tech info main

I intend to place here some informative links and scanned articles from various magazines. During years I acquired collection of auto magazines from different countries, my favourites are Sport Compact Car and Turbo from USA. There are some other interesting magazines from States, like Drag Sport, but I don't see it on the book store shelves. They are dominated by Super Street - like mags written for boys under 16. No offence intended for younger guys, I meant people looking mostly on outside appearance of the car. I think I am getting old, but it is really boring to flip through 200 glossy pages and find only pictures of body kitted BPU cars and numerous ads of chrome wheels, air filters, stereos, etc. I started buying V8 scene magazines and found them interesting even for sport compact car enthusiast. I wish we had magazines similar to "Engine Masters" pushrod guys enjoy. Another fantastic magazine is Option, but how many people read Japanese?
