ENGINE BUILDING

Blueprinted
Performance.
Race Grade Reliability.

Precision assembly engineered for extreme horsepower and sustained high-RPM operation. Every tolerance is measured and verified before it leaves the shop.

Engineering Process

precision_manufacturing

01. Blueprinting

Complete disassembly, sonic cleaning, and multi-point dimensional inspection against factory and race tolerances.

memory

02. Precision Machining

Block decking, cylinder boring/honing with torque plates, line honing, and rotating assembly dynamic balancing to sub-gram tolerances.

03. Final Assembly

Assembled in a sterile environment, with bearing clearances mapped and set, ring gaps filed for the specific forced induction application, and fastener stretch measured for optimal clamping force.

Engine builds are priced against the block, the internals, and the power goal, not a flat rate. Send us your specs and Johnny will follow up with a real quote.

Technical FAQ

Frequently asked questions regarding our engine building parameters.

What is the break-in procedure? expand_more

We mandate a strict heat-cycle process followed by specific load-bearing dyno runs using break-in oil to seat the rings properly. Full procedural documentation is provided upon delivery.

Do you build for forced induction? expand_more

Yes. Forced induction builds are our specialty. We specify different piston materials, ring gaps, and head studs based on target boost levels and fuel types.
