BMWotD — 1988 M3 with S50B32 Swap

I don’t ordinarily gravitate toward e30s, but this one is quite special, and I would certainly make an exception. If money were no object.

An e30 M3 in Hennarot, with a European S50B32 motor in place of the original 4-cylinder. Don’t get me wrong, a car like this with the original 4-cylinder is no slouch, with 192 hp behind a ~2,800 car. But that S50 engine puts out in the neighborhood of 320 hp, which would make this car a rocket. The purists might will most definitely freak out about the departure from the original configuration, but even the most diehard purist would have a tough time finding fault with the quality of this swap.

88′ Hennarot M3 with a S50B32 Euro motor.
191,0xx miles on the chassis, approx 79k miles on the motor/transmission.

I purchased this car in the spring of 2013 from a gentleman in CA who had done most of the mechanical work on the car, and really made it into the wonderful driving car that it currently is. From my understanding the car was largely stock when he bought it several years before my ownership, from that point he focused on maintenance that the car needed. I have a binder containing some of the documentation from the previous owner.

The motor swap is obviously the biggest change over stock. I’ve been told by two separate and independent shops, that the swap was very well done. The engine is very strong, and runs extremely well, I had a compression/leak down done on the car before my purchase and all cylinders checked out perfectly. In fact, the company that sold him the motor wrote ‘superb engine’ on the valve cover while they were testing it. I’d estimate that engine has been in the car for about 6000 miles. When I took delivery of the car I drove it home 1300 miles, it was a great drive, and the car didn’t miss a beat. About half of the miles that I’ve put on the car since I’ve owned it where driving it home, I just don’t get a chance to drive it much. I never had any intention of selling this car this quickly, but I’ve started a E28/LS1 project, and have an E30 touring project lined up behind that. I’m in no hurry to sell it, but I need it needs to be driven and an enjoyed more than I am able to do.

There isn’t much to nit pick on this car, you can get in and drive it across the country, or to work everyday. It has major and expensive upgrades that arguably make it a better car. Better in the sense that it has a power train that is more reliable than the S14, it creates more power, brakes harder, and turns faster.

As you can see from the pictures the paint is in fantastic condition for a 25+ year old car. If you have never seen hennarot in person, it’s a gorgeous color, and also quite rare, I believe only about 300 M3’s were produced in this color. I am happy to answer any questions serious buyers have, I’ve tried to be as thorough and forthright with the condition as possible.

The following photos were taken by Brian Lewis of SpeedFreak Detailing after he did a complete paint correction to the car in November. The car has primarily been stored away since.
