Here's a list of Websites that I recommend.
The best resource for information about turbocharging your
old or new Mazda Miata. Whether you're putting together a DIY kit or buying a complete package, this site caters
to both audiences.
The one and only website for the miata owner
and enthusiast. Forums, classifieds, how-tos and more.
Flyin' Miata Turbo Kits
Excellent vendor who wrote the book on turbocharging
the Mazda Miata. If you want the best turbo kit that money can buy, check out there site. They've got LSx swap kits too!
Do it yourself water / alcohol injection
Little plug for my site that will show you how to build a high quality,
reasonably priced water / alcohol injection system. A MUST for all turbo cars, period.
