1991 BMW 318iS M62B44 V8 Swap 6 Speed OBDII
Description
Up for sale is a car that took me two years to build. A 1991 318is with a M62B44 (V8 from an E39 1997 540i) mated to a 6 speed manual Getrag 420G transmission (also out of a 1997 540i). The car itself took months to find, specifically looking for a accident free late model IS coupe. The motor came from a non-accident donor car that was hand picked for this project. I had the entire drivetrain and wiring so this swap was done the correct way. I was not planning on selling this car, but I stumbled upon an LS1 E30 M3 project, which is the only car I would rather have than this, so unfortunately it is for sale.
DRIVETRAIN
The motor and transmission have 120k on the clock. Compression is high and consistent across the board and the transmission shifts perfectly. A Z3 short shifter has been added and makes the shifting very crisp. The motor is cooled by a Mishimoto Z3M radiator which is the best radiator you can buy for this setup with the help of an electric fan. The motor is ran by an OEM ecu (dme) tuned by DUDMD, a tuning shop out of Maryland. The tune adds an extra 15 hp and 15 tq, raises the redline, no top speed, and deletes the need for EWS. All the power goes back to the 2.93 medium case LSD, which closely matches the OEM gearing of the 540i.
I used the garagistic motor and transmission mounts along with OEM rubber motor mounts for a comfortable ride. The radiator support is removable (10 bolts) so the engine and transmission can be easily removed or worked on if you want to modify. The driveshaft is the E39 front professionally welded and balanced onto the E30 rear. The exhaust is a custom build that uses modified E39 headers and cats and is custom from there. All of the fluids are fresh (engine oil, transmission, power steering, brake fluid, diff fluid) and I used expensive synthetic stuff all the way through. The car does have a small oil leak that I believe to be the valve cover gasket. I have put 150 miles on it since completed and the dipstick still shows full so it is a slow leak.
Handling
Stance coilover suspension (this is a street/track setup do not confuse with the stance scene) with front RX7 big break kit, which is a 4 piston and larger rotor compared to the single piston OEM setup. This is not a no booster swap which are known for weak braking and a bad pedal feel, it has the remote booster relocated to the front of the engine bay. This car still has power steering. The 17" wheels have brand new 235 width sticky tires.
Interior
All of the OEM gauges are working correctly. Speedometer, tachometer, oil pressure, coolant temp, etc. It has a very clean black sports interior along with an mtech steering wheel, and 6 speed E39 shift knob to match the transmission. Blower motor does not work on high.
Exterior
Overall good shape for its age. It does have some peeling clear coat on front bumper, fenders and fenders. It does have the typical rust spot on the rear below the battery box and a small amount of surface rust on the bottom of the passenger side door. I was planning on buying some replacement fenders off a car being parted out, but didn't get around to it. This is a sunroof car and it does have the 'smiley' headlights. Just stated the negative for full disclosure, but again, for it's age this car is in great shape and straight as an arrow.
Overview
Thank you for looking. As this is a unique build I welcome any and all questions about the car. Do not let this car scare you. I purposely built this car to be easy to work on. The body components are all E30 and the drivetrain is all E39. Everything for this car can be bought over the counter other than the driveshaft, which A isn't something that typically breaks and B can be purchased online. I spent a lot of time building this car the right way because I never thought I would be selling it.
You will not find another car like this out there. There are very few M60/M62 swapped E30s. This is the perfect combo - M62 (larger motor), non TU (no unnecessary parts that break), late model (better looking), coupe (lighter), 6 speed (better than 5 speed), right color (not champagne), OBDII working (only one i know of on the country that has this). If I had to guess I would say I have well over 1000 hours into this build over the past 2 years.
Many extra parts included - airbag steering wheel, OEM suspension, OEM brakes, OEM wheels, many M62 parts, etc.
