1994 BMW 525i

So this is one of those cars that I’ve always just loved as a sucker for sedans and the BMW racing legacy, and more importantly something my dad didn’t know how to work on. I bought it for 800$ (usd) with a blown trans from a family friend with 4 rust free doors ?, but the goal for this car is a turbo and bag set up….. if it doesn’t keep eating more transmissions (#3 atm), got a new trans waiting for a bellhousing swap but the last grenade took the drive shaft out with it so I’m stuck until I can afford the new shaft
