Twin-turbo, forged bottom end, and a crank hub that wants attention before you add power. The F80 and F82 live on our lifts. We know which bolts are stretch, which gaskets weep, and which tunes actually hold together on Chicago pump gas.
OEM-style capture or a pinned hub, timed properly, with the timing verified afterward. If the motor's already open for bearings, do them together and save the labor.
Inspect, measure, replace. WPC or coated bearings on request. We document the old shells so you can see what you were driving on.
Ethanol content sensor, bigger pumps where needed, port injection for the cars that are going to lean on it. Tuned on MHD or Bootmod3, logged on real roads.
Downpipes, intercooler, charge pipes, intake, hybrid turbos up to big single setups. We'll tell you which parts move the needle and which just cost money.
Oil filter housing, VANOS, cooling, driveline, brakes. It's still a BMW. We still fix those.

Send what the car is, what it's doing, and what you want out of it. We'll come back with questions, not a price. Once we know what we're looking at, you get a real quote, and it doesn't move unless the car surprises us. Then you get photos while it's apart.
We'll ask the annoying questions, then give you a real number.
