rb30 gearbox conversion

[Bax]

My old stocko would get around 120, but give and take a fair bit because speedo's vary and so do rev's apparently.

 

[VL Berlina 5speed]

yeah probably not as quick on the initial takeoff but you'd get 70km/hr out of 1st.

yah i can get the 70ks out of my first gear, so if i was to change the diff ratio to say 3.9 or 4.11 that would make the car run equivelant to a stock vl 5spd with 3.45 gears ?
