Your going to end up with a severe hot spot right where that triangle insert is, you've 'dog legged' the flow pretty hard, You might want to consider using a heavier wall at that point. Also the the way the Turbo is oriented to hang off that flange, ( assumed by the flange angle), is going to put allot of stress on the flange welds.. brace the turbo to minimise that loading.
^^What he said. That triangle piece is going to get HOT, hope its thick. Your wastegate runner should be smack in the middle between your runners. Putting it on the rear only defeats the purpose of making your main runners equal and will make your rotors see different back pressures from one another. Will it still work? Yes, but its not optimal, and since your MAKING it, why not do it right.

when i did all my 12a turbo setups i always had the best response and power with a much longer runner manifold. i started with manifolds like what you have there and it just didn't work as well as i had hoped. the 12a doesn't flow as much so you need to make the best of it. that will work tho

It's the way frosty wanted it, almost all the mani i make are long to build up boost pressure. But I'm pretty sure it will work fine same kinda of power give or take. Hope you like it frosty, will post pics soon of the waste gate runner.
A month is the least amount of time. I am going to be running a holley blue 110 gph pump with rising rate regulater from rotary shack. Im just looking to start with 7 psi and see how it goes. This is a pure project car so Im sure in time Ill be running 10 pounds or more.

Again if you're running a holley blue for your fuel pump on any blow through setup it will not work. Even witha boost refence FPR the holley doesn't produce enough pressure to over come the boost pre throttle blades as boost starts to build at part throttle. Especially with how fast it's going to build with a little t3.
I never heard this, Ive been planning to use a holley blue this whole time. I will have to look into it more extensivly before I buy thanks!

Frosty Im sorry to say but the holey blue pump is not going to work well if at all!!! The pump doesn't push out enough fuel for the turbo demand. And since your running turbo you need more fuel and some. Red holley pump or something higher by holley will work fine, or aeromotive. I highly do not encourage you not to run the walbro pumps they burn out quickly, work to hard, and to fast causing the fuel pump motors to fail, which in turn will blow the motor. If you need help hit someone up here on the the thread or just hit me up if you have any other questions.
