1987 BMW 635 CSI German spec engine performance upgrades 5 speed no reserve

1987 BMW 6-Series 635CSI

PLEASE don’t just look at the pictures and say this one isn’t worth your time. There is a bit of a story to it, and if you are an enthusiast as I once was, this 6er could be just what you are looking for!

As you can tell, this 635CSI isn’t much to look at. That’s because it ended up becoming an unfinished project. Although it doesn’t look like it, there is a lot of work and money that was put into this car. The black BMW you can see in the pictures was my beloved 635CSI, which I brought with me from Germany in 2001 when I moved to the US because of the military. When I bought this 1986 635CSI in Germany, it was from a single owner and had a little over 60k miles (100000km) on it, and was pretty much in an original condition. All the upgrades went into this car, and it was pretty much perfect with the exception of a good high performance braking system, when in the summer of 2005 someone ran a red light, crashing into the left side of the car, which left it irreparable.

After finally finding another 635CSI for a decent price, I swapped the whole engine and drive train and all of the performance parts from the original one into this white one, and wanted to make it more of a track car, since the body wasn’t in a very pretty condition, so I started to gut out the interior. It then ended up spending most of the next 12 years in my garage not being driven very much. So after that much time, I finally decided that I probably won’t ever have the time and energy to finish this project. I always serviced the engine with premium lubricants and OEM filters. I always serviced the engine with premium lubricants and OEM filters.

Here all the goodies the car has:

·German Spec Engine(approximately 90k miles) factory 218 hp (US version is 182 hp, due to lower engine compression ratio (8:1 vs 10:1) (and milder camshaft 264 vs 272 deg)

·Upgraded Schrick camshaft (280deg duration, 10.4mm valve lift) still streetable

·Upgraded Schrick dual valve springs and titanium retainers in cylinder head

·Replaced factory vane air meter with SPLIT SECOND MAF conversion kit (comes with the fuel controller and a pretty useless A/F gauge, I always used a Wide Band Kit to fine tune)

·Custom programmed Performance chip for Bavarian Auto Sport (BAS) (with custom set redline limiter and programmed for camshaft and engine mods)

·Custom air intake with K&N cone filter

·Big bore throttle body (BMPD) w/port matched intake manifold

·BAS performance headers

·Eisenmann performance exhaust system (no cat)

·SPEC stage 4+ race clutch (I replaced this one after the engine swap, so very few miles on it)

·BAS aluminum flywheel

·BAS short shifter

·MOMO shift knob

·BMPD 3.91:1 Differential Gears ( factory gear ratio for German spec vehicles I believe is 3.07:1, and 3.56:1 (or somewhere around there) for US Spec cars. This was probably done to give the US models some better acceleration due to the weaker engines and added weight)

·Additional Transmission comes with the car (this was the one that came with the white car, and I was told it works just fine)

·Additional set of wheels come with the car

·Sport steering wheel

·Electric Radiator Fan

·External oil cooler (Factory BMW, which came on my original one)

·Eibach Pro kit lowering springs

·Bilstein Sport shocks

·Adjustable camber kit in rear

·BAS Upgraded Spark Plug wires

The not so good:

·Tach doesn’t work, so I put a cheap external one

·Odometer stopped reading speedo still works

·Interior is almost completely gutted, other than the dash board and front two seats

·Small leak from the power steering pump (other than that there are no leaks)

·Tires are worn out on the polished wheels, the other set still has good tires, but the factory size is way too slim for the power of the car

Obviously, I would not recommend anyone to try and make this body whole again; it’s merely there to carry all the good stuff. This chassis would make a great track car, if you put a role cage in, but other than that, I think the best option would be to swap all the parts into a nice 635CSI body that needs a new engine and everything else.

The engine runs solid, no smoke or compression loss of any kind, lots of power and torque. The transmission shifts smooth through all gears. The headers go straight into the sport exhaust system, so there is no catalytic converter, since the German spec vehicles didn’t have regulated cats until I believe 1989. It’s not too loud though, very nice deep sound.

This is a NO RESERVE auction, and the car WILL go to the highest bidder!
