New Plans:
This build got some local attention, I may possibly be challenging more and more people with powerful 1FZ-FE builds, have to step it up. Lets see how far I can take it.
1. Camshaft Replacement (Bigger Camshaft, More Lift, More Duration, Same LSA):
The current Kelford stage 3 camshaft is great however, it lacks duration and lift. I need much more duration and lift in order to get the best high RPM power and peak power.
I talked to a sales rep from Brian Crower, I am going to get a custom grind, one that is based on their off the shelf stage 6 camshaft but instead of a 114 LSA it will have a 106 LSA.
With that narrow LSA plus all that duration, I bet it is going to have an extremally choppy idle and terrible low RPM drivability, much more so than now. But hopefully a much beefier top end.
2. Exhaust (Less Backpressure):
Just like I mentioned before, I was already planning to go with a larger header and a larger exhaust pipe.
This will have an even larger impact with this larger new camshaft.
Upon the arrival of the new camshaft, I decided I am going remove the electronic valve muffler and to go with a Magnaflow straight throw muffler with a 4 inch inlet and 4 inch outlet. This should substantially reduce back pressure.
So the plan is a larger 6-1 header with 2 inch primaries and a 4 inch collector from American Racing (identical to there off the shelf design but larger piping), a collector extension after the header, straight through Magna flow muffler, then dump. This should save a good amount of weight too since I will be removing the factory tail pipe muffler and the electronic muffler is quite large and heavy (since it is essentially two mufflers in one).

3. Ignition (More Spark Energy):
I found performance ignition coils that were originally designed for the 3UR-FE engine, they claim a 10x increase in spark energy. Decided ill try them out, hopefully they do something.

4. Solid Motor Mounts + Solid Transmission Mounts + Short Throw Shifter (More Power To The Wheels, More Consistent & Faster Shifting)
I found a local fabricator who can create solid motor and transmission mounts.
This should help with power via less energy lost through motor movement. Noticeable improvement? Hopefully.
Transmission mounts should help with via more consistent shifting, since it will keep the transmission locked in place.
Cons, lots of vibration in the cab! Possibility off cracking the block too?
Additionally, I also ordered a short throw shifter from PDI, this should help me shift faster (less distance between shifts).
They claim a 60% reduction in throw travel.

5. Lighter Pullies + A/C Delete + Clutch Fan Delete + Electric Water Pump (Less Parasitic Loss/Inertia):
I will cancel the entire A/C system, removing the condenser should provide better cooling since the air will go straight through the radiator.
The clutch fan will be swapped with dual puller fans mounted on a custom aluminum shroud.
I will swap the engine crank pully with a lighter one.
No A/C compressor and no mechanical water pump means I will only have a single belt.
The higher the RPM the higher the inertia and the more difference these mods will make.
