Another Long Diff/Tranny story
Diff ratio and tranny to sort out.
Tranny:
Was looking at a 700r4 or 200r4. Mainly 700r4 race manual reverse shift. So that would be
p
R
1
2
3
D
Right? Want it as a race manual so it holds that gear like a manual does.
But when the numbers coming in:
3.06 first x either 3.9 or 4.10 for diff = not good ( looking at 255x45x18 tyres)
My modern 10 plate v8 (ls2) car is 3.02 x 3.45 ( diff ) 255x40x19.
Would the 200r4 be better ,as x4:10 rear,
I mainly shift at around 3k ...so
3k 1st around 35kmh
2nd then down to 1800rpm
For the speeds around my area ( kph) i try to have the tacho around 2400, so in power range.
Engine will be a ls3 480hp creat motor with a 1800 converter. ( trying to find a h[/torque graph for that motor.
Does the 2004r need mods? other than new shaft and x member.

it was just the way the internet site called it. Some places say this or that for the same thing.
After alot of looking, decided, the 200r4 with a 3.9 diff. 255x45x18.
Just didn't like that 3.06 1st of the 700r4.
Manual auto is a must. Bto tranny's look ok, any other places can recommend.
