considering a stock 1uz vvti can put out around 260-270hp to the wheels with an aftermarket computer and a simple tuned exhaust (no intake changes, engine unopened), getting an extra 50hp to the wheels with basic cams and another 1500-2000rpm shouldnt be too bad
id still be VERY wary though of putting much faith in the earlier rods though if that is the plan. sure, theyre not as weak as the later vvti rods, but i wouldnt go hanging new pistons (they dont look the lightest either), cams, and heads around them, and expecting 8000rpm redline to be sustained. imho higher rpm NA use is more demanding on fatigue strength of components than lower rpm FI, so any experiences of folks saying how they made XYZ power on these rods without breaking is a bit of a false reassurance
just my 2c
