I picked up a set of Garrett 60-1 .63AR turbos with stage 5 housings. Cold inlet is 4" outlet 2.5. T3 flange with 2.5 exhaust. I currently have a stock GM 350, 4 bolt, 290 hp, 8:1 compression engine. I only want 4-5lbs of boost for now with THIS motor. Are these turbos too big for my needs? I want room to grow also. My max RPM range will be around 5300. The car has 3:25 gears with a 2400 stall and a turbo 350 tranny.

Are these good turbos?

Oh this is a TWIN turbo build.

Thanks guys.
