Why? It should make gt35r power with gt35r spool and costs more than a gt35r. The compressor maps between them are almost the same and the hotside would be the same. The only possible benefit is the smaller diameter of the compressor wheel which although it may spin up very slightly faster if you look at the compressor map it has to spin faster to flow the same air anyway. I know that's all arm chair engineering I'm hoping someone has a back to back comparison to show why it's worth it.
Edit Actually I believe a 35r has more power potential than a gtx3576 and will spool the same if not sooner.
