Customer Reviews
Good product, fast shipping
I ordered a Low Temperature Stirling Engine. It arrived quickly, within 7 days. Works as described. Assembly was straightforward. Happy with the purchase.
Fun build, pretty neat
Got the MOC Car Engine Blocks kit, the V8 one. It was a really fun build for a couple of evenings. The instructions were clear enough, no missing pieces which is always a win. Looks pretty cool on my desk now. Definitely worth it if you like putting stuff together.
Detailed review of a Supercar MOC Kit
I recently ordered one of the Supercar MOC Kits, specifically the one resembling a W16 engine. The ordering process on the website was straightforward, and I received an order confirmation almost immediately. Shipping took around 10 days, arriving via standard mail in good condition; the box wasn't damaged. All the building blocks were present and sorted fairly well, which is a plus for such a complex model. The instructions were digital, accessed via a QR code, which was convenient on my tablet. Assembly was quite intricate, taking me several evenings, but the final model is impressive with good detail. I did notice one small piece had a slightly looser fit than others, but it didn't affect the overall stability. It's definitely a display piece and not really a toy. For anyone into complex mechanical builds, this is a solid choice. The finished product looks great on my shelf.
Consistent quality, reliable
This was my third order from EnginediyShop, this time for a Radial Engine Model. Like my previous purchases (a V12 building block kit and a High Temperature Stirling Engine), the quality was excellent. Shipping took about 9 days to reach me in California, which is typical for them. They're consistently reliable; I know what I'm getting. That's why I keep coming back for more projects.
Solid kit, but slow support
I bought the Single Cylinder Steam Engine model. The quality of the parts was good, and it runs smoothly once assembled. The assembly instructions were clear. However, I had a question about lubricating oil before it arrived and customer service took a few days to get back to me. Not a huge deal, but could be faster. Overall, a good experience for the price, just don't expect instant replies if you need help.
Good value for a first kit
I was looking for a V8 Engine Model Kit and found a good deal here. Shipping was free because my order was over $100. The kit arrived in about 8 days. Building it was challenging but rewarding. For what I paid, it felt like a really good value. I compared prices on a few sites, and this one offered the best overall cost with the free shipping.

Hey, thinking of getting one of the V8 engine kits. Do these things actually work or are they just for show? Like, will it move parts like a real engine?
Anyone know how long shipping takes to, say, California? Thinking of getting a gift for my dad's birthday next month and want to make sure it gets here in time.
