If you're going to use that thin of a wall I would atleast use 321SS;

you could probably make some sort of "mount" for the turbo. or jus do some bracing. I am either gonna run a T-61 or a GT-42 (clones, not actual garretss, im too poor) I am gonna use that same bend (well two of them) and figure out a way to make a mount or support as i was told you should never rely on the manifold to hold the weight of a turbo.

I built a 42R manifold for my 3 rotor. The turbo weighs over 40lbs. I wouldn't even think about supporting it with the manifold runners. I suspended mine from the water pump housing using a chrome alloy bracket that looks kind of like a suspension A-arm.

here is what i did for my 42














and my manifold is made out of sched 10 SS.... which is much thicker than thin wall 16 ga....... 16 ga un supported would just fall over once operating i would think

the only way i would do a manifold in which the runners support full turbo weight is if the runners were of sched 40 pipe

this is on an a rew engine in my fc... and i could stand on the brace before any of the manifold was done

the 42 is a 45lb turbo.... which is considerable
