What can you do with the VQ37VHR, without going totally nuts and keeping stock drivetrain reliable?
On E85 the engine put down almost 367 wheel hp and 293 lb ft of torque, or about 440 crank hp! That is serious power and torque for a streetable 3.7 liter NA engine, just about 100 whp per liter! This was the most powerful NA 370Z that Specialty Z has tuned to date.
Actually, was thinking something mild over stock, for a small bump in power. For example I threw my Silverado on the dyno just to clean up the mapping, as it was running too rich. Went to 89 octane and rest is stock. Got about 8-10% peak power increase and mileage went up 1-2 in the city, lol.I mean it depends you can go NA with E85 and higher compression and cams. This would be my choice given I like tracking cars.

The new tune took into mind our much bigger exhaust cam, higher compression, better flowing heads, headers and intake manifold. Sebastian was able to use the VVEL system to act…motoiq.com
Lots of guys have run superchargers on these and the earlier 350z from Stillen. The issue is keeping IAT's down. And the self contained superchargers tended to blow up during track use as they would overheat.
Not being satisfied, Sebastian kept at it until he reached 441.99 hp and 350.94 tq at 6620 RPM. - 91 octane
he results for our 100 octane map were 483.96hp and 378.15 tq at 6790 RPM. That ought to be enough to turn our tires into dust!
Finally, Sebastian dialed things down a notch for a 98 octane map at 467.66 hp and 369.38 tq at 6800 RPM.

Being honest you are going to get way more bang for buck on the domestic side or just going to a used GT-R if you want 600-800hp out of these. Twin turbo kits easily get into the 10-15k range once you are done with all the little bits and bobs that eat up a turbo budget.
