Lol yep done! Got to find another cam, LS7 lifters, get this truck back on the road so I can get back to my car.
I've seen several LS1's make about 800 rwhp on 93 octane, bigger cube motors have made over 1,000. Not sure if they were VS gt35's or Garretts and also unsure of mods (internals, cam, heads, etc). I've also seen a few 5.3 motors run high 8's so they were making some steam with those turbos. I'd be willing to bet with you having forged internals, the right cam/converter combo, plenty of fuel pump/injectors and e85 with it turned up full tilt, it wouldn't be too far stretched to say you could make 1,000 rwhp? If not, probably pretty damn close? Maybe 850-900? This is all just me speculating of course, I could be way wrong lol. Just read a thread the other day where a guy made 750 at 22 psi on a 5.3, with twin chinese gt35's he said. It will be interesting to see what you make. It'll be no slouch that's for sure!

I think it will make more that 700, definitely should make at least 800 full out. I was told I could make 650-700 on my 5.3 with the same turbos, I don’t truly know though. But on a mustang dyno, I can see that being a problem lol. Maybe someone a little more knowledgeable will chime in.

Same here, that's mostly what I find is the cast t4 ebay turbos. But I have come across several t3 gt35 clones, not VS racing turbos but figured it was close. Not many documented VS racing gt35 t3 turbos out there, yours is the first in depth build I've seen. I definitely haven't seen any with the VS billet twins/1.06 a/r like I'm going with.

Started tearing stuff apart, intakes off, water pump radiator etc. also did some looking on the mounting of the new arb when it gets here, looks like I’ll mount the cross bar under the diff, arms forward and the. The links up to the frame rails, should fit perfectly! I got the 36” length bar thank god, not the 24” bar

Fired her up today, new cam sounds amazing. Unfortunately I have two injector o rings leaking and I cannot get them to stop. So no videos.
quartermax ARB showed up and boy you talk about a quality piece for the money. Damn nice craftsmanship.

Coming together nicely! Unfortunately I have to scrap my twin turbo G body project because the motor in my truck is screwed. So I'm putting the 5.3/th400 from my Monte Carlo into my truck and it's going to be a big single turbo street truck with a/c and power windows lol. I'll be following your build because I'm excited to see what those twins are going to do!
