Turbo sizing for 5.3 Hey guys I'm new here. In the process of building an 81 Camaro. Already filled gutted except for a kirkey, 12pt cage, 9" Ford, forged 5.3 with prc heads, studs, still deciding between a th400 or powerglide since I have both laying in the garage. Will be a fiberglass nose on the car and limited street driving.
Anyways I found a good deal on twin eBay gt3582r turbos with 6462 wheels and stainless t3 vband housing .82AR, or should I just go to the s480 1.32
Goal is to run a high 9 and still be half decent on the street.
running Holley Terminator x and a flex fuel setup, flowtech 1 3/4 turbo headers with the flanges chopped and 2.25 v bands on them. I'm afraid the t3 .82 housing will be to small and I'll have backpressure issues

They will both work pretty well. I think the s480 has more power potential, but the twins will probably be more responsive.
I wouldnt worry about the housing too much, you can search for agp twin turbo kits on 5th gen camaros. They are making 1000whp through them on 376-416 cubic inch motors.

Either of the two setups will get you the goal of a high 9 second pass. A smaller set of twins would be a lot more fun for street driving over the s480. I see no reason for a powerglide for your goal. Th400 is cheap and easy and hard to beat all around

I have these eBay gt35s on my 5.3

i had full boost by 3800 which isn’t to bad but my buddies comp 76/75 is a really good setup for the 5.3 he can prob make same as me if not alittle more on pump gas. Not sure his spool yet cause not on dyno but it feels like comes on faster than my twins.
