EFR 74mm T4 Turbine Housing BorgWarner 12741008001

BorgWarner turbocharger turbine housing — EFR 74mm T4. This is a build component selected by SPECIFICATION rather than by a single vehicle application: match the frame size, flange, wheel size and A/R to your build. If you are not certain what your build needs, ask a tech before ordering.

What it does

The turbine housing routes exhaust gas across the turbine wheel and its A/R ratio sets how quickly the turbo spools against how much it flows up top. A cracked housing leaks drive pressure and heat; a different A/R changes the whole character of the turbo. Replacing it restores a sealed, correctly sized exhaust side.

How to choose

• Match the compressor and turbine wheel sizes to your power target and drive style
• Match the turbine housing A/R and flange to the manifold and downpipe you are running
• Confirm the oil and coolant feed arrangement matches your engine
• Check the part number against the component you are replacing

Fixes

• a cracked or warped turbine housing
• an exhaust leak at the turbo
• a spool or top-end change wanted from a different A/R

What's included

• the turbine housing at the A/R stated in the listing
