I found a super good deal on a greddy accessory pulley set but it's for sr20det... will they work on rb20det? They look the same

Does anyone know if this setup will be laggy? I'm new to the turbo sizing thing...

t3/t4 compressor trim ar 70 compressor wheel 65.55 /82.00 mm exhaust wheel 45.74 /62.86 mm exhaust trim .48

i'm considering using a .70 A/R compressor with a .48 A/R turbine for my rb20det on a top mount manifold... I read on garretts website that Larger A/R housings are sometimes used to optimize performance of low boost applications and the rb20 from what I understand has poor exhaust flo, so I was thinking the .48 A/R turbine would spool fast and the .70 A/R compressor would make solid power at 15psi. I would appreciate some feedback about this set-up. I'm setting this up for drift, so I'm looking to have power by 3000-3500
