I'm selling ESS supercharged 2006 BMW M5 with Supersprint headers, Supersprint x-pipe, and Supersprint exhaust making over 700hp. It also has snow performance meth injector with boost gauge that will do progressive spray. 132k miles and counting (it's my daily). No check engine, warning light, nothing. It has 7spd SMG transmission. $24,500. It's located in Tucson, AZ.
It's my daily driver. Been reliable for the past 30k+ miles and counting except for starter which was recently changed. ESS supercharger put on about 15k mile ago. When I bought the car, I changed the rod bearings to extra clearanced bearings, new vanos lines, vanos pump refresh with 2010 vanos gear set, new 2010 piston squirters, new motor mounts, vanos solenoids, vanos filter, new tensioners/belts, both new throttle actuators with upgraded gears, both new idle actuators, o2 sensors, all 10 new coils, plugs. All 10 brand new fuel injectors. Did trans flush/fluid, trans hydraulic fluid, and diff fluid/seals as well. All 4 corner pads & rotors changed about 10k mi ago. Michelin 4s tires put on few months ago. Every broken plastic clips and body fasteners were changed to new. I'm probably forgetting more things. I basically read the m5 forums and did every little 'do it while you're in there' upgrades while combing the car over.
ECU is already mapped for a smaller pulley. It's currently at 6psi. I left it at 6psi due to 91octane. Meth is just for safety at this point. Tune was done without the meth injection so you can run it without meth all year. SMG ECU was flashed with euro flash making the shifts way better.
Mileage will go up daily. I just came back from Utah, Colorado, and NM road trip with this car, and it's just time to sell the car after many good miles. Nothing is mechanically wrong with the car. It has expected wears from normal driving but overall in very nice condition throughout. Got front bumper rock paint chips from the road trips. Passenger headlight cover has a scratch. I curved one wheel going through drive-through about a year ago that I can barely see. Had protective film when I got it but I just took it off when I got the car because it was peeling.
Ownership history is an interesting story. It was in an accident by the first or second owner, who damaged the exhaust & subframe cover. The title is clear. The alignment is straight as arrow, and the car will hit over 200mph without issues and without drama. The next owner put Supersprint header on it instead of replacing with a stock one, and it was installed incorrectly. There was a huge exhaust leak which threw codes & made the car run rich. When I got the car, ever since the incorrect header install, it's been through multiple owners who only drove the car few miles before selling it. It ran stupid rich getting about 8 miles per gallon on freeway cruise and made no power. It also reeked of exhaust fume. It was in a miserable condition. I fixed the leak with genuine Supersprint seals from Italy, did compression/leak down test with perfect results (probably result of running car stupid rich for about 10 years), and now makes full power with expected fuel economy.
Feel free to ask if you have any questions. I know this car well. I will not allow test drive unless you pay in full or unless you show up in a car that makes more than 600hp. I will however gladly give any potential buyer a ride. This should NOT be anyone's first or second car. If you're a teenager, don't buy this car. Responsible adults only. Title in hand. Thank you.
The car will come with everything that came off the car when I supercharged it including the manifold, aftermarket intake with sensors, full hardware, etc.
