what do you have against milling the head for added compression? A B16A is a fairly high comp fact engine, that if you don't want a rebuild, a cheaper alternative rebuilding a perfectly good engine, is to mill the head
#1: Decreased valve to piston clearance.
Drag racers mill for many reasons, and with that they are either forced induction with dished pistons, don't have an interference engine, or use aftermarket pistons with larger valve reliefs.
#2: Makes cam timing a PITA.

I understand the tourqe curve, but what you aren't seeing is also what I'm getting at, the tourqe curve doesn't even show "real" tourqe until what??? 5500-6000 rpm???
Here is a dyno graph:
It has your beloved 1st gen b16, modded out with some Jun 2 cams. These cams make BAGS of torque. Nearly as good as Toda Bs.
Here is another:
Stock R.
Similar horsepower numbers, but look at the R's horsepower curve. Takes a big freaking leap up at 5500-6000 RPMs. Meanwhile, the b16 is still being its peaky ass self. Also take a look at the torque curves. The R engine makes 10 lb/ft of torque more. Not a huge deal. But look where its torque peak is. 6200 RPMs. Where is the b16's torque peak? 7250 RPMs.
I'm willing to bet that the R has greater area underneath both its torque curve and horsepower curve. Horsepower is no question, but torque is close. As it is, the R will walk your creation. With intake, header, exhaust on the R, it'll flatten out that torque curve, raise that horsepower curve a little, and eat you alive.

I wouldn't do this swap if I didn't KNOW that it would be faster or that I couldn't make it faster than what I have now.
I'm just curious about why either of ya'll can admit that a B16A w/ i/h/e a good bit of headwork, chipped ecu and VAFC AFTER dyno tuning was putting down 180+ hp and 110+ ftlbs in a TEG will run a better 1/4 time than a STOCK Type R that has 160+ hp and 115+ ft lbs...whether the tourqe curve comes in 1000 rpms earlier or not, THAT much of a hp difference IS going to come out on top. Soooo, why?
You won't get 180+ hp and 110+ lb/ft of torque. You'll have to choose between some peaky ass cams or something that'll give you torque, you cant' have your cake and eat it too.
Your previous projects were fast because they were light.
And please, if you are going to continue to argue this point, at least try out some punctuation, coherency, and a thing I like to call 'paragraphs.'
