lol dont quote the numbers of a different engine, no matter how similar there is ALOT more to the vhr as you said its newer tech, which means more complicated and shops are still figuring out the vvel system meaning your going to spend 10x for R&D then what you would for a production harness.
350z with a lsx(all the block dimensions are the same minus warhawk and gmpp lsx block which have a little taller decks.)
now vq35hr(vhr is even bigger)
as you can see its exactly like i said, dohc is friggin huge it requires a much much larger deck and heads.
henessey and one other company offers modules i cant remember the other company neither of them have been used succesfully with the vq35 engines in any chassis.
no not more complex the next gen engines are going back to variable valve timing on exhuast and intake(aka backwards) and direct injection to make more power from the same displacement. hardly more complicated or new, also the gtr was in development BEFORE the gtr try again, not assumption but fact, just like the future engines for the z are going to be direct injected or diesel nissan already said they where ditching vvel not a single platform is scheduled to receive it in the future.
you said you want it to pass inspection, which again best bet is lsx e rod kit, just because the light isnt on dosnt mean you pass since so many systems rely on each other, for instance unplug the bcm on a 370 and guess what happens? throttle body dosnt work even though its controlled by the ecu, everything is interconnected, dosnt matter what you want it matters what is required for the system to function.
you can do what you want i told you what is required, just because you dont like it dosnt change the fact thats what has to be done,(btw might wanna look into those swap harnesses some more, you cant just put the engine in, plug up the harness and computer and it runs, call em and ask em they will tell you themselves those swaps wont pass any inspection)
