Whether you're building a turbo street car, drift car, drag car, or dedicated race engine, sleeving the block is one of the best investments you can make for long term reliability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eAt 5150 Autosport, we don't sleeve blocks because it sounds good, we sleeve them because we've seen what happens when stock bores are pushed beyond their limits. High cylinder pressure, excessive heat, and years of abuse can lead to cracked cylinders, bore distortion, or engine failure. A properly sleeved block eliminates those concerns and gives you a solid foundation to build on.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWhy Sleeve Your M52TU \/ M54?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe factory aluminum bores work well for stock and mild builds, but once boost and cylinder pressure increase, they become the weak link.
