Please help me pick turbos Ok guys I need your help. I have ran blower and nitrous but never a turbo car.I got a new 427 ls longblock being built. Lsx block, solid roller cam, brodix bs7 heads flow 400 intake, fuel hoops. I'm shooting for 2k hp on e85. I was thinking about pt 7675s but I don't know if they are enough. Looking for turbo recommendations. I'd like to do this right the first time and save some coin not having to upgrade turbos. Not only im I new to turbos but this will be my first higher hp ls motor, so any help is appreciated greatly. Ken
I would field this question with some big names like Lil John, and also call Precision directly. I'm sure you can get some great recommendations on here, but very few builds on here, hit those numbers. Ronstopable was building a pretty serious truck, but I've lost track of his build, or what it's status is.

I'd get in touch with Jose at Forced Inductions, a pair of Borgs would make the number and be more reliable and less costly than PTE units imo.
Local guy here made about 1,500whp on an LS 388 with twin S476R units just for reference.

76's are great but aren't going to cut it if you want an honest 2000whp. If you want to do it right the first time get Garrett's, anything else is a compromise. GTX4709R Gen 2 80mm would be a good move, essentially 80/84 sizing in other brand speak.

There are several turbos that can do the job. I would second the recommendation to seek out a turbo supplier. Even a tad too small and you'll be pushing a ton of heat making the boost trying to hit 2K.
