Complete No 18 head (lifters, cam, injectors, etc) and updated vac pump for $250, now I have two heads and a parts car. lol My garage is looking like a swap meet.
Tons of factory BMW turbo stuff, got the entire setup for about $225 on a 1/2 price day at PickNPull... manifold, turbo, tubing, oil filter housing w/ cooler, wastegate, intercooler, Motronic, etc. The turbo fetched over $200 alone on Evilbay.
KKK turbocharger for the SD, $30. NO shaft play at all.
560 rear foot rests that match my maroon interior for the SDL... PRICELESS

But seriously, those came with a big pile of other bits I picked up such as switches, a few GP relays, some Beckers, and other misc bits for $60.
I'm out so much I hit deals constantly. The guys at the yards know me by name and divulge inside info to me on when they're expecting cars. It's great.
