The KORacing turbo kit is the best option if you want a complete bolt-on system. I am running my truck on the stock ECU with the stock fuel system at 5psi, and it runs and drives like stock, although with the BOV vented to atmosphere, the engine does drop to very low RPMs and almost stalls if you snap the throttle shut when driving slowly and with light throttle. This is easy to avoid by letting off slowly or by tapping the throttle before the RPMs drop completely - the other option is to recirculate the BOV (KO offers the option for just a bit extra). The kit is well worth the money, and the truck drives like a whole new vehicle - feels very similar in power to a friend's TRD supercharged V6 4Runner, though his is a tad faster (that could be my lousy 3.91 gears vs. his 4.30s, though).
I have dealt with LCEngineering, and they are a wonderful company (in fact, I buy a ton of different parts from them very regularly), but I would not recommend their turbo kit if you want something bolt-on because it eliminates the factory MAF sensor. I suppose you could fab up an intake pipe that allows you to retain the MAF, but the LCE kit is really designed to run with some sort of aftermarket engine management and a MAP sensor.
You can find the KORacing kit I purchased here - they have now added a 4Runner option on the website that includes the catalytic converter that you will need to bolt up directly to your factory exhaust, but you could also have an exhaust shop separate your factory cat from the stock manifold/downpipe combo and add a flange to it for cheaper. You can call Kris, the owner, to discuss all of these options.
I highly recommend the KO kit - as far as I know, I am the second person to install the kit on a 4Runner (the first being Kris' brother), but there are tons of people with Tacomas who are also running the kit, and there have been no problems that I know of.
