Wally, nice job!
I hope those 25.5s will be OK, because I also bought them for my project. I guess, I'm waiting for the update about how they changed Your Bug, meaning driving feeling!
Regarding Your performance, those numbers looks serious. I believe most of us trust Your opinion on turbocharged Type 4 engine subject (I do, because I don't know anybody else who made engine "from schratch" with totaly simple parts, plus modern tehnology like FI and Turbo to get serious numbers). I'm wondering only one thing:
Considering Your today's knowledge, experience and abilities, how much Your engine costs? Roughly. Is it 3000 euros, 5000 euros, or what? I really trust You on this one, because I was thinking about STI (sorry people) because it costs me 2500 euros, has 300 HP and 350+ Nm.
Thank You!
