I hope you find the files in this FTP SONiC directory useful, the information is a compilation of my many years of experience with the A body Toyotas. There are many tech notes on performance upgrades, normal service, test results on hardware. See the side panel pictures of the three turbochargers. The FTP site has Dyno tests results from these different turbos tested on the 1982 Supra GTE on the Dynojet 248E.

Please note SONiC is a separate group of Supra owners but is closely associated with the internet Supra group (SOGI). We have been like one happy family for years. I am a subscriber to the SOGI list server mail group. I also and answer many thousands of tech questions every year.

Please feel free to call me with any questions you may have. As SONiC is non-profit I will not able to return the many long distance phone calls I receive, email is the best way to contact me.

The SONiC/RCTS One Lap of America Supra Page

Eight years ago Reg built the Cool and Super Fast 1982 Toyota Supra Turbo GTE, which graces the pages of the January 1995 issue of "Turbo and high-tech Performance magazine". He purchased a wrecked 1990 MA-71 Supra Turbo and elegantly grafted the complete 7M-GTE engine and TCCS system unscathed into the strong light weight 1982 Supra GTS body shell. After pumping up the 7M-GTE turbo engine with plenty of HKS turbo goodies, along with upgrades designed by Regs Engineering company RCTS CANADA the result is  one of the meanest dead reliable street Toyotas ever constructed, not excluding the big bucks 1995 Supra Twin Turbo.
