The 2.0-liter 16-valve Renault F7R engine was introduced in 1994 as a sports engine for the company’s racing division. But civil modifications were also equipped with it, for example, the top versions of the first Megane.
The F-series include: F3P, F4P, F7P, F2R, F3R, F4R, F4Rt, F5R, F7R.
Having exhausted the possibilities for upgrading the 1.8-liter F7P engine, the engineers squandered it to 2 liters. Moreover, they increased not only the diameter of the piston, but also its stroke, completely preserving the riding character of the donor.
Otherwise, these units are very similar. So we have a cast-iron block, an aluminum 16-valve head, hydraulic lifters, an advanced intake manifold, a timing belt drive, and X-shaped lightweight pistons.
The differences are a different exhaust, a two-liter 4-2-1 spider, larger valves, its own oil cooler, control unit and other little things.
The engine was installed on:
- Renault Clio 1 (X57) in 1994 – 1997;
- Renault Megane 1 (X64) in 1995 – 1999.

Disadvantages of the Renault F7R engine
- Unreliable ignition coils are the main cause of engine tripping. And since they are made in a single module, if one breaks down, a block of four will have to be changed entirely.
- If the car stalls on the move, first of all it is worth checking the crankshaft position sensor, most often it is he who is to blame.
- Unstable operation of the motor is usually associated with the failure of the MAP sensor or severe contamination of the throttle.
- The weak point of this power unit is oil leaks, especially often it oozes through the crankshaft oil seal.
