From E30 Zone Wiki
The E32 is the second generation of BMW's 7-series, and replaced the E23 in 1986. It remained in production for ten years before being replaced by the E38 in 1995. Sharing extensive styling cues as well as engines, it it is a contemporary model of the E30 and E34.
Considered to be the pinnacle of contemporary BMW engineering before the accountants stepped in, the E32 represented all that was great about luxury autobahn cruisers. With engines starting at 3 litres the E32 never pretended to be anything other than a beast, with the most behemoth variant being the 750iL - an extended-wheelbase saloon powered by a 5.0 litre V12 engine.
Despite the opulence and power available, the E32 has already found a home in scrapyards. The cost of using and maintaining such a juggernaut has proved too much for the wallets of second-hand owners, with rust and infuriatingly complicated electronics being the main cause for their absence on today's roads.
These are the parts can be bolted directly to the E30 with little or no modification. They are considered an upgrade for either strength, performance or cost reasons. Anything not on this list is either directly incompatible or requires significant fabrication to fit.
Main article: Engine Swaps
NOTE: While the V8 M60 engines are by no means a drop-in swap, there are enough documented examples of them being fitted to E30s for them to be considered a viable donor engine.
E32 calipers have also been fitted with 312mm Audi TT discs.
