3rdgen I'm thinking appropriate sized turbine wheel for the compressor you are running but smallest A/R housing for it to get max response. Then two gates one to limit boost based on intake pressure the other gate referenced to exhaust back pressure to keep exhaust pressure at or below intake pressure. The exhaust pressure reference line would likely need to be a hard line and long enough to coil to let it flex and help disapate heat. I dont know if you could disapate enough heat to prevent damage to the extra gate. Seems like it could work but dont know if its ever been tried.
For what I'm building I dont want too much boost off the line and will just size my turbine(s) to favor mid thru top end.
