Shop was recommended to me by a fabricator friend. Didnt tell the shop who sent me and they were very honest in helping me decide what direction I want to go with my build. They are very down to earth.

Great Experience. They have always done amazing machine work for me.

I brought my truck to the Tachyon team and get the cam and lifts worked on as well as the suspension. Terry, Chris and the whole team were very professional knowledgeable and experts at their job. Very, very satisfied with the results of the work done on my truck and engine. Terry especially communicated often and did it with an honest, professional, and friendly demeanor the entire process. The price was fair and honest, I will not take my vehicles anywhere else moving forward. A job well done. With great appreciation and gratitude, Anderson.

Professional serviceWith knowledge and experienceJim.

Have used them a couple of times for machine work. They are my go to for machine work

Awesome place for your project car. Ive had blocks machined and bored here grate work top quality service.

These guys are awesome Ive been using them 4 over 15 years and never disappointed in the service

Takes forever to get a head shaved

Great people and awesome machine work for engine rebuilding!!! Jeff and Terry are super!

These guys did a major job on the 350 small block in my 1988 GMC Suburban 4-wheel Drive. This was more than five years ago. My engine.....still running as strong as the day I picked it up. If your engine needs a little pep or a lot, this is the only place I would rely on!

I have been doing business with the owner for many years and I will continue they do exactly what you ask them to do

A shop that can’t own up to their mistakes and rather consistently blame the customer is a shop worth never dealing with! STAY FAR AWAY FROM THIS PLACE AND ITS OWNER JEFF!

Brought a very expensive cylinder head to be cleaned, decked, and rebuilt. 75 miles later the head was eating its self and the owner Jeff who is very unprofessional refused paying up for any mistakes!! Legal case pending!!!! WISH I Could give less than a one star review, Do not bring your car or parts to this shop!!!

Went in today to get my hub bearing replaced. Great prices, fast, and great work! Very professional. I will not use anyone else!

Great customer service, fair pricing, knowledgeable staff. They are definitely our go-to for auto repair now.

I have them do my machine work for my motorcycle and Jeep among other things. They are always super fast friendly. Work is on point. And costs are very reasonable. With 25 years of motor work under my belt, I wouldn’t trust anyone else.

I have been bringing my FJ Cruiser here for years! These guys are honest..priced very fair and are excellent mechanics. It’s cost half of what a dealership to repair my truck. I never worry about being over charged or being taken advantage of.Terry & Jeff are fantastic!

😡👎 I DO NOT RECOMMEND THIS PLACE. They messed up a job and didnt want to give a refund. I told them we can go easy route or a long one taking my car to a dealer for inspection and to the court right after. They gave refund right away. Such a rip off. Dont go there. One star review well deserved.

Always do great honest work

I would not take a newer car with an electrical issue here. These guys seem to be good at engines, blocks, clutches, intakes, brakes cv joints etc. They did not have tools to diagnose an electrical issue. They did not charge me much but still 2 weeks of wasted time. One star now - turns out was a fuel pressure issue. Any decent shop would have check pressure on the rail.

Had ball joints pressed in a frame

Pretty laid back and honest feel to the place and people in general. Did they fix my issue? Well, I didnt really give them the time to do so, but from my short experience there, I think theyre alright. 👍

Great service. Very professional.

Tachyon is GREAT. All employees of Brooklyn Pizza go to Tachyon. These guys are sharp and fair. They will not gouge you. They are HONEST MECHANICS. We trust them with all our vehicles. We recommend them to any and all customers who have need of car repair. They will go out of their way to help you out of a jam. You will tell all your friends about them, once you experience this level of service.

Excellent service with integrity. Night and day from the Nissan dealership near by!

Very honest and friendly mechanics! My girlfriends Focus ran hot a couple times but I was unable to recreate the issue. Still wanted a mechanic to check it out before we attempted to make a road trip. They were unable to recreate it either (must have just been a fluke), but they offered great advice in case it happens again. They didnt try to replace anything I didnt need and since they couldnt find anything wrong they were extremely fair with the diagnosis fee. I definitely feel comfortable with their opinions and will bring all of my vehicles here in the future!

Great to work with. Excellent job on my short block

Great place

These guys are honest and professional will for sure be going back for any other issues.

