so yours are a bit larger. i'd be happy if they were good to 600 a piece, they appear to be 62mm turbos.

I can't find the maps for them but I'd guess they'd be a nice fit for your motor. I don't have much experience with motors smaller than 5.7 but I'd think they'd work just fine for you.

they seem to flow a max of 84lb/min.

Those turbos are pretty small, and will only make about 400-450hp each. The turbine wheel is a fair size, but the compressor will run out of steam very quickly. They might be rated for about 84lb/min combined, but certainly not each.
