How much boost you plan on running?

a4ls2goat

the more boost you run the less wastegate you need.

cubes + turbine size + minimum boost \ placement = wastegate size

but yes, simple single turbo fbody style build single 44 and ship it

salemech

no more than 17psi

salemech

what do you mean placement.

so what i understood is
346+76mm+10psi \ placement
is that right?

If you want to try and regulate it very low then the bigger the better. I run a tial 38mm with 20psi, 370 CI 900 whp.

But short answer is just get a 44mm and call it a day. Wont really matter all that much if its a run of the mill setup and you dont plan to be below 6psi.

For me, big enough so that it doesn't creep. I hate that.
