Proper WG placement should always be a priority. In this application, the fagtastic "tear drop" works about 100x better than the solution you've come up with. Big frame turbo or small frame turbo, WG location like that is far from optimal and leaves a weak point in the system. Will it fail at the weak point? Maybe, maybe not. Still would suck in 2017 Steve has his kid fire up the car and gets to the dyno and the damn manifold won't hold boost. Personally, I'd offer the band aid fix in this circumstance of a 44mm WG instead of the 38mm.
As for the drag manifold argument. #1's plugs look different than 2,3,4 but not so much different that you'd say all of the exhaust is pulled out of #1. So you are both right and wrong.

If you don't think there is a pressure bottle neck at the turbine which causes steady state flow originating from cyls 2-4 that eventually makes it's way up cyl 1 runner, you are uninformed. If you don't think there is a pulsed flow that travels down each runner at the beginning of each exhaust valve event, pings off the turbine, and travels back wherever the ---- it pleases without being the least bit impeded by differential (pressure) flow, you are uninformed.
How the ---- do you think reversion happens if exhaust doesn't flow back up runners?

if you havn't designed and built manifolds please stfu

I've tuned several hundred more one-off manifolds than you've made, and the concepts involved are elementary. When a wastegate exit is placed in such a manner that boost control is easy vs one where it is not, and all other factors are kept the same, it's real easy to pinpoint the wastegate exit angle as the dog, especially when the exhaust has to come to a complete stop and to some degree reverse direction.
We are discussing the merely obvious here, what you do is a lot of hard work with a little precision measurement and skill thrown in but you aren't a ------- rocket scientist so don't ever treat me like I don't know what I'm talking about again.

I've got more pics from tonight, which really only detail getting all the glass back in. Other than that, me and Austin (G2Turbo Terror) put a honda myth to rest.

Colin (Snabfxu...) never ended up showing for the wiring. He had ME homework or some ----, so me and G2Turbo Terror ended up drinking, putting in glass, and making videos (shown above).
