unless you go the 7KE manifold your only other stock option is the 4KE. the 4KE isn't that bad considering the runners are only a couple of mm larger diameter than the large port 3K heads.
200hp at the wheels? probably not at a toymods dyno day..or in 4th gear... my motor made 47.3kw at the wheels at DD5 compared to 86kw 4AG's making 55kw. so you are looking for 150kw rw?
that's around 233 flywheel kw, or 312 hp
that equates to 274Nm at 8000rpm
say you wanted a more sane 6000rpm power peak, that requires 365Nm of torque.
for a motor with 100% efficiency to do that you'd need to be running about 1.1 bar boost at 8000rpm or around 1.8 bar boost at 6000rpm. given that the corolla motors will be closer to about 80% efficiency, add another 20% to that boost.
so that's 1.3bar boost at 8000rpm (19psi)
or 1.6bar boost at 6000rpm (23.5Psi)
sounds like you'll be needing to do some serious work to the head to get it to flow those kind of numbers (350CFM at 19Psi, or 300CFM at 23.5Psi)
i think you'll have to end up going to a custom manifold.
hmm that brings another question. could a K bottom end or block withstand 365Nm of torque? i guess we'll see
