About Us

right_aLow Mileage Japanese Engines and Transmissions

We offer low mileage Japanese engines and transmissions imported from Japan, and technical support for our customers. I have been in the engine business for 40 years and have never seen as great a value as our engines and transmissions. These engines and transmissions have between 30 and 40 thousand miles. This is an estimate based on the average life of a car in Japan. The engine you get may have more or less miles. Our non turbo stock replacement engines come with a 6 month, unlimited mileage warranty, and our transmissions have a 3 month, unlimited mileage warranty. Our turbo stock replacement engines have a 3 month, unlimited mileage warranty. These stock replacement engines are sold as longblocks. Because they are out of cars from Japan, many of the accessory parts (manifolds, carburetors, distributors, other electrical items, etc.) that come with these engines are different from the USA model and are not covered by our warranty. The warranty does not cover any labor costs. ENGINESUS products are a much better choice than the mass produced rebuilt engines sold at parts stores, or used engines from salvage yards with high mileage. And for less money! So if you need to replace your stock engine or upgrade to a High Performance swap, we can take care of you.

Owning and operating a car in Japan is very expensive. Japan is a small country made up of several islands. It has a great public transportation system and very strict smog laws. Compliance with these laws by mandatory inspections can cost as much as 30% of the value of the car. An average parking space in Japan can cost $700.00 a month, more in cities. Gasoline costs 3-4 times what we pay for it. Cars are used mostly on weekends or daily to get to a train station. Cars with any body damage are considered unsafe by authorities and cannot be used. Labor is very expensive, so many cars with minor body damage and perfect low mileage engines end up getting recycled. And Japanese citizens have a propensity for owning and driving only the latest model cars. It’s a point of national pride for them. There are very few running cars in Japan over 6 years old. These conditions result in Japanese car owners not driving very much. The average life of a Japanese vehicle in mileage is between 30-40 thousand miles! In the USA we drive our cars 150,000 miles or more. (I have a customer with 325,000 miles on her 87 Honda Prelude SI!) So the engines and transmissions are removed from cars in Japan and shipped to us by ocean container. When the container arrives here, we unload the engines & transmissions. Then we inspect and test them. We do a leak down test, compression test, and oil pressure test. Those that successfully pass this quality control procedure are then high pressure washed. We then put them on pallets and secure them with bands and shrink wrap. Now they are ready to be shipped to customers throughout the United States. We have the ultimate recycling business!

We specialize in Subaru Rebuilt Engines. Our goal was to offer a very high quality engine at a fair price that people can afford. I think that we have achieved this goal. We build them in house, and each goes through the same process. The Subaru EJ2.5 Engine has an inherent head gasket issue and a “piston slap” issue, both of which we address.

Starting with our cleaning method, we clean the parts in a high pressure cleaning machine. Then we blast the block and heads in a baking soda blasting machine. Most rebuilders us a glass beading machine to clean these parts. Glass is abrasive and it is difficult to clean out the all of the glass residue from oil passages. Baking soda is non-abrasive and cleans out easily with water and compressed air leaving absolutely no residue. The Statue of Liberty was restored using this method!

We completely rebuild and resurface the cylinder heads. We resurface the heads with a milling machine which gives a much better finished surface than the spinning disc method which many rebuilders use. We also resurface every block with a milling machine. Some rebuilders do not resurface the block. We believe this to be a mistake, as one side of the head gasket is going on an unflat surface. We use a triple layered stainless steel head gasket coated in heat resistant Viton. They are made by 6 Star and are the best head gaskets we have ever seen made for Subaru. We bore out every block and put in new pistons with a good size skirt. The original Subaru piston has almost no skirt, causing the cylinder bore to wear in the middle, eventually causing “piston slap”. We use Hastings piston rings, which are very high quality rings.

The engine comes with a new factory Subaru oil pump and OEM (original equipment manufacturer) seals. The oil pan is installed also. We do not install timing components as doing so would increase the engine cost. This would be an unnecessary cost for many that have recently replaced those parts and can swap them over from their old engine. For those that need to replace all timing components and water pump, we offer a KIT for $300 that includes all new OEM parts.
