6 Speed Swap on the WRX STI (12x32)

:

Subaru 5 speed Gearboxes have a reputation of being weak, a few launches and they are often exploded into a thousand pieces. A 6 speed gearbox out of a newer STI is an excellent upgrade and in this episode with the help of our mate Benny (aka Mechanical Stig) we swap in an entire driveline into Marty's 1999 2 Door WRX STI.
