IHI

IHI for Porsche

IHI turbocharger technology is widely used across automotive and industrial applications, and where IHI units or related components are listed for Porsche at Design911, they can form part of both standard replacement and performance-focused setups.

A Quick Look at IHI

IHI supplies a wide range of turbochargers from small ones for automobile engines to large ones for land and marine power generators, and has already produced more than more than 100 million turbochargers for automobiles. We have development, production, and sales bases also in the U.S., Italy, Thailand and China, and are growing our business worldwide

Choosing the Right Fit for Your Porsche

Where IHI is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector or flange type where relevant.

• Typical reasons to replace engine rebuild parts include loss of compression, excessive oil consumption, abnormal noises, or internal wear found during inspection, and many owners renew chains, guides, bearings, seals, fasteners, and gaskets while the engine is apart to avoid repeat strip-downs.
• Typical reasons to replace turbo and intercooler parts include loss of boost, smoke, oil leaks, excessive shaft play, or performance issues linked to boost control, and many Porsche owners also upgrade charge-cooling components to manage intake temperatures and support reliable power.
• Common engine rebuild symptoms include low or uneven compression, heavy oil use, smoke under load or on overrun, persistent oil leaks, unusual knocking or rattling with RPM, metallic debris in the oil, low hot-idle oil pressure, overheating from internal friction, and misfires that remain after basic ignition and fuelling checks.
• Common turbo/intercooler symptoms include whining or siren noises, blue smoke under boost, slow spool or low boost, hissing from boost leaks, oil in intercooler pipework, overboost/underboost faults, heat soak with high intake temperatures, poor fuel economy, and misfires under load when boost control is unstable.
• Before committing to an engine rebuild, practical checks include compression and leak-down testing, borescope inspection, oil and filter analysis, and confirmation that ancillary systems are not the root cause of the symptoms.
• For turbo issues, pressure-testing the boost system helps distinguish between a failing turbo and a simple boost leak, and many specialists recommend renewing restricted or aged oil feed/return lines to protect a new or rebuilt turbo.

Engine Rebuild Parts — Engine rebuild parts are typically changed during a planned rebuild or when symptoms point to internal wear such as loss of compression, heavy oil consumption, persistent leaks, or abnormal noises; because labour is the major cost, many Porsche owners replace bearings, chains, guides, seals, gaskets, and hardware together to improve reliability and reduce the chance of another strip-down.

• Carry out compression and leak-down tests, borescope inspections, and oil/filter checks before deciding on a full rebuild, and consider renewing hard-to-access wear items while the engine is apart.
• Smoke does not always mean a rebuild is required, as issues such as an AOS/PCV fault or oil overfill can mimic more serious problems, so confirm the root cause with proper testing.

Turbo Chargers / Intercoolers & Parts — Turbochargers, intercoolers, and associated pipework or hardware are replaced or upgraded when boost is low, smoke or oil contamination is present, or components have become worn, cracked, or heat-soaked; in Porsche applications, maintaining stable boost and charge temperatures is critical for consistent performance and long-term reliability.

• A boost leak can feel similar to a failing turbo, so pressure-testing the system is an important step before replacement, and inspecting oil quality, intake tract cleanliness, and shaft play helps confirm turbo condition.
• When fitting a new or rebuilt turbo, many workshops recommend renewing oil feed and return lines to avoid restrictions that could quickly damage the replacement unit.
