Just to clarify this is not the huge 04/05 style replica STI scoop made for bugeye this is an oem wrx scoop cut up to fit the bugeye hood. I've seen a few members do this in a few different ways so I decided to post up my attempt.
First I made a paper template of the opening in the bugeye hood and Traced it onto the bottom of the 04/05 Wrx scoop with the template even with the front so I was only cutting off the back which was about this much...
Here's the result..
Next I shaveed ALL the slotted tabs off the front
Then I cut out a sheetmetal piece using the same template and welded threaded studs on the bottom that line up with the holes in the hood to mount it. Then cut out the center and mounted it to the scoop using the 2 screw holes on each side
Then I epoxied and jb welded around the entire perimeter. This is end result.. Note this is where you can see the problem you will run into as the scoop is narrower than the hood opening..
There was also this in the corner...
After that I fiberglassed the edges and sanded Leaving me this..
I just applied a thin layer of bondo to all fiberglassed areas, once that's done I'll sand it again and post finished pics
