Node, 3vz-e ecu is actually pretty easy to work with. All the OBD-I ECU's are dreams with piggybacks. (I got 680's to run "OK" on a 3vz-e & 720's on my 3vz-fe)
(Open loop / cloosed loop OL/CL)
Because they don't use fuel trim in OL, they can't change OL, and it's closed loop not only is not as sensative - but it is easily defeated - it won't suffer from the problems OBD-II does. & has more advantages than even most smart people realize AFA tuning "big dumb changes". LoL!

Guys, questions like "how much boost", or "how much power" are going to fall under an irrelevant, or unanswerable answer the way most people ask the questions. So I'd like to take this opportunity to stomp them now so they don't get out of hand flooding node with questions. (No offince, common questions, that's why I'm shooting them in the foot before they're are bunches of them)

1) power is a direct function of the mass of the charge the engine can inhale - not what pressure it's at. Pressure is important (later on) but extremely mis-understood & mostly irrelevant when you're talking power between setups.

2) power production is entirly open ended. It could be anything you want to make it, because you can sling anything on you want slung on (that will fit within reason). As with #1 your mileage is going to varry widly based off what you choose & how you run it. While one compressor may move 50 horsepower worth of air @ 30psi, another may make 15,000 @ 5psi.

Power is an unanswerable question - without a specific question asked. Don't go crazy asking about power output until you've read a few basic forced induction guides (turbo, supercharger - anything helps - just google a few! Takes 5 min to read & understand the majority of the basics.)

That being said CT-26's are large node. Two supra CT-26's would wind up being well over 600bhp @ 10psi on any of the car dohc v6's. Most likely well over 500bhp @ just 5psi.

Node I think you should just cop out & grab your generic t3 flanges & weld them on. You can size them down to 42/48's, up to 60/48, 60/63 & super 60/63. Or even go t3/t04e hybrid (avoid t04b like the plauge - ancient things - nasty blaaaaah). t3's are really cheap too. (Not that my new ct-26 off ebay isn't in a dirty - but mint condition & $66 LoL!)
I've done the math a billion times for the 3.0L v6's (3vzfe / 1mzfe)
That t3 flange list when you go twin turbo sports everything between 260bhp - 440bhp stock t3's, & 700bhp for a T04E-60. That's just 1 bar of boost (14.7psi). Assuming the grunt & turbine side to spool the turbos to a good capacity, and flow that amount of exhaust.

I just think t3's would give a waaaaay better fit in most regards. (Sizing, compatibility, avalibility, price, part & misc fittings avalibility.)
