We are nearing completion of this project and will be officially listing it soon. I haven’t tallied the final bills yet, but I’m guessing our asking price will be in the high $30s / low $40s depending on what original parts the buyer wants. In the meantime here are the details.

Summary

 interior photo

This is one of thirty US market 1988 (E28) M5s with the desirable black interior. It has been converted to a nearly European spec M5 with many other highly desirable upgrades. I am selling it on consignment for a good friend and a fellow longtime BMW CCA member and instructor. It is an exceptionally clean E28 M5, despite its high mileage. It is so clean that it won 3rd in Second Generation Class at the 2013 BMW CCA Oktoberfest Concours in Monterey, California. It is also proof of my theory that BMWs are like airplanes in that proper care and stewardship are much more important than strictly age and mileage. Nearly all mechanical components have been refreshed, yet it just imperfect enough to enjoy on the street, track, or autocross—as every BMW M car should be—without the guilt you might have with an extremely low mileage example. It is also highly competitive, a class and overall winner at the autocross events listed above—a rare feat for an E28 M5.

Like most M5s of this vintage, the original engine developed the timing chain housing leaks that every S38 eventually gets and we suspected the valve seals also needed attention. But, it just so happened we knew of a 96,000-mile E24 M6 S38B35 engine. We acquired it and sent it to old school BMW engine builder Mark Hutto to properly sort and build into the S38 that every US-spec M5 should have come with. This included inspecting the bottom end, resealing all leak areas, replacing the timing chain components, and rebuilding the head. In the process we added an S38B36 intake cam and had it custom degreed to work with the stock exhaust cam. The engine is breathing through a Millar MAF conversion and 100mm intake tuned by a Miller War chip and exhaling through European E28 M5 exhaust headers—the single best performance enhancement you can make to an S38. We had the headers ceramic coated and mated to a custom test pipe. A VSR high-flow catalytic convertor will be included with the sale for emissions compliance. The original cats are also available for extra. Remaining housekeeping items included re-brushing the alternator, adding new oil cooler lines, and tidying up wires and hoses to look factory correct. The original engine is also available for extra.

The end result of our build is a fire-breathing monster, but one that retains the elegant understated class of the iconic E28 M5. This is the monster that you can bring home to meet your mother. When I drove it to the exhaust shop with un-muffled European headers it sounded exactly like a classic DTM racecar. I may have taken the long route just to enjoy it more! I’ve heard a lot of intoxicating BMW exhaust notes, but none were close to this. The Stebro exhaust retains this sound, but makes it refined enough for daily driving. The enhancements allow the S38 to breath at high RPMs in a way the stock motor never could. The noticeable effect is that this M5 keeps pulling exponentially as the revs build where a stock M5’s power band would start to flatten. It’s all blissfully mechanical—that old school M car recipe of a high revving, high compression, and normally aspirated inline engine unfettered by the forced induction or highly computerized engine management.

We would like to find an owner who will continue this M5’s excellent stewardship pedigree and enjoy it for years to come.
