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!!!

I DO NOT RECOMMEND THIS PLACE. They messed up a job and didn't 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. Don't go there. One star review well deserved. …

They were great! I travelled from out of town and my car went out of service. They took the time to help me even after closing so I could get back on the road. I'm so thankful for them because I made it to my destination on time and at a great rate. Would recommend …

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!

Worked with Terry to get a poorly designed OEM part that failed replaced with an aftermarket part on my 370z. While the repair isn't typical, they still scheduled me in to have the work done. I was given a rough quote and they kept to their

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 didn't need and lied to me about what

I had a 2.0 T mk 6 engine built . I’ll will say the newer employee who answers the phone is not a very pleasant person. Bad attitude and doesn’t really care to help you or answer questions. The other guys are really nice and easy to talk to.

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

I thought I had found the right place to get auto work done,but I'm starting to rethink this. Took my van in for not starting,sudden shut off right in the middle of driving,they said it was the wiring harness after months of them having my

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 didn't even find the main seal leak even

I took my head off of a 1965 Mustang inline 6 to be resurfaced and valve seals replaced. When I got the head back from Tachyon and placed it on the block and got everything torqued down the head was leaking from the freeze plugs. I don’t

Great work on the Axle job. Idk why Why Jeff thought I was a dumb girl I did ask the gentleman to please check my tires as the indicator is on and I know that PSI was short he tells me oh it's the dummy light and needs to be worked on.I

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 brought in a 1965 Ford Mustang 200cu in 6 cyl. to rebuild as compression was 115 and needed to be factory 155-165. The long block rebuild completion took 4 month, $2300 and final compression is 120. The motor still runs very badly &

Very honest and friendly mechanics! My girlfriend's 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

I brought my 1984 corvette in for some much needed maintenance to the suspension and ignition timing. Jeff, and staff, exceeded all my expectations. My car has never ran this well - they completely dialed it in. Best mechanic shop in

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

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

Pretty laid back and honest feel to the place and people in general. Did they fix my issue? Well, I didn't really give them the time to do so, but from my short experience there, I think they're alright. …

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

Shop was recommended to me by a fabricator friend. Didn't 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.

Can’t even put on a battery terminal. Used some cheap universal kit and the positive terminal was too small for my battery lead, so they hammered it on, damaging the post and resulting in leakage

It's 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!

Absolute worst machine shop in jax. They damaged my cylinder head and said it's ok... They didn't even say anything until I payed and inspected it at my house. Never again will I go here...

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.

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

These guys are the BEST! I will be a customer for life, and I tell everyone about them. They were honest, didn't try to over sell me on other work, and gave me a very good price!

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!

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!

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. I'm happy with the results and price.

This shop is busy because they do good work. Nice friendly staff who explained everything before the work was done. I highly recommend Tachyon automotive.

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

They fixed our Mercury Milan after two other places could not. One was Ford on Atlantic. Reasonable price too. They are a true vehicle repair shop.

I’ve been using this shot for years. They definitely deserved a five star when I found them 15 years ago and they still deserve five stars today!

Very good work, very good prices, not fast. I've been there two separate jobs and both were ending up 4 to 6 days later than quoted

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

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.

Fixed my window regulator for a reasonable price. When other shops tried to over charge me. It was done in a day.

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

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

Absolutely wonderful to deal with and super professional and fantastic to deal with. Highly recommended!

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