you cant beat a t4 at 2.2 bar 7800 rpm
my old yb was just polished ports standard size with a pair of 14s and held 2.2 bar without surge from 5300 rpm onwards. 408 hp atw.
my egts at the downpipe were up to 1000c 160 mph + on a defi gauge which i am told makes the manifold around 1200 c
engine and turbo never battered an eyelid though for 5k hard miles.
they are definateley a seriously robust turbo, dont worry about the lag thats what gearboxes are for

I haven't chosen anything yet.
What are the bad points? I think a bit of lag would be alot of fun with RWD?

a t4 is a 500/550hp turbo; greys are a 450hp injector

quite the opposite mate; if you want a t4, then you need to be aiming for over 500hp with a nice 42psi boost spike

i'm pretty sure they do an internally gated gt3071r, so even easier
you'll need a live map tho IMO to get the best out of it
