And this is all on STOCK Internals with basic turbo swaps.
In the name of fairness I think the FFTEC numbers should be accurate. The last dyno log I saw was 659 WHP and 561WTQ. Not really fair to short them 40 HP and 100 TQ

Very True, but some are inherently easier to make a lot of power than others. A good example is our N54 versus the E92 M3's S65...it's just a lot easier in terms of resources/cost to make more power.

From what I have seen so far, we are pretty capped at around 450ish WHP for our stock motor setups and 650ish WHP for turbo upgrades. Bolt-ons it seems 650-700 WHP is our limit. I am curious what FBO 2jZ and Evo's are doing.

I think you should mention that those RB numbers include head work, they are pretty astounding though nonetheless.

Sadly we don't know the limit Shiv's e85 Fuel system in his test car was making around 700whp, but he wasn't really pushing it as much as he could have been. I just want to know at around what power level this motor pops!

Stock turbo 2JZ supras tend to hover around the ~400whp and stock turbo 4G63/4B11 EVOs are ~350whp.

So we're already doing better lol

I think a little more displacement would t hurt tho! - even if its only worth another 50WHP at the end

Fair -- I just quickly google'd & got those numbers. I also wanted to avoid numbers that were created by running race gas/meth (wanted to keep as accurate to mod created power as possible).

Like others have said, the bore & stroke for the N54 is good as is & until people have crossed the upgraded internals "bridge", increasing displacement and altering the block is ways away.
