Btw N/A, thanks for the advice. I'm not intending to put anything stupid on my car like a T88 or anything. I was actually wondering whether you could get something with similar performance to a twin setup (2530's or t517z's), just something nice and simple. I don't want something that reaches full boost at 5K, and is a pig to drive, and I don't want to strain the poor old RB26 too much, so if there's no single turbo solution I won't do it.
The last thing I want to do is end up going forgies, rods etc etc....
