This 1989 BMW 325is was acquired by the seller four years ago and has since been fitted with a 3.2-liter S54 inline-six from a Z4 M Coupe and a six-speed manual gearbox from an E46 M3. The build was completed in November 2017 by Rhom Innovations in Portland, Oregon, and also included a custom 3″ exhaust system, M3 control arm bushings, a Z3 steering rack, UUC Motorwerks brakes, Recaro seats, OZ racing wheels, and more. This E30 is offered with service records, a clean Carfax report, and a clean Oregon title in the seller’s name.

The body is finished in black and features side skirts along with an iS front lip and splitter, Euro grilles and “smiley” ellipsoid headlights, and an M-Tech 1 rear spoiler. The trunk lid has reportedly been repainted, while the roof and replacement front valance are wrapped in gloss black vinyl. The seller notes that rear bumper is a different shade than the rest of the paint and points out a dent in the rear valance.

Factory wheels are replaced with white 16″ OZ Racing alloys wrapped in BFGoodrich g-Force Sport COMP-2 tires. The seller notes all four wheel bearings were recently replaced. Suspension, steering, and brake modifications include the following:

Refurbished Z3 steering rack

Garagistic reinforced powder coated adjustable rear subframe and trailing arms

M3 offset front control arm bushings

Ground Control street camber plates

Bilstein HD shocks and H&R springs

UUC adjustable front and rear sway bars

UUC Motorsports big brake kit with Carbotech race pads

The cabin features heated black leather Recaro sport seats with “M Rain” center inserts along with matching shifter and handbrake boots. Custom door panel inserts have been added, as has Motorsport-themed contrast stitching throughout. Controls include a Renown steering wheel and a Rogue Engineering short shifter with a Condor Speed Shop weighted knob. A functional “M Sport” button has been added to the center console that changes the tuning of the car, and a European-market analog clock with Motorsport branding has replaced the stock onboard computer. The seller notes one-touch window switches were also fitted, along with intermittent settings for the windshield wipers from E30 Innovative Goods.

The custom refurbished gauge cluster features gray-faced instruments including a 160-mph speedometer, 9k rpm tachometer, and an odometer showing just under 73k miles, with total chassis mileage unknown. A Panasonic head unit has replaced the factory stereo. The seller notes the air conditioner is inoperable and the heater fan is in need of replacement.

The 3.2L S54 inline-six was reportedly sourced from a Z4M Coupe with 70k miles and installed by Rhom Innovations in Portland, Oregon on a reinforced subframe from Arc Asylum. Additional modifications include a custom-tuned E46 M3 ECU, an oil cooler, a CSF Racing radiator and SPAL fan, Turner motorsports power pulley kit, a fuel cell with a Bosch pump, a modified Arc Asylum S54 oil pan, and a K&N air intake, and a Garagistic strut tower brace. A cold start video can be seen here.

Custom exhaust headers feed 3″ piping with a MagnaFlow muffler. Shifting is handled by a six-speed manual gearbox from an E46 M3 with a new clutch, and a Garagistic secondary support has been installed ahead of the 3.46 limited-slip differential.

The Carfax report shows previous registration in Colorado and Oregon as well as listing a mileage discrepancy from the current odometer reading. Driving videos can be seen below.
