Of course there's room, but that's not the point. The point is that a big heavy low rev engine is not exciting, and a sports car needs to be exciting to make up for the "lack of value". The J35 has a 93mm stroke, so it's not going to be much good above 7000rpm no matter what you do to it.
The VQ37VHR is not just a VQ35DE in a higher state of tune. It's newer (newer combustion chamber design), has VVEL (huge benefit), and has higher compression ratio and higher displacement. Take those into account and you realize the VQ37 isn't all that tuned up.
For a mid-upper tier sports car Honda should be looking into either something like a new F20C or a 2-2.5L V6 that revs just as high. If the lowly Civic can get an 8000rpm capable K20, they should be able to do this. All they need to do is bring together the best of the engines they've made before: 3 stage VTEC, high compression ratio, the new direct injection systems, new variable speed oil and water pump, shortish stroke in the 80-85mm range + nice long forged rods, and it'll have silly power, great sound (NSX revving up = pure race car), great fuel economy. And torque is for old people driving Mercedes Benz, gtfo.
