Fluid MotorUnion

This shop lives up to the hype and reputation. Brought in my car for something that isn’t ordinary. Installing hood pins and drilling into my new carbon hood. The process did take a little longer than anticipated. The team was very communicative and made sure everything was dialed in while also taking care not to damage the hood. I appreciate all the hard work and attention to detail. I’ll be back for other services down the road.

The staff at FMU were great. They were able to get me in right away which worked out well for me. I only took my SQ5 in for an oil change for the initial visit. They took care of that along with a detailed inspection of my car's other systems. I will be going back and I will also be bringing in my wife's car when maintenance is due. Great job all!

Would recommend for your high-end, rare or custom built vehicle. Working with the shop crew and especially OJ will convince you of their talent, knowledge and expertise. Thanks, FMU. I am again enjoying my Twin turbo TA and the exhaust build video.

$12k, 14 months, main problems not fixed, several thousand dollars in additional damage caused, and no desire to take accountability for their mistakes was my experience. I've tried to resolve my issue with Fluid Motorunion before posting this, but they ignore my calls and emails as soon as they found out I wasn't happy with their work. I took my 98 M3 Turbo to Fluid Motorunion after a problematic custom turbo build at another shop. The car was stalling occasionally and the check engine light was coming on for a cylinder misfire every 100 - 200 miles. They did a complete inspection and were able to fix a few of the easier items they discovered along the way, like replacing a control arm and bushing, but I received the car back with the same problems 14 months and $12k later. Here are the details: Fluid Motorunion sighted I had a head gasket leak. They sold me a stage 3 cylinder head that they said belonged to one of their customers who had bought it for a project, but never used it. I said no, but after waiting 6 months for parts on back order from VAC I agreed and asked for the original receipts. Donny told me they had no receipts, but I agreed anyway with the promise they'd send me lots of pictures. I asked for the pictures several times over the next few months and was finally told, oops, we already put the engine back together. I was upset to say the least, but the worst is yet to come. When I picked up the car, the rear seat was not installed, the fog light was dragging on the ground and the engine oil catch can filter was smashed, like someone had leaned on it. I also experienced the same issues of stalling and the check engine light coming on. At this point I felt Fluid Motorunion was not going to be able to resolve my issues and I was wasting my time and money there. I did a lot of research and was lucky to find CES Motorsports in Monroe, NC. Here's a quote from the owner, John at CES about what he found when he opened up my motor: "We pulled the motor and broke it down and have news… I have pics attached. The cylinder head is built, but not quite ideally. The valves are upgraded, and upgraded retainers, but when the cams were installed, they must have stripped a couple of the stud holes that hold the cam trays and bridges in place, and they ended up tapping the head and installing bigger and also different threaded studs to try and fix their mistake. These bigger studs also required them to bore out the cam bridge holes to a larger size to fit the bigger studs, and they were also tapped crooked. To make matters worse, the cam journals in some areas are heavily scored with pretty deep scratches in them, which would suggest the motor was never primed properly when it was cranked, and damaged them before oil could get up to the cams to lubricate them. Or there was excessive debris in the motor when it was built and broken in." So YES, the head Fluid Motorunion sold me for $2400, $6,416 installed, was leaking, and more importantly not useable because of it's condition. Maybe the head was already a mess from the customer and they didn't see it, or maybe they did the damage themselves. I don't know. HERE'S THE BEST PART OF THIS STROY. I emailed the owner Marilyn with this information and received no reply. When I called a couple of weeks later she was very apologetic about everything and asked me to give her a couple of days so she could investigate the matter and told me that they had insurance for this sort of thing. It’s been 2.5 months - I've sent multiple emails and left voice mails, but received no response. Now when I call Fluid Motorunion, the phone goes straight to voicemail. Maybe they can do good bolt on mods or custom exhausts, but I would never take my car there again solely because they won't even discuss their mistakes.

I’m from out of state, I found out about FMU through Alex from Legit Street Cars. I happened to be in Naperville for a family trip and decided to give them a visit to discuss building a custom exhaust for a BMW M6 E64, I wanted the high pitch sound that the V10 engine deserves. When I first met O.J. and his team they were super attentive and listened to what I wanted, and they set the goal to make it happen regardless of what had to be done. They built it on a E63 chasis they had in house. When I received the exhaust it was a work of art, unfortunately it didn’t fit, but as soon as I communicated the issue O.J. and Marylin brainstormed with me and we went through many possible options. I know that modifying a car sometimes can take unexpected turns and it can be frustrating but I looked at the bright side, I decided to send the car, I decided to add sport cats to decrease the smell of gas so I can cruise with the family, and ultimately they were so apologetic and open to help me out going so far out of their way to satisfy me. I assumed the responsibility for costs that were my own fault, I realized my aftermarket headers had a different connection to the OEM exhaust which didn’t pair with the new custom exhaust, I also knew my E64 convertible had underbody braces that the E63 coupe doesn’t have and that played a role when maximizing the tube diameter it just had a bit of conflict with the chasis brace support. They redid the job and improved on their work of art. But to really put a cherry on top, FMU really went above and beyond, the day I flew to pick up the car to road trip it back home they were getting it ready with fresh fluid change and found a small oil leak from the oil cooler (common issue) and they managed fixed it before I got there. O.J, Marylin, Cody, the FMU crew they are truly standup guys. I decided to make lemonade out of lemons and after the fitment issue I cruised back home and made a stop through The Tail of the Dragon.
