I remember seeing this pic before, and wondered..
Are the wastegates and actuators still present for each turbo? I couldn't imagine having that kind of $$$ in a motor , going with decent size triple turbos (T3/T04E x3?) and not using an external wastegate - if anything for safety after the fact. But there doesnt appear to be any provisions for an external WG.. speaking of which - WTF is holding up the turbos? The "manifold"? No external stays or gussets? One little weld holding up all that weight? Wanna place bets where the first breaks are on a hard launch?
And its hard for me to tell in the pics, but are the flanges 1/4 or 3/8? In any case the difference in price would have been neglibile to use a 1/2 flange, and eliminate any possibility of warping and add a more solid base for welding. Doesn't really matter since its probably 304 stainless anyways so it'll break/warp no matter what :P 321 always!
I don't want to sound like I'm bagging, but having made most of the mistakes you possibly can fabricating a turbo system, It pains me to see things this early on that are so contrary to the way I learned, especially with such a beautiful setup. Anyone know where this car/motor is? AUS maybe? Being three years ago I would think it'd be done by now and I'd love to see the finished product.

The turbos are supported by brackets and it's using 3 external w/g (not shown). Internal w/g are welded shut and bypassed. IIRC, these are GT25.
It's going into an FC (I wished it was for my car)
.
Is it just me or does anyone else think the turbos won't spool until 6K rpm? With turbos that big being powered by only 1 rotor's exhaust I can't imagine it'll have any low end power...

GT25's are pretty damn small. With the right exhaust housing, and proper porting, I bet it will spool pretty damn fast.

I dunno but the top pic looks so familiar..Is it an Aussie car? I remember when I worked at Racing Beat there are some serious rotaries built by those guys, and have been for years. I think it was Mazspeed that had some of the nicest. I forget, been a while since I got to flip through a FF&R mag.
FC huh? dayum.... cant wait to see the progress on that bad boy

Here's one more recent pix he sent me...this time with the camera's date correctly set.
