That is a very origional, "cool" idea! I really like fresh new ideas that use some inginuity like yours did. Nice job!
The only thing I am concerned about is if this will offer enough increase in airflow that the Flexalite fans will be ok. Flexalite fans can barely keep a 1j cool in 70deg weather, let alone climbing a big hill in the summer. Are you going to put big vents in the hood? I would like to see it from the front. Another thing I notice is the "hot air intake" with the turbo heat shield removed. I think putting that heat shield back on would be a good idea, especially with a twin turbo setup like the 1j has.
