Hi all,
I was wondering if anyone has or knows where a G50/50 may be available for sale?
I'm looking to do a DeLorean LS3 430 HP/428 lb-ft conversion. Although the Renault UN1 gearbox can be strengthened with upgraded parts which include a single input shaft and a Quaife LSD it apparently can take up to around 500HP and 500lb-ft of torque BUT not if the clutch is dumped and other similar abuse is put on it. Although my car will be 90%+ driven on the road I would like to take it to the odd racetrack and drag strip to surprise other enthusiasts as to what a DeLorean can do. I don't want to therefore be wondering if in none road use scenarios as to what it will take for the UN1 to break.
To recap, a DeLorean is rear engined like a 911 so most other gearboxes won't work unless you want 5/6 reverse gears and one forward gear.
Current UN1 369 5 speed gearbox is stock: 3.36:1, 2.06:1, 1.38:1, 1.06:1, 0.82:1
final drive 3:44:1
The strengthening upgrade I 'was' looking to do would also make 1st and 2nd much closer and 5th would be changed to a .70 ratio to drop my revs on the motorway to help with economy and a quieter cockpit.
I've found two Porsche gearbox contenders due to the 5th gear being nearer to around 0.7 that was possible with the upgraded UN1. Also the 6 speed is longer and heavier plus I've learnt that 1st and 2nd syncros are stronger on the 5 speeds.
Space is a real issue with this project as just a 'few extra inches' in new transmission length combined with the extra length of the LS3 engine make it tighter
The two options are
G50/50
G50/52 (by changing the bell housing to that of the G50/50
