there was no other way to do.
Engine bay is just air and letting theme open meant just see air and light coming from the front, giant air intakes when model will be finished.The lower PE guide for vents is also a must to locate theme at the proper measure,and with a proper angle inside the resin of bonnet. The side vents over wheel arches are open now.....cause under it there is a big thick resin part covering the fw wheels.
Those vents are absolutely the hardest part at all of this model,and being placed one by one in position I am just satisfied with this result
In resin models some stuff must be compromises...u know

Had really no way to open bonnet and build up the compete Nissan engine

LOL
