OK,
I work at a performance shop where we build all kinds of engine setups for all different kinds of vehicles. Now with that being said, our focus is mainly Ford powered vehicles, but engines are all basically the same. As far as the Toyota 4.0, I have a few things that I personally would look at. First question, are you planning on rebuilding the engine or just throwing it in there as is? If you plan on rebuilding, I've got a couple things I would suggest as far as parts...

Cometic Head gaskets
Cometic Gasket, Inc.

Elgin Cams

These are going to really help you. The Cometic gaskets are AWESOME!! We use them in our 4.6 & 5.4 Ford OHC engines. They have head gaskets available for your setup in stock. They will hold up to massive boost too!! Elgin Cams can custom grind/regrind/make you anything you want.
That being said, I'd like some more info on the engine itself. Are the pistons, rods, and crank all forged? If so then you have a great foundation to build on. At 10:1 compression you can do a few things...
My personal favorite is to have the vehicle run on E85 fuel. Yeah you have to put different injectors in there with alcohol compatible seals & the same for the fuel lines & pump. But, E85 LOVES compression. Both mechanical & artificial (boost). There are some guys here in Texas with STOCK brand new Z06 Vette's that are twin turbo'd with NO INTERCOOLER (E85 removes basically all the intake air charge temp, remember it's alcohol!!) running into the 9's. Stock motor! Just converted to run E85 fuel to help the 13+ lbs of boost they're pushing on that 11:1 motor. I don't know if they have E85 in your area, but it may be worth it to search it out. That would be what I'd do.
Or you can rebuild the motor to about 9:1 compression and boost the hell out of it. I'd keep it about 9:1 so you still have some off boost power. We have built 650hp 2.3 based engines with this compression and they were VERY streetable (Beasts on boost though!!). I'm sure you have a very capable engine builder in your area who can help you with all the specifics.
If you want to stay away from turbochargers and go supercharged, go with a Whipple/twin screw supercharger. It's extremely efficient and you'll make TONS of power. They're a little pricey though, but they're worth it.
But remember, it's all about the cubic dollar. There is a direct link between how fast you wanna go and how much you wanna pay. Hehe That's always been a problem for me...

Laters,

Brian
