566whp 300zx on 91 with stock heads
Here is a very interesting build that was recently finished. Very similar to what I plan on running in the future.
Twin GT3076s, built bottom end, stock heads.
566whp at around 17psi with 91 octane, no meth, no nitrous, no intercooler spray, etc.
A very conservative amount of boost and timing for that setup, it will last for years and years like this.
With race gas this setup will push 900whp+ numbers. I would of built the head but he probably wanted to maintain stock-like driveability.

kinda laggy for twins, look how long it took to spool (boost line). but good numbers for pumpgas.

If he had heads with a somewhat aggressive cam he would be 600+ easy. With 93 this setup would be even more potent.
Z1 motor sports has laid down 1000+whp with twins like this, I think they were smaller though. (3071)

Here is an idea of what the vg can do with just boost on race gas:
That dyno is of Specialty Z's EXP-90 kit that utilizes two GT3071r turbos shown in red, overlayed on top of their old kit that used two GT28RS turbos. It is much more like stock as far as turbo location and charge-pipe plumbing.
They are working on a new setup that uses the GT3076's.

Greg Dupree, who is the owner of Specialty Z, is currently fitting the GT3076 turbos and some nitrous.
Here is the EXP-90 kit (3071s) on a customer car with supporting mods and 150 shot of nitrous. The timing belt was off one tooth and it was still this strong. He is planning to dyno again soon now that the timing belt has been fixed. Went from 740 to 838 on boost alone by putting the belt on correctly, so nitrous numbers should be even better than before:

Z1 motorsport's convertable Z (I think it's ugly):
Uses two TD06-20Gs + 260shot nitrous. They are currently working on a more modern setup with bigger turbos.

Ok, those are some just stupid strong cars.
Any pics of some nice looking exterior mods on the Z's?

My car, it's pretty ugly right now and is awaiting SPL suspension:

^ Not a bad looking ride. I wonder why the Supra gets so much more love?

I will say the VG is easy to pull once you get the tranny, boost hoses and radiator out, it is basically like a square you can lift straight out. The I6s are a bit trickier because of how long they are.
