Took my Honda crank here to be balanced and polished. They called me to confirm a fear that there was some deep grooves on the journals that wouldnt polish out so a grind was needed. They did a great job on this part for me and I am very satisfied. Entire grind and polish came to $150 which is better than a new crank.Business hours for this shop are Monday-Friday 8-5, closed on weekends.

Wonderful place and great people.you need head work,block work piston,crank cam,turbo any engine parts gas or diesel this is the place for it.Always very helpful and kind.

Very good job had a 93 Honda civic dx hatchback that had a bad head gasket took the cylinder head off and had it took to twin city had the whole head rebuilt Ive had back for about 3 months now and everything is working as it should will definitely be using these guys in the future great job twin city ur awesome homies

Took my my 12 valve Cummins engine in for some prep work for performance parts, Steve was the only guy I talk to that was familiar with the work I wanted done. Knowledgeable guy and has been patient as I gather the custom parts to allow machine work to be finished. Great place!

Awesome Place awesome prices awesome people great work

Great group of people. Always helpful.

Excellent service.Excellent workmanship.Very reasonable.They can even rebuild your starter or alternator. Way better than the refurb junk at the Brick and Mortar stores.I trust them more over a factory crate SBC made who knows where.They did the work on my SBC 350 4 bolt main in my 1985 TA converted to a Bowtie motor and it is holding strong as new 10 years down the road and still pushing close to 375 hp!They will be straight up with you if you ever need any work done which is a rare quality and speaks to why they have been around for ages.

Very knowledgeable staff gladly made the effort to assist me to help find what I needed

Awesome guys and very smart great doing business there

What you need in stock.

I cant say enough good things about this shop. Theyre one of the few establishments left that actually cares about customer service and quality work.Ive had them service a 1999 Chevrolet 5.3 engine block and also a 1952 Ford 8N Tractor engine block, and both were spot-on and reasonably priced.No--they werent the cheapest of the machine shops I found when I was calling around for quotes--but I made the mistake of using the cheapest one (I wont name the business in Kingsport) on a previous project and Ill only say that after using Twin Cities Id be MORE than willing to pay the few bucks extra--it wasnt very much more at all and the quality of work makes it worth the difference.I would most certainly do business with these folks again.

Very helpful staff

Good service.

Very knowledgeable

Quoted one price on phone when picked up 550.00 higher.. told if dont like pick stuff up and find somewhere else to get done.

Not good work, not good people skills, not good with the services rendered or the money I paid. had to pay someone else to re-do their work because they wanted to charge me more money and wait weeks to do something that was verbally discussed over the phone and in person.

Done a great job on machine work on my 5.9 cummins. Would recommend to any one. A great bunch of guys.

Fast service, good work on valve job preformed for me
