Customer feedback
Took the head of a 3 cylinder diesel tractor engine in for resurfacing. Greg did a great job and I had the head back next day. He gave me good technical advise on checking the valves. Look forward to doing business with him again on future machining needs.
Robert B.I brought my subaru heads to Greg to get resurfaced and he had them ready the next day. He did an awesome job and it was a great price. He was also very friendly and helpful! I will definitely go to him again if needed!
Kevin K.Greg rebuilt a junkyard 7MGE head I had to buy due to my own mistake and it runs like a dream. He saved me a ton of headache and also gave me a few tips for rebuilding the bottom end of the engine myself.
Christopher C.Did an OEM refresh on my WRX heads. 10/10 service, very punctual and clear communication and was very thorough with me about engine break-in ect. Above and beyond service, would not hesitate to work with again.
Austin C.10/10 great work great guy. Dropped off my b20 cylinder head for cleaning, test and resurfacing. He also removed a snapped bolt that went to the exhaust manifold. Exceeded my expectations and gave me his tips to do before & after installing the head. Runs and drives with no issues.
Nick B.What a great machine shop! I only had a small job - extracting a sheared bolt out of a fork tube from a 50 year old Honda motorcycle. Greg took my job right in and turned it around with astonishing speed for a super fair price. Great guy, great shop, great find.
Tom S.A picture is worth a 1000 words and this one should say 2000... So lucky to have stumbled into this machine shop... Hands down the fastest machine shop in the entire region! Owner Greg is incredibly knowledgeable, articulate and produces only the highest quality work.
Kurt L.5 stars all the way. I dropped off a Toyota 4AGE long block and Greg gave me an estimate of 5 weeks, provided there was nothing seriously wrong. In that time he replaced the bearings, rings, rebuilt the head, and had it ready for me on time and under budget. I'll be going to him for all my engine machine work projects from now on!
