BuildBot rationale

Why these parts.

When you are serious about power, stock internals become the weak link. This forged internals kit gives your FA20 the foundation for 400+ HP with room to grow. JE forged pistons paired with Brian Crower valve springs handle boost without flinching. ARP fasteners provide the clamping force needed for high cylinder pressures. This is the package that separates track toys from real weapons.
