The titles listed below are ones that we have identified but unfortunately have either limited information or incomplete sets of cover images. We continue to search for these images so that we may publish a complete set.
- B Scene (??? - 2008). This title was published by Buckaroo Communications and John Dianna. Content was aimed specifically at the tuner car show scene and related events including drifting, solo racing and drag racing. We are uncertain as to the start date, but the title likely ended in 2008 when all the other Buckaroo titles ceased production.
- Drifting. Published by the same folks who brought you Import Racer, this is likely the first publication dedicated to the sport of drifting. The editor was Edward Loh. Coverage included activities in both the U.S. and Japan.
- Honda Sports Tuning. Little is known about this title. It may have been a limited series.
- Hot Rod Honda. This was published by the good folks who brought us Super Street. It was likely intended to be competitive response to Honda Tuning from McMullen-Argus.
- Modified Luxury & Exotics (2004 to 2008). This is another title started by Rob Laidlaw and his VerticalScope enterprise. Content was focused on performance upgrades to higher-end luxury and exotic cars.
- Siphon (2006 to 2008?). A spin-off from Import Tuner, content was focused on tuners who loved the micro-compact segment.
- Street Power. This publication was issued by the editors at Super Street. We believe in started in 1996; the end date is unknown at this time.
- Street Racer. This title was published six times per year by Drive! Media. It started in the late 1990s; we are uncertain as to the end date.
- Traction. Little is known of this title, but it was started by Source Interlink Media. Online, many blogs referred to it as a "lame tuner" magazine.
- Turbo & Hi-Tech Performance (1985 - 2009). This title was started by Kip Kington in June, 1985. It originally had content that was 50-50 between domestic and import tuners. But when Michael Ferrara joined in 1994, content shifted almost exclusively to import vehicles. Mr. Kington sold the title to Primedia in 1999, and in 2009 it was folded into Modified Magazine.
