Power upgrades for the 1FZFE... keeping it naturally aspirated

[HunterMcC1]

Update on the project... 02 sensors have been moved to the stock exhaust manifolds for now and they will be placed in a similar location in the header... in the collector for each bank... which brings up another question, does this motor run like the old F/2F where it likes some back pressure (muffler/glasspack) or does a straight pipe off the header work? Thanks for the updates

I am new to the 1FZFE and had a few questions about it. Just to keep things Toyota, I put a 1FZFE in my FJ40 to race in our local mud bog races. Rules state that my motor class (4 and 6 cylinders) must be naturally aspirated, so my question is, what kind of power upgrades are available for this motor with out turbos or superchargers. I should also clarify also, this is a 94' 1FZFE, pre-OBD-II I believe... although there is a 'diagnostic' port attached to the motor. Any help would be greatly appreciated.
