Hi Ken, and Welcome To The Madness known as Speedster ownership! If the pics are of the Speedster you're buying it's a great looking car. With 2650 cc's I'm guessing that it has a type 4 engine- you're looking for a good aircooled mechanic (someone who still works on VW stuff and knows dual carburetors). Don't think that a Porsche dealership will service what you have; they may not even want to look at a replica, and if they do prices will be outrageous, and most of the mechanics there won't have a clue. Wanting to make your car more "Porsche like" is up to you, but know that a lot of P owners won't think much of a replica (it doesn't have a P vin #) so don't expect to be welcomed into fold.
Enjoy what you have for what it is- a super cool car to drive, and remember we're all here to help with whatever comes up. Al
PS- I'm in Vancouver
