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.

Grab your popcorn and prepare for a read: I first came across AutoShop Machine Services while I was searching for a reputable machine shop to take my B18B1 block to have built. Many shops prior to contacting Greg straight up either shot me down or gave me some extraordinary wait time. I called the shop, explained to Greg what exactly I was looking to do and was told to call back after a couple weeks and he’d be able to give me a drop off date. On that second call, I was given a day to drop off the block along with the parts. This was a full short block build on OEM sleeves. Pistons, Rods, Crank, Girdle, and a slew of other new parts were going into this block. After he inspected the parts he gave me a more than reasonable wait time for the new motor to be balanced and built. We talked about my ultimate goals for this motor which was a fun turbo street car that sees light track use. Power goal was 400whp at 18psi and so he built the block accordingly. A couple months later I one day get the call that my block is ready for pick up and I schedule a time to come by the shop. Upon first sight everything looked amazing, the block was extremely clean with all the new parts installed. I paid him the extremely reasonable price for having all that work done and took the block down to my mechanic. To make a long story short, I found out that my cylinder head requires machine work as well as a freshen up. Race car parts aren’t meant for longevity, and I was using a cam and spring combo that ended up chewing away my GSC T1 cams. I talked to Greg about my newfound dilemma and he explained to me the best way of going about it. I dropped off my cylinder head at his shop and we talked over what it needed. New valves, valve exhaust valve guides, and valve seals.I purchased everything then dropped the parts off the following week. Greg took no time cleaning, machining, and reassembling the head. I picked up the head and dropped it off to my mechanic to have completely new parts put in, going the OEM route this time to ensure maximum longevity on my new build. Greg informed me of the proper first start procedure and gave me key knowledge on the very nuanced aspects of a successful break in process. Things you’d never learn until you actually ran into certain situations or experiences, GOLD! On the day of start up, my tuner is present to ensure everything goes flawless and after all that time, effort and money I was very happy when the first start up went without a single hiccup. No leaks, no weird noises, no smoke, just a very quiet and smooth running engine. Music to my ears. We high idle the car immediately to break in the new cams and dump that oil, just as Greg instructed to after about 20 minutes of run time varying the load and rpms. Greg informed me that that first dump used oil should look like little glitter, actually what I saw I would describe as even finer than glitter. It looked like extremely fine, silver dust in the oil. I could not even see it unless I shined my flashlight directly on the oil. My mechanic looked at me and said “That’s amazing.” This motor was built by a perfectionist and it shows. I have had motors built before and never have I seen such little particles on the first start up, they are usually a lot more noticeable. I was almost at a loss for words. I’ve been boosting away at 15psi on an extremely conservative tune, dyno session scheduled for next month. My tuner mentions how well built and easy to tune my car has been. She feels extremely healthy and turbo spools quicker than my last setup, even though I went from a 2.0L to a 1.8L. Greg worked some magic on the cylinder head! I honestly could not be happier with my experience with AutoShop Machine Services. They will be my go-to machine shop for everything! UPDATE: made 430whp 300lbft @ 16psi on the dynapack hub dyno. Made it with extreme ease, and the oil change following the dyno session was extremely clean. My magnetic drain plug didnt have anything on it. Greg is an absolute legend.

Gregg did a fantastic job of rebuilding the head on a 2006 Prius 1.5 L engine and had it done in a timely manner. Very happy with his workmanship iI would use him again in a heartbeat
