Is the VQ35HR that much better than non-rev up?
Honestly, I think it depends on what you want to do with the car. Daily drive? Autox? Track? Drag race? Street race? Cruise? It does matter, at least that's my opinion. A DE with bolt-ons can make ~260whp. An HR with bolt-ons can make ~300whp, all things held approximately equal. An HR weighs at least 100# more than an equally-optioned early DE. My CHEAP DE weighs ~3060# and has 260whp, and can keep pace with a modded HRs and a modded 370, for example.

Don't forget, you're trying to compare a vehicle that was rated before the SAE horsepower certification standard took effect in 2007. A rating of 287 HP in 2003 would be closer to 270 horses by today's SAE standards. A SAE-certified 306 HP would have been something like to 320 horses prior to 2007. Therefore, you're looking at something closer to a 30+ horsepower gain from 2003 to 2007 with the HR engine.
Learn something new every day, hmm.

I personally drive a 04 Touring... I mean really would I get rid of mine for a HR just for extra Hp.. Hell no. I do like other things about the newer 350's.. interior, hood, headlights/taillights.. but if you look at a complete package instead of just going fast.. you might want to consider a fully loaded older Z instead of a stripped newer one.
oh to add.. my old man just bought a 370 with the sport package.. the rear looks like Porsche Boxster.. and the front looks like a demented catfish with maxima headlights... nice interior, brakes, and wheels.. but thats about it.
