For modified toyotas ZOOM is one of the best and gives a more technical overview as opposed to the Bling that other magazines promote. I suggest you buy a few and work out which one caters for your style the most. Personally I like ZOOM and High Performance Imports. Autosalon occasionally does good technical features but the knowledge of the writers is not as good as ZOOM. Hot 4s and Rotaries, Fast Fours, etc may also suit you, but most of they time they just talk crap.
