Seems like you could rebuild the engine, buy a rebuilt transmission from toyota and the supercharger for the amount of money and time to do the swap.

It does offer more power, and the ability to go forced induction on top of it, although then you are talking some real costs since I don't know of any pre-made kits like our 4Runners have. If you can get one with the VVT-i technology, it puts out roughly 290/300 HP/TQ. That's a big jump over our stock 183/217. The supercharged 5VZ-FE runs at 265/267 HP/TQ so even that cannot match it, however it's comparing apples to oranges. An engine swap like the 1UZ is an insane amount of work, whereas putting a S/C is not and can be done in one day with basic tools. Costs would be about the same if you are doing all your own work and labor but time costs don't even compare.

Headers will. Doug Thorley headers will gain up to 13 lbs/ft of torque. However, the cost and absolute pain of installing them takes out any fun factor of installing. There's a general rule of thumb that you pay roughly $100 per HP on a naturally aspirated engine and I've found that to be true. The only one that can beat that price point is the deckplate airbox mod, but it's not about to turn your 4Runner into a race car by just freeing up the intake a little.
