The Pinnacle of Audi engine rebuilding for your EA837 engine!

Customers now have a trusted source to get their 3.0L EA837 Supercharged engines rebuilt to extract new life out of them. Send your long block to us for our world class full engine rebuild. Curious about our rebuilds? Ask around about us! We have the knowledge and expertise required to deliver a superior rebuild all while having fixed public pricing. Outside of North America? We help customers worldwide! Our running rebuilds are bringing smiles per gallon in 5 different continents.

Not thrilled about removing your engine and reinstalling it? Contact us for a turn key rebuild solution.

We have brought back our non sleeved rebuild program! Non sleeved rebuilds will need to pass our in-house bore measuring inspection and must not have a variance of more than 0.0010" within a single bore. Engines that do not pass this criteria will either need to be sleeved or a waiver signed to continue the non sleeved rebuild.

We offer inspections free of charge for engines that are rebuilt. In the slim unfortunate event that your engine is not able to be rebuilt, we can source core parts for purchase. If you would like a basic inspection and tear down and not proceed with the engine rebuild, our charge is $750.00. The engine will not be re-assembled.

Customers must establish contact prior to shipping. Purchase of the desired engine rebuild stage in full is required before work begins. Shipping to or from our facility is not included. Local drop off and pick-up is available free of charge. Never shipped an engine? Let us help guide you through the process! We typically see shipping rates between $275-$500 one way within the continental United States. We recommend using www.goship.com

Long blocks are to be delivered to us without accessories. Accessories include: Oil Filter Housing, Water Pump, Power Steering Pump, A/C Compressor, Alternator, Accessory brackets, Oil Cooler, Exhaust Manifolds, Engine Mounts, Knock Sensors, Supercharger, Fuel Rail Manifolds, Injectors, Coil Packs, and Cam Sensors. Spark plugs can be left in the engine, but rebuilds will not include spark plugs.

Our engine rebuilds will REUSE your timing phasers. If your engine is known to have timing phaser issues, please contact us so that we can arrange for them to be replaced at an additional cost. We do not accept any liability on rebuilt engines with variable phaser issues.

We offer a 24 month warranty for any of our stage engine builds not used with an aftermarket forced induction system. We cannot warranty engines on forced induction as there are too many issues that can arise from custom tuning which are out of our control. Please ensure you are using new fuel injectors on all engine rebuilds as we do not cover fuel injection related failures. Our warranty does not cover any labor or parts to install/remove the engine from the vehicle. All warranty work is only available at our facility.

Engines must be shipped directly to our facility at the following address. Purchase and tracking needs to be completed and sent to AMTuned prior to engine arrival.

We are the only company in the world utilizing our proprietary block prep service. This in-house developed service allows us to run a factory bore size and not cheat by using a smaller OD sleeve and a tiny piston. This results in engines that are more powerful with factory displacement over the competition. Our service removes the risk of the vapor ports between the bores cracking behind the sleeves and leaking coolant down into the crankcase. Below is a picture of a block that did not have our block prep service. We removed the sleeves to find cracked coolant passages between the bores and visible signs of coolant entering the crankcase.
