U mean T4 turbo right? Cuz the T3 is a smaller, faster spooling turbo than the 18G. Trying to get 400 WHP out of D series isnt really very streetable to begin with, no matter what turbo u choose. Personally I think that the 18G would be a bit too small. I would think the 20G, or the T4 would be the way to get there.... but who knows, cuz I dont see anyone in this forum spending all that money building up a lonely ol D series.
