If you decide on CR190 there is a 56mm hybrid that is available from xman turbos that, from the little information we have on the forums, is a better solution (solves boost creep if I'm not mistaken).
Mac, you have custom oil lines for those turbos you listed to use on the EA288? The oil return is located very high up on the block, just an inch below the exhaust manifold rather than closer to the oil pan on previous CRs. A custom hard line with bellow was needed in my case. The oil feed as well has to kick out 90deg to clear the balance shaft.
CR190 hybrid would be easiest solution. Stock oil lines and downpipe work, only thing needed would be the different TIP and compressor connections from the GTD.
2260 would probably be a blast though. The kit from Darkside will have the proper items needed (they're currently test fitting on a GTD over there). The only thing I would question in that kit would be the silicone TIP as the brake booster is on the other side of the engine bay in a RHD car, so they have tons of clearance whereas it's tighter with our LHD vehicles.
Anything larger than CR190 will likely need a CP3 upgrade as well for more fuel up top.
