1983 BMW 528e Maintenance and Modifications History

General Condition
I am the original owner of this BMW. This vehicle has the original paint and interior, showing minimal wear and careful care and maintenance of all surfaces. Zymol products have been used exclusively, to wax and treat painted, vinyl and leather surfaces. Gummi Pfledge is used on all weatherstrip seals. Electrical connections are maintained using CAIG Labs products, since new. Normal operating maintenance involving oil changes, fluid changes, etc., is not addressed here, other than to indicate that RedLine and Castrol synthetic lubrication products are used well before recommended change intervals. The vehicle has never been damaged or exposed to severe weather conditions and the vehicle has been covered when parked inside and outside of its garage. It is normally parked in an insulated and heated/air conditioned garage. The engine, drivetrain and suspension have been carefully maintained, with receipts for all work and parts since I took delivery of this BMW, new, from the dealer. No major maintenance has ever been required on any items, beyond normal wear replacements and BMW service campaigns to address issues detected during E28 model production.
The car has won Judges Choice, First Place and Second Place in the past three years at the annual BMWCCA National Capital Chapter Deutsche Marque Concours d’ Elegance event. The car is well known by a number of my BMW peers, who consider the car exceptional, given the quality of its original components condition, the extensive and documented preventive maintenance performed over the years and type of the modifications made to it.
Summary of Modifications to Vehicle (items not originally installed on the vehicle as delivered)
• E32 7-series front brakes, (E34 530i rear brakes installed/removed) and all brake hoses replaced with stainless steel hoses.
• AC Schnitzer full leather 350mm steering wheel. BMW M-Tec 1 385mm recovered and E36 M3 BMW M-Tec II 365mm steering wheel modified and fitted with a MOMO coarse spline hub is also used.
• Hella Euro 7-inch & 5-3/4-inch headlights, grilles and associated high capacity wiring and switching system.
• Bilstein Heavy Duty shocks and ST 22mm and RD 16mm adjustable front and rear anti-sway bars.
• Later model radiator fan shroud installed. This October 1982 build did not have one.
• BMW E39 style 29 16x7 ET20 wheels with aluminum hubcentric adapter rings.
• 1987 325e DME/ECU type “027” with D’Sylva E.A.T. 528e performance chip. (+20 hp, +500 rpm redline)
• 1988 528e tachometer face with 5200 rpm redline. (replaced original 4750 rpm redline face)
• Wiechers-Sport front strut support brace, with associated modifications to engine component locations (Idle Control Valve, Radiator Expansion Tank and Throttle and Cruise Control cables) for brace installation. Original rubber hose used to reposition the Idle Control Valve has been replaced with an aluminum tube, since the rubber hose was found to be collapsing under high vacuum and creating an erratic idle problem. See the website.
• Custom polished and detailed valve cover and associated brackets.
• Taillight modifications to unused lamp sockets for improved stoplight visibility of vehicle from rear.
• Install illuminated window and sunroof control switches (7).
• E32 750i upper Thrust arm bushings and stainless steel heat shield for right Thrust arm bushing.
• 1988 3.46 Limited Slip Differential replaced factory 2.93 Limited Slip Differential. An excellent ratio and combined with the E.A.T. chip, overal performance has improved significantly, without impact to the fuel efficiency I have previously monitored for over three years!
• Pearl beige leather shift boot from Creative Options.
