1988 BMW M5 M30 Turbo Swap

s-l1600
Typically the legendary S38B35 is an engine that gets swapped into other BMWs, now out of them, but today we’re playing opposite day with this No-Effs-Given E28 M5. A little while back it received a turbocharged M30 transplant which is a pretty common setup for E28s – just usually done on more pedestrian models than the extremely rare M. A unique aspect to this auction is that the S38 comes with it, so you have the opportunity to ride the turbo monster as long as you please while retaining the prospect of putting the numbers-matching engine back in eventually. Even so, any hopes of originality are long gone after they spray coated the floor rooting out some rust, replaced the wheel and shift knob with anachronistic wooden parts, and spray painted the homebrew center console to accommodate auxiliary gauges. The one thing that I actually do think is original, contrary to the seller’s claim, is the black interior. With all seats, door cards, and interior trim in black, and miles instead of km, I think this may well be one of the 31 US M5s with black interiors (more than 2 the seller thinks they made, but still an extreme rarity).

This M5 has been hacked and sprayed to the point that it will forever be valued more like an E28 rather than the second-rarest M car. It looks pretty darn good from the outside, albeit modified with later wheels and yellow lenses, and the S38 alone could recoup a serious chunk of the purchase price. It’s already into 5-digits with a long time left on the auction and looks like this basket case M5 with its heart in a box will still pull decent money.
