E30 Zone

Hi Everyone

Right, Its urgent as I got this donor car but dont have the space to keep it for long.

Project: M50 Powered E30 318i Saloon

Donor car: E34 525i (M reg 1994)
vin (WBAHD52010BJ04371)

Kindly, I would like to know what things I would need or could benefit from this E34 If I am going to change the gearbox as well (I know the m40 original box fits but power matters) so I am fitting the e34 box if it fits

1- Engine (M50)
2- Gearbox
3- if diff is lsd (can it be fitted) ?
4-

Much Appreciated
Please respond promptly if you can

Steering linkage would be beneficial. If you want to use that gearbox then you'll need to source another diff as the E34 one wont fit and your original E30 one won't suit the gear ratios.
