1987 BMW 531iS With An LS1 Swap Is Up For Grabs

BMW 5-series LS swaps are quite popular, and that’s exactly what we have here with this 1987 531iS, powered by a refreshed LS1 paired with a T56 6-speed manual transmission. The car was recently listed for sale through an auction, but has since been sold for $18,000.

Built by Jake Barkell of Classic Daily, this 531iS features a few goodies and seems well put together. Obviously there is plenty of performance to be had in a nimble car with 400 ponies and a weight of 3,000 pounds, but what’s really neat is that with this powerplant the car is quite fuel efficient. BringATrailer reports that it can get up to 30+ MPG.

With 226K miles on the body, it isn’t exactly perfect. That said, everything is intact, all electrical components function properly, and it even has ice-cold A/C. The car shows its age and usage on the front valence, plastic bumper surrounds, and slightly faded interior. Simply put, it could use a little TLC, but it does have a crack-less dash that was sourced during the rebuild.

Check out the list of modifications below:

  • 228R cam, LS6 intake, 243 LS6 heads, LS7 lifters
  • New pistons, rings, bearings andd all new seals
  • Behr radiator, 2x 10″ puller fans
  • New oil pump, water pump, thermostat, fuel pump and new hoses throughout
  • New belts and pulleys
  • New brake master cylinder, clutch slave cylinder, oil pressure sensor
  • New PCM, custom PCM flash, custom engine wiring harness
  • New rear shock mounts
  • Custom driveshaft
  • Rebuilt rear subframe with 3.25 limited slip differential
  • New Magnaflow catalytic converters, Spintech muffler, 25 Manifolds
  • Bilstein Sport Shocks, H&R springs, ST Sway Bars
  • Custom Motor Mounts

This may not be for those who are purists, but it’ll surely satisfy the winning bidder that sought after a unique cruiser.
