Nissan SR20 Engine CAD - 3D Model (STEP) [Item: SBU]

Contributor: Scottify Designs

The Nissan SR20 is a 2.0-liter (1,998 cc) straight-four, four-stroke, liquid-cooled, gasoline engine from Nissan’s SR family, produced from 1989 to 2002. There are two engine variants, the SR20DE (NA) and the SR20DET (Turbocharged). As far as we know, the exterior of the engine is the same for both and only internal components are different.

Precision bare engine CAD model of the Nissan SR20, created using a high-resolution 3D scan as the primary reference to ensure accurate external geometry and real-world proportions.

This model represents the external geometry of the engine block and cylinder head and is suitable for projects involving SR20DE and SR20DET variants where accurate mounting, packaging, and clearance data is required. It is intended for design reference and layout work rather than internal engine analysis.

Features & Coverage

• External geometry of engine block and cylinder head

• Engine mounting boss locations

• Bellhousing / transmission mating face

• Accessory mounting interfaces

• Oil pan flange and timing cover exterior

Commonly Used For

• Engine bay and chassis packaging

• Custom engine mount and bracket design

• Exhaust, intake, and accessory layout

• Clearance and interference checks

• Scan-based CAD concept and manufacturing workflows

Compatibility

• Nissan SR20DE and SR20DET applications

• Suitable for common RWD SR20 configurations

Note: Minor external variations may exist between model years and vehicle platforms.

Important Notes

• CAD geometry is based on real scan data

• Internal components (pistons, rods, crankshaft, valvetrain) are not included

• Turbocharger, manifolds, and accessories are not included unless stated

• Model is intended for external reference and packaging use
