S5 6 port turbo

Now i have a 91 S5 engine sitting in a Rx7 in my driveway.. i was going to get it driveable and build up my 12a for turbo in my '82.. but i have decided to use the S5 for the FB...

Now i will be using a 60-1 .70 compressor/ .84 turbine... it will either be a larger SP or bridgie/half bridge.. i was wondering which rotors i should transplant.. I think the 9.7:1 might be a little high for a turbo, ive heard of good success using S4 NA blocks (9.4:1) and turbos so transplanting s4 rotors could be a possibility .. or should I just get a set of T2 rotors? Any input would be greatly appreciated..
