Here’s the short answer:
Turbochargers cook oil. The H22 already has oiling concerns (the balance shaft seal and oil jet bolts are known weak points). When you add a turbo, you add a red-hot bearing housing that spikes oil temperatures to 250°F+. how long is turbo-charged prelude
Now go boost that H22. Just do it smart. Here’s the short answer: Turbochargers cook oil
Before we discuss the turbo, we must honor the base platform. A stock Honda H22A (2.2-liter DOHC VTEC) or H23A non-VTEC engine is renowned for longevity. With proper maintenance—timing belts every 60k miles, regular oil changes with high-zinc content, and valve adjustments—a naturally aspirated Prelude will easily surpass 250,000 miles. Now go boost that H22
To understand the length, you have to understand the context. Turbo-Charged Prelude (released in 1992) is actually a designed to set up the main event: the full-length feature Fast Money (also known as Fast Money or Fast Getaway II in some markets).
