Help Choosing Turbo

i need some help with my setup, im going to be running a foged 347 (stock crank) at around 9.0:1 compression. my goal is for around 850-900 rwhp and still be streetable, this will be a truck manifold kit also. im looking at a borg s475, or a pt88, would this be achievable on the s475? any other good choices without droping alot of cash on a turbo?

it depends on how fast u want to get full boost? i would choose a devided turbo with a lower A/R so it will spool fast as hell. mp76 or the new mp80 thats comming out

You will need at least a 80mm to 88mm for the level of power and speed you are wanting.

streetable as in power off the line? or just driving around town. I'd go for a T76 with the ability to up the boost when needed

im runnin a s475 on my lt1 and its gone 6.20@112 2nd time out on pump gas. so i think with good flowing heads and a good spec'ed cam a s475 will get you there but itd be maxed out! it would prolly be pretty laggy on the street tho!
