Rb20 Turbo Question

[swdriftsociety]

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

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