Is there a way to run without a AFM? It seems like life would be a whole lot easier.
Hehe... Me = noob
Sometimes
It seems like if you were to run standalone you could run something different than a AFM. Such as a MAF off a newer car or such.

T3 "Super 60" does 35, so you sure it was "38" and not "28"?

That makes a LOT more sense!

Hell, give them a shot...according to those specs they are bigger than they looked (to me). I guess I'm just used to looking at the "huge" (relatively) turbos on rotaries.
They're good for ~400 whp on a Z32...I couldn't find any info on how much air they flow.

I still think the reason the VG30 went twins was cause of the V-configuration of the engine - it just was more practical than running all the pipes into a single - ala Grand National plumbing nightmare!

its pretty cool that you're tyin to ball on a budget here, but i really think its gonna be over-complicated and not make enough results to be justify all that fabrication, especially when you can get the same power goal and spool accomplished with a stock turbo

I figure it'd be similar to a stage2 hybrid, good for roughly 300rwhp before it runs out of steam. Spool is who knows, if just adding the two together gives any idea I'd think it'd be similar to stock.

Turbos ~ $125 shipped to me (thanks jason!!)
Tubing ~ $20 worth, if that much, including hardpipes, downpipes and exhaust.
Plus, I'm going to try and design this around the S4 N/A intake assembly so that I might have a marketable kit.
From my point of view, I'm not out much money, it's only going to require 1 afternoon to fabricate everything and I might be able to make a decent bit of change from it later on. The only things I'm really making that aren't in the norm are the turbo manifold (incredibly easy with a plasma cutter) and the Y pipe for the intake tracts. Unless you can honestly tell me that a true dual exhaust, hard intercooler pipes, an SAFC and a little tuning are all pointless I'll probably keep going.
Ya know, who does make a direct bolt-on 6-port turbo kit? No one.
The project is riddled with reasons to do it, lol.
I appreciate all you guy's input and help on this!
