Response to BDA:
John Pels used to sell a kit. I actually managed to find his email (yay for web stocking), and he's trying to see if he can get them made again because he has had a couple of people interested in the past week. If anyone else is interested, let me know and I can get you in contact with him. (You can PM me here or email me at sandersorok@gmail.com)
The Zetec is a great swap, but I am especially interested in the high revving nature of the Yamaha developed head on the 4AGE. I think I want to go for the 20 valve silver top (not black top) because it has a few aspects that I like more than the black top. The black top has a slightly higher compression ratio of 11:1 instead of 10.5:1 due to different piston shape (no not easily interchangeable to the silver top), the black top also has a slightly higher intake cam lift (2mm), and the black top has a wider and quieter cam belt as well as a couple of other features. That all sounds great (so I know you're wondering why I don't want to black top), but the silver top has a spring idler pulley that is more reliable than the hydraulic one found in the black top, and the silver top has stronger rods which are better for high rpm applications. Obviously, these engines overall are really close in terms of specs (I could easily change my mind tomorrow if I find some new info), but the big seller for me is the simplified cam belt tensioner. Since the black top is an interference engine (unlike the silver top), if the hydraulic cam belt tensioner went, it could cause the engine to skip timing and... I think you get the picture. You can change the black top to have the spring idler on the cam belt, but it's a pain.
Thanks for the kind words, and sorry about the long response! (hopefully it wasn't too boring)

Wow, that's great!!! I am still kind of new to the car scene in Brevard County, so I had no idea that there were Europa guys just down the street! I go to Florida Tech, and thank you for the kind words as well.

Hahaha, it's funny you mention the weather. Warm weather was DEFINITELY an important factor for me. (Racing year around yippee)
Thanks so much! I wouldn't miss the opportunity to see an S2 in real life!
