- Engine blocks visit our hot tank before and after machining for a clean, finished appearance
- Brand new OEM Crankshafts are never cut / turned and receive a micro-polish treatment and balancing specifically for high performance applications. Additionally The crankshafts are cut for a keyway to allow the timing gear to be locked to the crankshaft. The balance shaft gear is also removed to reduce unnecessary rotating weight
- We use a brand new ford ecoboost 2.0 block with 2.3 internals, The 2.0 block has shown to be superior to the 2.3 block which has been known to crack. *Must utilize 2.0 head gasket when bolting on a 2.3 cylinder head.*
- The first step in the machining process is resurfacing. We pride ourselves on the surface finish (RA) we achieve as it is of the utmost importance in regards to head gasket sealing
- We utilize a three step honing process utilizing a 2.3L Ecoboost specific torque plate to ensure roundness. Our honing process is finished with a plateau hone for the absolute best cylinder wall finish and ultimate ring seating
- Manley Turbo Tuff I-Beam Connecting Rods
- Custom motor mount to utilize the 2.0 block in the 2015+ Ecoboost Mustang

We thoroughly inspect, blueprint, clean and assemble our engines in a clean room and most of the machine work is performed in house to satisfy our stringent requirements. We have had great success in building countless motors for every imaginable application from the weekend warrior to the all out race car.
