Introduction
The installation of Renault hemispherical engines in Lotus Europa requires careful consideration of various components, including engine mounts, exhaust systems, cooling systems, and fuel systems.
Engine Selection
The selection of the right engine is crucial, with options including French and U.S. engines, each with their own specifications and requirements.
Fuel Systems
Fuel systems include downdraft and side-draft carburetors, as well as fuel injection systems. The choice of fuel system depends on the engine and performance requirements.
Cooling Systems
Cooling systems are critical, with the need for oil cooling devices and high-volume fans. The original Europa cooling system may be inadequate and requires modification.
Exhaust Systems
Exhaust systems require modification, with options including 4-into-2 headers and silencers. The original exhaust system cannot be used with hemi-head engines.
Motor Mounts
Motor mounts require modification, with the need for extensions and spacers to fit the hemi-head engine.
Clutch and Flywheel
The clutch and flywheel require modification, with the need for a heavy-duty clutch and flywheel to handle the increased power of the hemi-head engine.
Oil Cooling
Oil cooling is critical, with the need for an oil cooler radiator and remote oil filter mount.
Starter Motor
The starter motor may need to be replaced with a heavy-duty unit to handle the increased power of the hemi-head engine.
Alternator and Pulleys
The alternator and pulleys require modification, with the need for a special alternator pulley and belt tensioning system.
Engine Front Cover
The engine front cover requires modification, with the need to remove the air conditioner pulley and plug the opening.
Sender Units and Gauges
Sender units and gauges require modification, with the need to transfer the original sender units to the new engine.
Cylinder Head
The cylinder head requires modification, with the need to eliminate restrictions in the inlet and exhaust ports.
Rocker Covers
Rocker covers require modification, with the need for cast alloy rocker covers to provide extra heat dissipation.
Piston Wrist Pins
Piston wrist pins require modification, with the need for high-compression pistons and special wrist pins.
Lubrication Holes
Lubrication holes require drilling through the rod bushing.
Final Caution
Before installing the new engine, it is essential to inspect other components, including the transaxle, clutch, and suspension, to ensure they can handle the increased power of the hemi-head engine.
