any plans of building another idi in the future?
I highly doubt Dave would. I recently met him for the first time in a few years, and he still drives an older & gasser Mercedes wagon. He's very focused on his fabrication business and isn't interested in another project car. If he has money, he'd rather invest it in tools for his business. He has his own shop with a huge CNC machine, it's pretty cool.
I've been driving a 2006 Jetta TDI DSG for five years now. It's a pretty boring car. Right now I'm building a simple 1996 Golf TDI, but I still miss the damn IDI. I'd love to put a built NA 1.6 (TD longblock with ported head, colt cam, and Giles pump) in a Beetle or a Caddy. I love the linear NA powerband and driving a slow car 'fast' is fun. Can't beat the IDI simplicity and reliability too.
Cheers,
Mark
