If it is the real thing, maybe we can speculate on some stuff  So I said in that thread the 2 engines look like they're the exact same dimensions, so my hopes for Valvematic are dead (weep), and VVTL-i won't be there since it has that extra rocking arm thing which similarly takes up an extra inch on either side.
So this suggests this motor has Subaru i-AVLS or something of that sort, otherwise >200hp would not be so easy to do...which I am honestly surprised with since they said Toyota is reworking just about everything.
Another possibility is that the D4-S mixes air and fuel much better and allowed them to optimize the lift for high rpm operation... |
2 stage variable valve lift is dead. either you have infinitely variable lift like valvetronic or valvematic, or nothing at all... as for the FT, i dont think it will have variable valve lift of any kind. how do you make 200 hp? compression. high compression allowed by the direct injection portion of D-4S.
the mention of reworked bore and stroke also sounds promising. it just may turn out to be quite rev happy
