Plazmaman designed and manufactured CNC Aluminium Gearbox Adaptor, to adapt Mazda's 13B engine, to Toyota's near bullet proof R154 Supra/Soarer 5 speed gearbox. It isn't hard to extract huge power out of turbocharged rotary engine, which compromises the reliability of the OEM upgrades available from Mazda. Fortunately, Toyota had over-engineered the R154 Supra 5 speed which will take just about anything you can throw at it!
The adaptor kit has been designed to be used with a Series 4, or Series 5 bellhousing ONLY. The adaptor kit comes with all the necessary Hi Tensile fasteners for fitment.
