Same as a 19T but with a way better flowing exhaust side.
Didn't the 3000gt came with twin TD04 9Bs?
There's two types greddy one and std one of the 3000gt
The later one is a bit more laggy and should take 1.5 ish bar boost
And full boost around 4000 rpm on 5e pending on engine and map
The other is a very nice turbo which I used almost same spec check my old garage
2 bar no prob
I'm running a greedy td05 14b on emb @ 1.4 atm full boost around 4k
