MS is relatively easy if you want it to just control fuel, but as I'm sure you're after timing control, you'll need it on a turbo with a 9:1 compression ratio motor anyway.
You might see if anyone else has done it with this particular motor (isn't it shared with the Camry) - that's the best place to start...
The *other* piece of advice I can give you is that I'm done integrating toyota ignitions. The turbo 4runner that I have uses a plug-and-play harness that I built, no slicing of the factory wiring.. However finding similar projects, troubleshooting, and doing setup is very hard if you're the only one doing it. The only reason I see to do it is if your in CA and need to fool the smog guys or if you need to return your vehicle to stock. I'd strongly encourage you to weld on a crank-trigger ring and do a simple, reliable, EDIS-4 system instead...
