We recently completed HAMS' 930 and it had a Precision turbo, 6262 iirc. It was a source of friendly disagreement between Chris and myself because we've seen too many Precision turbos that were junk, compressor wheels contacting the housing, etc. He'd used them on his other cars, no issues. It has worked well on his build (3.45L EFI ITB), but not significantly better IMO than a GT35R such that I would spec one for my own 930.

Same for the BorgWarner EFR we just did. They spec'ed out their 35R-killer, it cost a lot more and was harder to fit, and didn't significantly out-perform our usual go-to setup.

We've now done 620whp on a 3.4L running e85, but if you've got a bigger engine or really hot build and need a bit more compressor wheel, Garrett has a new Gen-2 version with a larger compressor wheel inducer that will flow a bit more.
