Best machine shop in the valley. The staff is very knowledgeable and always have your best interests in mind. Pricing is fair for the quality of service.

Best engine machine shop I have ever done business with. They are fair, honest and reliable. I have done business with Northwest Motor Machine since 2008 and I would not consider going elsewhere.

We’ve been sending all of our machine work out of state for the last 9 years UNTIL I was told about NWMM. They have done several jobs for my shop over the last year and I’m very happy with the quality of not only their work, but their friendliness and promptness. It’s not easy finding a machine shop that can do what we need on Porsche engines.
