It's definitely Subiesport quality!
At the very least for their "Reader's Rides" section where they've had much more mundane cars in the past.
I'm thinking possibly even a full-blown article in the magazine myself, even if you have to wait a while until it is fully track proven with more results.
This is a very unique project combining two "classic" (Subiesport's words for the SVX and your Imprezza's the same vintage) Subarus, and your end result is a very impressive and mean looking Imprezza that will surely produce some incredible times. They'll eat this stuff up!
I'd contact Ryan Douthit, the publisher @ 425-458-4949 I've met him a couple of times and he is a big fan of the SVX (but also realizes that too much SVX coverage won't help him in the advertising/circulation department).
That's not his direct line so when someone answers I'd ask for Ryan, and if that doesn't work, ask for someone to talk to about a potential story idea.
Like I said, at the very least you can submit it to their Readers Rides, but I'd shoot higher at first.
