I see your vision bro
Unlike a lot of cookie-cutter shit out there I'd do it just to learn and see what it's about. The only difference is if your building a TQ monster you can't afford to go budget on the front suspension, rear suspension and tires or you will blow through tires and still be going nowhere fast. Could be a monster from the roll though. You get big displacement.
If you can make the TQ stick you won't need to worry about revs as much as less displacement setups - 6500 isn't the best but if you can shift fast and then smash some more of that TQ down on somebody's ass you will still stretch them. People don't understand that you don't NEED revs when you make torque. (diesels, v8s, etc).
Personally... if you don't go for it let it be b/c you don't want to - not b/c people say it's stupid. You're always a vtec head away from more HP and more TQ just like my non-v build. I already have a built GSR head ready for action IF I needed to prove a point to some1. But I'm having fun competing w/ the vtec guys and smashing on 'em too! I built what I wanted to build despite what people said bc I stopped bulding shit for every1 else's approval years ago and started building what the fuck I wanted to build - the proof, serious D16 EG in the making as we speak - and YES all-motor.
Good luck w/ the build man and I'd love to see it come together. You're surgical w/ your research - I've seen it in action - spreadsheet junky just like me - not just doin' shit off the top of your head. As long as you keep that approach it's impossible not to be happy. And at the end of the day - when the hood is popped in a parking lot you actually get to teach people shit b/c it's not the same old shit they see every weekend.
