This is our baseline for anyone pushing a B58 past what the factory internals were ever built to survive. Stage 1 covers the rotating assembly, head hardware, and sealing, everything that has to hold when boost and timing start climbing. It is built to safely support tuning up to 1,000 WHP, not a promise that your engine makes 1,000 WHP out of the box. That number is a ceiling, and we build with margin above it on purpose.

Send us your engine or buy a core from us and we build the whole thing start to finish. Either way it comes back ready to run once it's through break-in.
