I am piecing together the parts for my build, and the intake manifold is next. Is the PES intake good for use with a turbo, or is there a better option available, or does it really matter if using a turbo?

Any clue where to find one? 12 Bolt is out and doesn't expect to have them anytime soon.

How much boost?

Get you a Aussie speed intake.. The PES intake is pretty Tall so if you have a issue with the Hood clearance ,That's not going to work out very well.

Look at the 2JZ-GTE manifolds

Just stay with the stock intake and blow harder.

Of course, what was I thinking.
I'd explain the odd shape in the diagram, but then I'd be wrong.
