a's 4500rpms is equivalent to an integra LS crusing at 3893.2584 RPMs
So there you go. Yes your cranking out the high rpms, but your motors pistons move significantly less each RPM than your average motor.
hope this helps.
