1. what are the ratios on the 320i box and 325i touring box? is it as strong?
2. does the M20 box fit a M30?
3. will the Z3 quickshift bits fit the M30 box if different to the M20?
reason being, i have a clattery 325i box with a VERY bad shift. i'm looking to possibly have the low mileage 320i box from my wifes E30 if we break it (it's got aircon, abs, leather, 11 button obc, etc etc etc!!!) and fit the quickshift bits i've bought. at a later date i want to change to either a M30 or something large and 24v and a recon box would be worth hanging on to.
cheers!
