you might get by with a 38mm but I would go 44mm to be safe

Single 60 on the merge or twin 38's (one on each head pipe). I am using the twin 38 setup on my s475

I have a Trick kit with the log manifold and my 38mm wastegate is mount in the crossover pipe. It can limit boost down to the 7lb wastegate spring and probably a lot lower if i put a lighter spring in it. I'm running a Magnum 76/68.

I don't mean to be a dick but did he say 60? I cant help but to laugh. 60 really

38 will get it done, 44 will give you, 60 come on now.

I ran a Tial 38mm and then a JGS 40mmm on my setup. Both controlled boost down to the spring rate just fine.

That should be perfect.

I use a JGS 50mm with my TC76 and 5.3L, works like a champ. With the 2-port hookup method and my eBoost street I can get a boost range of 4-14psi on the light spring.
