88mm is a lot of compressor for only a 650hp goal. A 78/75 would get there with way easier packaging and spool time. An s475 would be a smaller package as well and still have a large enough backside to make power up top. A stock stroke 360 will feel lazy on the street with a 88 in my opinion.
Even a 78/75 is lazy on 360 inches. That’s a 8-900hp turbo. Turbos are like camshafts everyone wants a bigger one and is pissed when it disappoints them. An s475 (a real one) is a 6-750hp turbo and probably a good choice for a street, mild 360
