Project FD RX7 Restomod: Part 30 – Finishing the V-Mount with a CSF Intercooler and Vibrant Performance

  • Billy Johnson

Turbo Compressor fabThe inner diameter of the HD clamp was slightly larger than the outlet of the turbo, so we had to clean up this ‘step’ to improve airflow.

Borg Warner EFR Compressor FabAfter a bit of grinding, everything was nice and smooth.

Borg Warner EFR Compressor Housings Vapor BlastedThe Borg Warner EFR compressor housings were taken to get vapor blasted (left), which gave the housings a nice, bright, matte finish.

    That V-mount design and the way the air intake tucks in perfectly to the side is so cool. I still can’t wait to see the end product! Hopefully Mike can get some vids of it out of you for the YT channel.
