1. Superior Engines
Website: http://www.superiorenginescolorado.com/
Address: 6900 Lakewood Place, Lakewood
Contact: (303) 233-2342 | [email protected]
Hours:
- Monday – Friday: 8:00 AM – 5:00 PM
- Saturday: By appointment only
Superior Engines avoids mass production. Every unit is carefully assembled by technicians with decades of experience, guaranteeing that your engine is in good hands.
The team can handle complex tasks like block thread repair and head surfacing right on the premises. On top of that, they use dealership-level tools to program modern vehicle computers.
I recently spoke with a fleet manager who swears by their in-house machine shop. He noted that it drastically cut down his company’s vehicle downtime.
The company even backs its precision work with a massive seven-year, unlimited-mileage warranty, which brings customers instant peace of mind.
One downside is their narrow focus on heavy powertrains, so you’ll need a different shop for minor cosmetic repairs. Also, their Saturday hours are strictly by appointment. This makes weekend drop-offs a bit difficult for the average commuter.
Customer Reviews:
Fantastic service
I was needing a rebuild and had looked up a few places and my gut said bring it out to these guys and I’m glad I did! My engine looks great I’m putting the dressing back on now. Fantastic service, they set me up with break in oil, gaskets and they were great to talk with!
Thanks again i’ll post again when it’s done.

The shop has been very thorough
Scott has been absolutely terrific to work with.
He brought my 300 back from the dead, and he made it incredibly affordable. I understand from reading other reviews that certain people have had different experiences, but I can tell you that Scott is absolutely the guy for Hemi rebuilds here in Denver. It’s a small shop and they handle a Lot of business – so my advice is – Be Patient with the entire staff. I’ve had my rebuild back for almost a year and the shop has been very thorough and easy to work the entire time.
Highly recommend this shop.

2. Western Engine Supply
Website: http://www.westernenginesupply.com/
Address: 750 E 71st Ave

Hours: Monday – Friday: 8:00 AM – 5:00 PM
Navigating the logistics of a major engine overhaul can easily turn into a scheduling headache. Western Engine Supply eliminates that stress by being the only shop in Colorado that offers both precision machining and full installation under one roof.
They’ve maintained a strong local presence since 1989, known for rebuilding every part to meet strict manufacturer standards.
We like that instead of relying on simple visual checks, the team uses an advanced test stand to verify oil flow and timing before the motor is installed. This extra layer of quality control prevents any nasty surprises when you turn the key.
However, their service hours are strictly limited to weekdays, which is tough if you work a standard job.
Plus, they lack official accreditation from the Better Business Bureau. This might worry customers who want formal third-party vetting before spending thousands of dollars.
Customer Reviews:
The engine is a stunner!
I had Western Engines rebuild my 351 Cleveland and the engine is a stunner! They had recommendations along the way, sent pictures, and even let me visit during the 4 month process.
I can’t wait to get it put back into my 1973 Mustang! Thanks to Mike and the gang for the great communication and help

I had an excellent experience
I had an excellent experience. I didn’t have a press and needed some new pistons swapped over for my engine rebuild. Quick and timely. Competitively priced. There could have been a little better communication/service, but don’t let this deter you from using their services.

3. Automotive Engineering
Website: http://automotiveengineering.net/
Address: 6541 Washington St, Unit T
Contact: (303) 487-5708
Hours:
- Monday – Friday: 8:00 AM – 5:00 PM
- Saturday: 9:00 AM – 2:00 PM
Commercial drivers know that finding a reliable garage for heavy-duty rigs is much harder than finding one for a standard car. Automotive Engineering fills this gap with their rare ability to work on both light cars and large diesel engines.
By operating their own dedicated machine shop, they can handle high-precision work such as block boring without relying on outside contractors. Their main goal is to restore every engine to exact factory specifications so it performs perfectly on long hauls.
When I had to coordinate a massive diesel overhaul last year, their deep knowledge of specialized tools made the process very smooth.
However, their focus on major rebuilds means they’re not the cheapest choice for basic electrical repairs. Also, while the shop has a great reputation, it’s not officially accredited by the Better Business Bureau.
Customer Reviews:
My expectations have been wildly exceeded
I brought my engine to Mike for a rebuild. We had a brief conversation; I went with his recommendations. He balanced the rotating assembly and installed a stage 2 colt cam.
My expectations have been wildly exceeded. I had some custom tuning done to match the cam and turbo. I don’t have to downshift out of 6th gear to pass; it keeps building power.
Thanks Mike!!

Team did an outstanding job
Needed a complete engine rebuild on 6.7 Cummins and Mike plus his shop team did an outstanding job. Communication was great throughout the process and the quality of work is even better. I highly recommend Automotive Engineering if you want a job done right the first time. 10/10

4. Studio Engine Werx
Website: http://studioenginewerx.com/
Address: 7870 Granada Rd
Contact: (720) 990-8162 | [email protected]
Hours:
- Tuesday – Friday: 8:30 AM – 5:30 PM
- Lunch Every Day – One Hour, Walk-Ins Not Available
Studio Engine Werx has a laser focus on imported cars that have been pushed to their limits. This is a mechanic who truly understands high-performance racing parts, handling brands like Audi and BMW with great precision.
The owner, Steve Choquette, uses over thirty years of machining experience to oversee every modification entirely in-house.
And because they operate on a strict schedule, they can dedicate ample time to removing stubborn carbon buildup from modern engines. You won’t find crowded waiting rooms here, just technical work focused on pure speed.
However, this exclusivity comes with a few drawbacks. They refuse walk-in clients and only return phone calls twice a day.
Plus, they require engine blocks to be delivered fully stripped. This makes them a great choice for serious racers, but a bit difficult for the average driver.
Customer Reviews:
Did a fantastic job
Steve does great honest work! It might of taken a little longer but thats bc I was sold (from a shop unrelated to Studio Engine Werx) a bad engine. He did a fantastic job and kept me in the loop the whole time. Thank you again SEW, you guys truly are making dreams come true!

Steve and Jen are fantastic!
Steve and Jen are fantastic! They really helped me out in a time of need and worked with me the best way they could. I really brought a disaster their way and they kept the best attitudes through the whole thing and I couldn’t ask for better problem solving and professionalism from a shop.
Thank you guys so much again, you are awesome!

5. Southeast Automotive
Website: https://www.seautoshop.com/denver-co-auto-engine-repair-rebuilds-replacement-service.php
Address: 2055 S Hudson St
Contact: (303) 756-8735 | [email protected]
Hours: Monday – Friday: 7:00 AM – 5:00 PM
A blown motor can derail your life almost as fast as needing DUI lawyers, but a trusted neighborhood garage makes the recovery process manageable.
Southeast Automotive has a long history dating back to 1958 and relies on master technicians with decades of experience. They start every job with a free diagnostic service to pull your vehicle codes and identify the issue.
As an authorized TechNet facility, they offer a nationwide warranty on all major overhauls. This is a great benefit because it ensures your car is covered even when you’re traveling far from home.
On the downside, the shop is small and can sometimes have a slower turnaround for heavy engine work.
You should also note that they’re closed on weekends. This might be inconvenient if you need to pick up your vehicle but can’t make it during their weekday business hours.
Customer Reviews:
Five stars all the way
I’ve taken my car into Southeast Auto a couple times now and have a few family members who have done the same. Southeast has always helped solve the problem and been transparent about repairs each time. The team has been friendly, knowledgeable, and very communicative. I’ve been hoping to find a trustworthy mechanic for a while now and am so thankful we came across this shop! Five stars all the way.
