Installation summary

This expert-level engine modification requires professional installation by a skilled machinist equipped with specialized CNC boring and decking equipment, making it completely unsuitable for DIY enthusiasts. The engine block must be completely stripped, thermally cleaned, and precisely bored to accept the centrifugally cast ductile iron sleeves with exact interference fits. The most critical factor to watch during the machining and pressing process is maintaining absolute deck flatness and preventing block distortion to ensure proper head gasket sealing under extreme boost. Because improper sleeve installation can lead to catastrophic engine failure, professional machine shop installation is strictly required for this upgrade.
