The ct26 is capable of putting out 20psi max. Now each psi equals about 7-10hp. If we up the boost from the stock 10psi on each turbo to say 20psi on each turbo thats 40 psi total on a 2jz NA puts out around 240. So take 40multiply that by 10 you get 400hp add the stock motors hp which is 240 and you get around 640hp. The proof is in the math. Of course engine management/fuel management will be needed. But the stock turbos are capable of that mark. Now if I can only find that dam link.
I hope all that made sense. Sorry if that was confusing.

Your post is not confusing in the least, but your earlier post clearly said 650
whp. What you're saying
now (640hp at the crank) is still too high, but it's quite a bit closer to reality. The absolute maximum recorded horsepower figure for a stock us-spec 2jz-gte (including stock cams) with stock 2jz-gte turbos, an open exhaust, 20+psi of boost and race fuel is very near to 500rwhp through a 6spd (regardless of fuel or engine management). Driveline loss through a manual tranny is generally accepted as 15%, which gives us about 588.25 hp at the crank.
If you think you can build an Mkiv Supra TT with a bone-stock 2jz-gte and stock twins that will produce 640hp at the crank (a full 544hp at the wheels) then do so and you will be in the record books. Until then, the theoretical maximum for the oem 2jz-gte twin turbos on a
normally
aspirated (NA) 2jz-ge is irrelevant to Evilfurby's original question. I might also remind you that the 2jz-ge (NA) has higher compression than the 2jz-gte...and that the head is different so the oem twins don't bolt up to the 2jz-ge head.
I hope that wasn't confusing.
