I have got a 2000 model Lc100 with an Inline 6, 4.5 EFI (1FZ-FE)

The cruiser has cloaked 400k Kms so far in the last 30k kms I have had issues with the auto transmission were in it slips from 2nd gear to 3rd gear. So I thought it would be the perfect time for a transmission and engine rebuild. At the moment the car is running on 285/70/17 Maxxis Bravo A/T 980 tires with Method Race wheels. The Lc has been lifted to 2" with a set of Dobinsons torsion bars, shocks, and rear springs. Everything else is stock.

I have a goal in mind and that is to have a minimum of 350 - 400 WHP plus keeping in mind that this will be my daily driver will need to get the best possible millage I can get.

I have already got the gearbox out and having it been worked on. The guys in the shop have got the solenoids and the gasket I am waiting for the clutch kit to come in stock. That should take two to three days. Thinking of also upgrading the valve body at the same time so that the gearbox is able to handle the added power. As soon as the gearbox rebuild has been completed will get it installed just so that I can have it tested and make sure it works fine.

Once that's done will drop the motor and have it rebuilt. My question is what should I do so that I can reach my goal of 350 WHP without the need of supercharging or turbocharging. Thinking of getting heavy duty Pistons, Connecting rods, Valves, Cams, and Headers.

Appreciate your honest advice since I am not technical enough and since I am having the engine overhauled what are the other things/parts I have to have it checked since the engine is out.

Thanks

Why not go with a turbo or S/C? The 1FZ from what I recall is pretty robust and can handle a little boost. I feel like you would be spending just as much on hard engine parts as you would a supercharger set up, with about the same gain from both. Unless your wanting to build the engine for fun, then I would go the charged route. Heck, if you have the coin, do both.
