P2M Solid Polyurethane Motor Mounts – Nissan S13 / S14 / S15 | SR20 / KA24 | HRC-80 Urethane | -5mm Lower Than Stock

The P2M Solid Polyurethane Motor Mounts for the Nissan S13, S14, and S15 are direct-fit solid urethane engine mount upgrades — replacing the factory rubber engine mounts with solid HRC-80 hardness urethane units that eliminate excessive engine movement at high RPM and high horsepower output, improve power transfer to the rear wheels, and lower the engine approximately 5mm closer to the centre of gravity for improved track performance. Compatible with the SR20DET and KA24DE engines. Designed to be paired with P2M's solid urethane transmission mount (P2-TMKNS13-HC) for a complete solid drivetrain mount upgrade on the S-chassis. Phase 2 Motortrend (P2M) is a respected JDM performance and accessories brand known for their quality drivetrain, suspension, and interior accessories for popular Japanese performance platforms.

Key Features:

• Solid HRC-80 urethane construction — manufactured from HRC-80 hardness urethane — a solid mount that eliminates the compliance and deflection of the factory rubber mounts under high-load conditions
• Eliminates excessive engine movement — the factory rubber engine mounts allow the engine to move excessively under high RPM and high torque loads — the P2M solid urethane mounts keep the engine firmly in position under all operating conditions
• -5mm lower than stock — the P2M mounts are designed to be approximately 5mm lower than the factory mounts — lowering the engine closer to the centre of gravity for improved weight distribution and track performance
• Improved power transfer — keeping the engine steady reduces drivetrain flex and improves the efficiency of power transfer from the engine to the rear wheels — a meaningful improvement on high-horsepower S-chassis builds
• SR20 / KA24 compatible — correct for S13, S14, and S15 applications running the SR20DET or KA24DE engine
• Pairs with P2M transmission mount — designed to be paired with P2M's solid urethane transmission mount (P2-TMKNS13-HC) for a complete solid drivetrain mount upgrade
• Direct-fit — engineered for direct-fit installation on the S13, S14, and S15 — uses the factory engine mount locations
• P2M quality — manufactured by Phase 2 Motortrend, a respected JDM performance brand

Why Solid Motor Mounts on the S-Chassis?

• Factory Rubber Mount Limitations: The factory S-chassis engine mounts use rubber bushings that provide compliance — absorbing engine vibration and reducing NVH for a comfortable street driving experience. However, this compliance allows the engine to move under high torque loads — particularly on modified S-chassis builds with increased power output. Engine movement under load reduces power transfer efficiency, causes inconsistent throttle response, and can contribute to drivetrain wear over time.
• Solid Mount Advantage: The P2M HRC-80 urethane solid mounts eliminate engine movement entirely — the engine stays firmly in position under all operating conditions. The result is improved power transfer efficiency, more consistent throttle response, and reduced drivetrain flex. On a high-horsepower SR20DET or KA24DE build, solid engine mounts are a foundational drivetrain upgrade.
• -5mm Lower Engine Position: The P2M mounts' -5mm lower engine position is a meaningful performance detail — lowering the engine's centre of gravity improves the S-chassis's weight distribution and reduces the engine's contribution to the car's overall centre of gravity height. For track-focused S-chassis builds where weight distribution and centre of gravity are performance variables, the lower engine position is a genuine advantage.
• NVH Trade-off: Solid engine mounts will transmit more engine vibration into the cabin than the factory rubber mounts — this is the expected trade-off for improved performance. On a dedicated performance or drift build, this trade-off is acceptable and expected. For daily-driven S-chassis builds, the increased NVH should be considered before installing solid mounts.

Complete Solid Mount Package — Pair with P2M Transmission Mount:

P2M recommends pairing the solid motor mounts (P2-EMKNS240-HC) with their solid urethane transmission mount (P2-TMKNS13-HC) for a complete solid drivetrain mount upgrade on the S-chassis. The combination of solid engine mounts and a solid transmission mount provides maximum drivetrain rigidity — keeping both the engine and transmission firmly in position under all operating conditions for the best possible power transfer efficiency and shift precision. Both products are available separately from Straight Six Imports.

Specifications:

• Brand: Phase 2 Motortrend (P2M)
• Part Number: P2-EMKNS240-HC
• Material: Solid HRC-80 hardness urethane
• Type: Solid engine mounts (pair)
• Engine Position: Approximately -5mm lower than factory
• Engine Compatibility: SR20DET / KA24DE
• Application: Nissan S13 (240SX / 180SX / Silvia) / S14 (240SX / Silvia) / S15 (Silvia)

Fitment Information:

• Nissan S13 — 240SX / 180SX / Silvia — SR20DET / KA24DE
• Nissan S14 — 240SX / Silvia — SR20DET / KA24DE
• Nissan S15 — Silvia — SR20DET
• Direct-fit — uses factory engine mount locations
• Note: Verify your specific S-chassis model and engine configuration before ordering. The -5mm lower engine position may affect clearance with surrounding components — verify clearance after installation. A solid engine mount will increase engine vibration NVH in the cabin compared to the factory rubber mounts — this is expected and normal on a performance build. Professional installation recommended.

What's Included:

• P2M solid polyurethane motor mount set — HRC-80 urethane — Nissan S13/S14/S15 SR20/KA24 (P2-EMKNS240-HC)
• Refer to P2M's product documentation for complete hardware contents and quantity

Installation Notes:

• Professional installation recommended — engine mount replacement requires supporting the engine during mount removal and installation
• Support the engine with an engine hoist or engine support bar before removing the factory mounts — the engine must be supported to prevent damage to surrounding components during mount replacement
• Verify correct clearance between the engine and surrounding components after installation — the -5mm lower engine position may affect clearance with the subframe, steering rack, or other underbonnet components
• Torque all mounting hardware to the correct specification — refer to P2M's installation documentation for correct torque values
• Inspect the transmission mount and other drivetrain mounts during installation — consider pairing with P2M's solid transmission mount (P2-TMKNS13-HC) for a complete solid drivetrain mount upgrade
