- Remove hoses and exhaust
- Take off the intake manifold
Once everything is disconnected, use the engine hoist to lift the engine out of the bay. Carefully place it on a stable surface for further disassembly.
Step 3: Disassemble the Engine
With the engine out, disassemble it by removing the cylinder head, oil pan, and other necessary components. Take care to label and organize parts to ensure a smooth reassembly process. Inspect the old components for wear and damage, as this can affect performance.
- Remove the cylinder head
- Take off the oil pan
- Label and organize parts
- Inspect old components
Step 4: Install the RE-Design 2.5L Kit Components
Now it’s time to install the RE-Design 2.5L Kit components. Start with the new crankshaft, followed by the pistons. Ensure that you follow the manufacturer’s instructions for proper installation and torque specifications. Next, install the performance camshaft, ensuring that it is aligned correctly for optimal performance.
- Install the new crankshaft
- Install pistons with proper orientation
- Align and install the performance camshaft
Step 5: Reassemble the Engine
Once all new components are installed, reassemble the engine by reversing the disassembly steps. Make sure to use new gaskets and seals to prevent leaks. Reattach the oil pan, cylinder head, and any other components that were removed.
- Use new gaskets and seals
- Reattach the oil pan and cylinder head
- Ensure all components are secure
Step 6: Reinstall the Engine
With the engine fully assembled, carefully reinstall it into the engine bay using the engine hoist. Reconnect all electrical connections, hoses, and the exhaust system. Make sure everything is properly secured before moving on to the next step.
Step 7: Final Checks and Fluid Replacement
Before starting the engine, perform a final check to ensure everything is connected correctly. Refill the engine with new oil and replace the oil filter. Fill the cooling system with new coolant. Double-check all connections and ensure there are no leaks.
- Check all connections
- Replace oil and filter
- Fill cooling system
- Look for leaks
Step 8: Start the Engine
With everything in place, it’s time to start the engine. Monitor for any unusual sounds or leaks. Allow the engine to reach operating temperature and check the performance. Take your BMW E30 for a test drive to experience the improvements firsthand.
Performance Gains and Benefits
After installing the RE-Design 2.5L Kit, drivers can expect noticeable performance gains. The increase in displacement results in enhanced horsepower and torque, making the vehicle more responsive and fun to drive.
