Lot 123456789790015: 1987 Porsche 911 Carrera Coupe G50

The G50 and 915 are two very different transmissions, and the G50 in this 1987 Carrera is considered a significant upgrade! Here’s what sets them apart:

915 Transmission (1972-1986)

• Synchromesh: Used Porsche’s own “balk ring” synchronizer system — an older design that relies more on friction and is less compatible with quick shifts
• Reverse gear: Non-synchronized (meaning you need to be fully stopped or match revs carefully)
• Shift feel: Heavier, notchy shifts — especially from a stop — requiring more deliberate effort
• Pattern: Early versions had a “dog-leg” pattern with reverse up by first gear
• Durability: Struggled with increasing engine power over the years

G50 Transmission (1987 onwards)

• Synchromesh: Uses modern Borg-Warner single cone synchronizers — much smoother and more refined
• Reverse gear: Fully synchronized (easier to engage)
• Shift feel: Lighter, more precise shifts with significantly less effort required
• Pattern: Standard H-pattern layout
• Durability: Designed to handle more power and torque — strong enough for Turbos through the 993 generation!

The Bottom Line

Porsche made the switch in 1987 because the 915 just couldn’t keep up with the Carrera 3.2’s power and modern driving expectations. The G50 is worlds better for daily driving with its easier shifts and synchronized reverse, while also being tougher and more reliable.

So this ‘87 Carrera with the G50 is definitely the one to have if you want the classic G-body look with a more modern, usable transmission!
