I can also build a header like intake with a small collector plenum into throttle body and get the runners within 2" of equal but can be 18-20 inches long or mimic the stock Insight 3cyl intake design.
Or I can cut my hood (and move my battery) which I really don't want to do
Im afraid of loosing all my bottom end as it is an automatic. Im hoping that with the tuning ability and a great exhaust system, I can make up for the intake manifold compromise. Im not looking at trying to win any races but do want the car to be as efficient as possible.
Im not for asking anything other than ideas and opinions on this.
If I build a short runner intake, can I build Tq with a long intake tube before throttle?

I think your best bet is to build a tubular intake that mimics the stock tubing length. I believe you can do this by having the tubes stick forward and then turn down, into a plenum located below/to the side of the alternator. Throttle body would be on the driver's side of that plenum with air intake/filter near the transmission. From your picture of the engine compartment, I think you will have enough room.
At part throttle operation, the throttle plate should disrupt any pressure waves, so the tubing before the throttle doesn't really help with tuning pressure waves at the valves.
