Dood, that blower sounds SICK! Here is what I would advise, after dealing with a supercharged 5vz-fe in an 88 4runner:
Guages. Seriously.
I got an XD-1 AFR wideband gauge from URD and it has been very helpful.
I have a dual EGT guage from westach. It is a little on the analog side, but hell, the green backlighting and the analog feel go well with the old 4skinner. Depending on your level of analness, you could get away with just one EGT guage, but judging by your build, having a pyrometer on one of the inner pistons on each bank is good peace of mind when boosting.
I don't know what you've got for oil pressure, water temp and fuel pressure, but as listed, in my opinion of being boosted, they are in order of importance, with fuel pressure coming in a distant 3rd. Usually your AFR guage will tell you if you're running lean. I went with a dual oil press/water temp guage from westach, to keep the retro theme going, and they really are good folks.
Its a pain in the ass to hook up all of those guages, but the peace of mind after putting so much time and money into a project is very much worth it. It was to me at least.
You may want to get with Gadget from URD concerning the tuning of your supercharged engine. That thing is going to be an absolute BEAST when you get it all tuned up. Resist the urge, at all costs, to romp on it until you've got all of your fuel and timing maps at least safe and have some decent monitoring of your engine.
I remember when I slapped the smaller pulley on my supercharger, the whine got much higher, sounded better and pulled as hard as my 2001 Nissan Maxima, which was no dog. It was almost scary to be on 32s doing that!
Props man, enjoy it!! Your pig is an inspiration!
