I have an RD28T + 5 speed fitted in a classic car.
The gearing is all wrong though, 3.9 diff(there is no other diff ratio available) means it is revving at 2600rpm at 100 kph.
I want it 2000rpm at 100kph
Am running 205/70 14" tyres.
Is there a 6 speed that will bolt on to the RD28, apparently the RD28 is the same as the RB range of engines.
The engine i have is ex Nissan Patrol but gearbox is Laurel or Skyline 1989ish.
