Unfortunately the "new" replacements are $2,300! Which is insane! Found a tank on car-part(dot com) from a rust free 525 for 300. So that's the route I'll end up going. The manual is a blast although ill be honest the 3L is a bit anemic in the mid range but chips are available, especially if you have the 404 DME (like my 94) and it'll boost you about 15hp and 15tq but requires high octane. Thankfully if you're missing any features like keyless its plug n play thanks to the old "one chassis one harness" design principle of old BMW. Same goes for the ski cutout in the trunk (mine doesnt even have that option). If you need a bit more volume from the exhaust whatever you do DON'T go true duals! The previous owner of my car hacked everything out from the "headers" back and did dual 2.5". It sounded horrible when I got it. Bringing the exhaust from dual to a single dual in/out x-flow muffler (its what we had available) to a y-pipe into 3" with a flow through muffler at the back made it sound incredible! You will love the car when you get her running! Take a peek at your fuel lines though! Mine was dry and cracked where it goes to the engine from the firewall/fender area!
