Turbo manifold and stand alone ecu Q's

Alright, so I am just starting my 07 Aveo Sedan LT project and I'm going with forced induction @ 7 psi. Just wondering what turbo manifolds are out there that will work for the e-tec II, if any; or is custom fabing the way to go. Would a cast manifold work better than a tube style for long term reliability? Just finished a turbo build on a 94 civic a month or so ago and had lots of problems with the tube style manifolds cracking at the flange that bolts to the block. And what is the best/most reliable stand alone ecu to use. AEM stand alone was used on civic build, but I'm not too sure what would be best since there is almost no pnp options for the Aveo :cool:. Not concerned about the money/time needed, just want it done right the first time. Learned the hard way on my previous build about the cheap and easy things that should never be done ;). Any advice is appreciated.

I would run megasquirt, or do an actual turbo engine swap.
