This 1989 BMW 325i is a modified example that is powered by an S52 inline-six mated to a 5-speed manual ZF transmission from an e36 M3. It was purchased by the previous owner in California as a roller with a blown motor. Receipts detail an approximate $12k build from Ottowerks of San Francisco, with an additional $10k in modifications and maintenance from the seller’s five years with the car. Additional modifications include e36 suspension and brake components, a 3.25 LSD, e30 coilovers, a custom exhaust, and more detailed below. It is now being offered for sale with extensive records, an extra set of wheels fitted with track tires, some spare parts, and a clean Pennsylvania title in the seller’s name.

The seller states that the car has seen about 15 days of track time at HPDE’s with various car clubs. A set of ASA AR1 17×8.5” wheels fitted with 235/40 Nitto NT05 track tires is included in the sale.

Body panels appear straight and paintwork displays a nice shine. A scrape on the right rear corner and some damage to the bumper is evident and the seller notes some surface rust on the roof and driver’s c-pillar. A Ground Control 5-lug conversion kit was installed. Style 32 rims show some curb damage and light marks and are wrapped in Michelin Pilot Super Sport rubber that measure 205/45/17 in front and 245/40/17 in the rear. The rear wheels are said to rub under hard compression.

Interior modifications include a roll cage, Sparco Evo II racing seats, an alcantara-wrapped Mtech 2 steering wheel, Condor tall weighted shift knob, and an aftermarket head unit. A crack in the factory dash is shown in detail in the gallery. The odometer displays 222k chassis miles.

Approximately 130k miles were said to be on the S52 inline-six when it was installed by the previous owner. About 25k additional miles were added by the prior owner, and 35k miles were added by the seller. The 5-speed manual ZF transmission comes from an e36 M3 and is fitted with a UUC short shift kit, routing power through a 3.25 limited slip differential. The head was cleaned, valves resurfaced, and a leaking head gasket was replaced along with valve cover gaskets and VANOS gaskets under 250 miles ago by Bimmerworks of West Chester, Pennsylvania. Valve seals and springs were also replaced. Bottom end work was completed by the prior owner, including bearings and one piston rod. The seller added an automated larger spal fan and Stuart water pump.

Suspension upgrades include front suspension, front brakes, lollipop control arm bushings, and steering rack components from an e36 M3. The rear subframe and brakes are from an e36 318ti, with e30 coilovers and camber plates. A custom 2.25” exhaust with a Remus muffler is fitted. Large sway bars and an aggressive alignment are reported to bring a stiff ride, but the car is said to feel light with power that is well-suited for track-use. Spare parts include extra tail lights, brake pads and rotors, oil filters, cracked fog lights, and the extra set of wheels.