Went to get a flywheel turned. They cleaned it up, and pressed a bearing for me. Turnaround was just a little more than an hour. Im happy with the results and price.

We really appreciate everything these guys do for us. They always get us in and out in a timely manner. They are easy to deal with and take good care of us. Thanks guys!

Best automotive shop in Jacksonville hands down

Its rare when you find a auto repair shop that is honest, does great work and fixes it right the first time. I highly recommend Tachyon Automotive. Great guys! Tell them Scott Lara sent you!

Said they would call in 2 days to let me know what was going on with my stuff. 9 days later I called seeing what was going on being that they never called me. On this call Jeff tried to sell me things I didnt need and lied to me about what was wrong with my stuff then said he would call back in 15 to let me know about the rest of the engine stuff I dropped off. Over 2 hours later I called again and he tried to sell me the same thing then said they were looking at it right then. The next morning I called to ask how much was done so I could pay for that and take my things. Jeff avoided my question 6 times and each time trying to convince me that I dont need my things. On the last time I asked he got upset and finally told me they never looked at my stuff and to just come pick it up then hung up on me. So they never looked at my stuff, tried to sell me work that wasnt needed and lied to try to sell it even though again they never even looked at it(his exact words), rude, and poor communication. Dont take your machine work here they will try to milk you for your money. Very unprofessional and disappointing.

Have used this shop as needed on and off for years with multiple vehicles. All the other reviews about honesty and great prices has been my experience as well. Good work, good people.

Did gears in my 87 mustang gt. Not but a year later the rear end was howling. Had to get them redone the right way.

These guys helped me out with a nightmare bolt! Great guys, Honest and very easy to work with. I highly recommend them. Ill be going back to these guys if I need any more auto help.

Excellent service accompanied by great knowledge.

Jeff,Terry and the whole gang do great work. Very knowledgeable and friendly. I will continue to use them for all my engine work.

Worked with Terry to get a poorly designed OEM part that failed replaced with an aftermarket part on my 370z. While the repair isnt typical, they still scheduled me in to have the work done. I was given a rough quote and they kept to their word while keeping me informed along the way. Props to Jake who did a majority of the tough work! Trustworthy people - Ill be back.

Hi how are you. I have some questions, my ford svt lightining truck is not running well I would like to know if that block in case of damage to any cylinder can be repaired or rebuilt and work properly again

These guys are awesome!!! Trustworthy, reliable repairs at very reasonable rates. Ive found my repair shop from now on. you need to check these guys out!

Have all my engine work done here!

Fantastic service fantastic people

Great place to get the work done on your heads or blocks

Great crew great workmanship.

THE best in Jacksonville. Period

Worst expire cr ever! I brought my heads there off my 5.4 to get cleaned up ported and one exhaust stud that was broke off in the head. First thing they did was said they would call in 2 days and no call. They took forever to port my heads which would be understandable if they did a good job but all they did was run a dremel down the ports to clean them up not much port work. Next they lost some parts of mine which I obviously made them replace werent happy about that and started getting annoyed with me. Lastly they never even extracted my manifold stud. Wouldnt recommend anyone there not even my sisters ex boyfriend. DO NOT GO THERE!

These guys were super nice and an absolute pleasure to deal with.

Took literally a year to finish building my 1.8l i4 engine. Only got it bored 20 over and new pistons. Had a valve cover leak AND main seal leak. Took the car back to ask them to fix the leaks, they didnt even find the main seal leak even though I told them oil was coming out of the front of the engine. Also charged me for the valve cover gasket install even though I had a warranty.

Good people lots of help would recommend them to everyone

Very happy with the service and fair price

Old school hot rod shop, excellent machine shop

MX1 operation well-run and excellent pricing

Honest guys who know their stuff and they charge reasonable prices.

Absolute worst machine shop in jax. They damaged my cylinder head and said its ok... They didnt even say anything until I payed and inspected it at my house. Never again will I go here...

Affordable Quick and friendly, Drop off got a call an hour later to pick up Very impressed..

Quality work and fair prices.

Fast, freindly and reasonably priced.

👍

Jeff and his staff are true professionals.

Knowledgeable and honest
