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.
