Honestly, it's gonna depend on what turbine wheel they have, and what style of turbine housing and the A/R. If you compare this turbo to say a 50 trim that has a 54mm compressor wheel, they are kinda small. The 50 trim has a small Stage 3 T31 turbine wheel and is rated to support 450 fwhp maxed out. I'm guessing these 52mm turbos might have either a TO4 69 trim turbine wheel or a small shaft P trim turbine wheel. If so and they have a T4 Tangential v-band style turbine housings, they will make a little bit more power. But in all honesty, if this is indeed what they have in them, they are too small for a 274+ CI Stage II.
If they have T4 Tan housings and either one of those turbine wheels, they should be able to make close to 500-550 hp each. Now, if they have T4 On center style turbine housings, the hp capability is going to be slightly lower. Somewhere in the 450-475hp each range. On Center style T4 turbine housings are a no no. Most of the time the only reason people run On Center style housings is because it allows for easier fabrication of the downpipes and positioning of the turbos in tight engine bays. (Very common on TT Mustangs)
If you must run a T4 housing, always try to no matter what run a Tangential T4 V-band style turbine housing. There could be as much as 100hp being left on the table on larger sized turbos.
If you have the ability to take inducer and exducer measurements of the turbine wheel, I can better help narrow down the power ratings.
Here is a pic showing how to measure inducer and exducer.
