There are two kinds of BMW shops in Connecticut.
The first kind services BMWs. Oil changes, brake jobs, diagnostic work. They treat your car the same way a dealership does, as a vehicle that needs maintenance, not as a machine with potential that nobody has unlocked yet.
The second kind builds BMWs. They understand the difference between what a B58 does from the factory and what a B58 is actually capable of. They know what a properly tuned N55 feels like compared to a stock one. They have built S55 M3s that embarrass supercars at a fraction of the cost and they have the footage to prove it.
Tysautoworks Performance in Meriden, CT is the second kind.
We are a family owned BMW performance specialist located at 47 Billard Street in Meriden, Connecticut. We serve BMW enthusiasts from every corner of the state who are done with the factory limitations and ready to build something that reflects what they actually want from their car. This is what we do, this is what we love, and this is why Connecticut BMW owners keep coming back.
Performance Upgrades We Build at Tysautoworks Performance
Turbo Upgrades
The factory turbocharger on every BMW that leaves the plant is a compromise between performance and the requirements of emissions certification, warranty coverage, and broad market appeal. It is not the turbo your engine deserves.
At Tysautoworks Performance we install drop-in turbo upgrades for Connecticut BMW owners who want significantly more power without converting to a full big turbo setup, and we build complete big turbo packages for those who want to push their car to its absolute limit. We have built B58 M340is, N55 335is, S55 M3s, and N54 builds across every power level. When you tell us your goal, we tell you exactly what it takes to get there.
Aftermarket Exhaust Systems
The factory exhaust on a BMW is designed to make the car as quiet and inoffensive as possible. That is the wrong goal for a performance enthusiast.
We install catback exhaust systems, valvetronic exhaust systems, downpipe upgrades, and complete exhaust builds for Connecticut BMW owners who want their car to sound the way the engine actually deserves. Akrapovic, Eisenmann, FI Exhaust, Meisterschaft and more. Quiet when you want it, absolutely outrageous when you do not.
Intake Upgrades and Turbo Inlets
Every turbocharged BMW engine breathes better with an aftermarket intake. Better airflow, colder air, and the induction noise that BMW worked so hard to suppress suddenly filling the cabin every time you get on the throttle. We install cold air intakes, front mount intakes, high flow intakes and MAD turbo inlets for every major BMW platform in our Meriden shop.
Charge Pipe Upgrades
The factory plastic charge pipe carries every pound of boost your turbo produces. On a modified BMW running elevated boost, it is the weakest link in the entire system. We install aluminum charge pipe upgrades for Connecticut BMW owners running any performance modification as a foundational part of every build we put together.
Intercooler Upgrades
More boost means more heat. More heat means less power and more risk. An upgraded intercooler keeps intake air temperatures under control so your tune delivers its full potential on every pull. Direct fit upgrades, front mount intercooler systems, complete intercooler packages for every B58, N55, S55 and N54 build we put together in Connecticut.
Engine Swaps
The most committed statement a BMW enthusiast can make. Swapping a turbocharged N54 or N55 into an E90 chassis, dropping an S55 into a lighter platform, building a N54 single turbo that nobody sees coming. These are projects that live at the intersection of mechanical skill and genuine vision, and they are some of the most rewarding work we do at Tysautoworks Performance.
Performance Transmission Builds
More power needs a transmission that can survive it. We build upgraded ZF 8-speed automatic transmissions with reinforced clutch packs for high torque applications, rebuild Getrag manual transmissions for performance street and track use, and have experience with performance clutch packages for every manual transmission BMW platform.
Why Connecticut BMW Owners Choose Tysautoworks Performance
We are BMW only. Not BMW and Mercedes. Not BMW and Audi. BMW. Every tool we own, every technique we have developed, every hour of experience our team has accumulated is specific to the brand. When your car comes into our Meriden shop you are dealing with specialists, not generalists.
We document everything. Connecticut BMW owners who want to see the quality of our work before committing to a build can watch it on our YouTube channel. Real cars. Real builds. Real results. Nothing staged. If you want to see what an N54 big single turbo build looks like from start to finish, we have filmed it. If you want to see a complete S55 oil cooler replacement or a B58 exhaust install, it is all there.
We are honest about what your build needs. We do not sell Connecticut BMW owners upgrades they do not need to hit their goals. We do not recommend components that are not right for the build. We tell you what your car needs, what it costs, and what it will do when it is done. No upsells. No surprises.
We are a family business. Tysautoworks Performance was built by a family that loves BMW the same way our customers do. That passion is in every build we do and every car we send back out onto Connecticut roads. Your car is not a ticket number in our system. It is a project we take personally.
Connecticut BMW Builds We Are Known For
Connecticut BMW enthusiasts who have been following Tysautoworks Performance know the builds. The G80 M3 that sounds completely illegal after the catless downpipe install. The G30 540i that makes every 335i owner reconsider their life choices after the Active Autowerke downpipe. The F80 M3 oil cooler rescue that saved an engine its owner did not know was in danger. The E90 starter replacement that beat a shop quote by thousands of dollars.
These are not cherry-picked highlights. This is the regular work at our Meriden shop. Connecticut BMW owners who bring their cars to Tysautoworks Performance leave with cars that are better than when they arrived, every time, without exception.
