3 Series E30 LS swap

BMW 3 Series E30 (1982–1994)

A typical 3 Series E30 LS swap runs about $9,000–$13,000 in parts ($5,500 on a budget), and the big decision is where the engine sits: kit mounts set the engine where the kit's headers fit; some builders fabricate to sit it about 1.25 in further back.

Mounts & swap kits

4 options · $275

Why you need it: The mounts set where the engine sits, and that decides oil pan, header and driveline fit. Kit mounts set the engine where the kit's headers fit; some builders fabricate to sit it about 1.25 in further back. The Sikky kit needs an E36 steering rack to clear its headers. More: engine mounts and swap kits.

Oil pan

4 options · $359

Why you need it: The pan has to clear the crossmember, the ground and, on a 4x4, the front differential. The E30 needs a shallow front-sump pan (the Canton 15-276 is 5-5/8 in deep); a GTO front-sump pan needs heavy work to clear the crossmember. More: oil pan guide.

Steering

3 options

Why you need it: The engine and headers have to clear the steering shaft and box, and some swaps need a new shaft or box to make room. The usual fix is the E36 rack (a faster ratio too) plus a flex-disc delete to clear the headers. More: steering shaft and box clearance.

Brakes & booster

2 options

Why you need it: A big cam can leave too little vacuum for the booster, and some swaps leave no room for one. The stock booster hits the driver-side head, so E30 swaps go boosterless or run hydroboost off the power steering. More: vacuum booster or hydroboost?

Transmission adapter & clutch

3 options

Why you need it: An LS needs its own bellhousing or adapter and the right flexplate or flywheel, and an electronic transmission needs a computer to shift it. A stock GM T56 bolts on and its shifter lands in the factory E30 hole, with minor tunnel hammering. More: transmission guide.

Crossmember

2 options

Why you need it: The transmission mount usually moves, and the crossmember sets the driveline angle. A T56 fits the tunnel once the stock crossmember gets a center mount hole drilled and is trimmed to sit flush. More: getting driveline angles right.

Driveshaft

2 options

Why you need it: A different transmission is almost always a different length, so plan on a custom-length driveshaft. Measure in the car, since position varies with mounts; a telescoping one-piece comes out without dropping the rear subframe. More: driveshaft length and angles.

Cooling

3 options

Why you need it: LS water pumps put both hoses on the passenger side and the engine needs a steam line, so the radiator needs LS-style ports or an adapter. An E36 radiator is too thick; one build fit a 1984 Camaro core with a 16 in fan 3/8 in from the pump. More: radiator, fans and steam line.

Harness & computer

7 options · $999–$1,279

Why you need it: The computer and harness have to match the engine's crank signal (24x or 58x) and throttle (cable or drive-by-wire), and the tune has to turn VATS off. A GM PCM ties into about 9 BMW chassis wires; some plug-and-play harnesses only work with the 1998 F-body computer. More: 24x vs 58x, and which harness.
