If you don’t care about spool, FP black will do you well. But it has its drawbacks, figment and pressure ratios to name a few, they’re not my favourite if I’m honest. But I would second moving to a rotated setup if you have the cash for that. The EFR’s are nice turbos, just don’t overspin them. I’ve also been really impressed with the G Series. A G25 660 would get you to your power goals and retain very good spool and street manners.
