Mazda Rx7 FC to FD Bell Housing Adapter Plate

Green Brothers billet FC to FD bell housing adapter is CNC machined in-house from aircraft grade aluminium 

This allows FC (S4/5) 13B turbo bell housing to bolt up to FD (S6/7/8) and Rx8 5 speed transmissions, enabling the use of a later model Rx7 or Rx8 gearbox in an earlier application 

No input shaft shortening required, no other modifications required - this is a bolt on conversion 

Double lip oil seal and high tensile bolts are included 

• FC (and earlier) bell housing - 141mm height
• FD & Rx8 5 speed bell housing - 156mm height 
• Height differences = 15mm
• Adapter thickness = 15mm
