Just my opinion, but I say save your money and spend it on a better project. Unless you're doing most of the swap yourself, it sounds fairly expensive, and very time and labor intensive.

The P70K + potential costs on the engine swap would make for a good downpayment on another (newer and hopefully faster!) car with a more robust platform to start out with and wider aftermarket support.

Again, just my personal opinion. If you do plan to push through with the project, best of luck to you. And let us know how it turns out!
