The Next Generation of 2.0K Engines

Since 2006 at VGKracing we make a 2.000 c.c. evolution of the Rover K Series engine.

After more than 8 years of successful 2.0K engine sales we have decided to take the next step in the evolution of this engine with the most advanced materials, computer designs and weight reductions.

After more than 11 months of intensive work we finally have the next generation of the Rover 2.0K engine.

This evolution of the 2.0K engine is due to the spirit of overachieving, reliability, quality and accuracy that we have and characterize VGKracing in its product improvement. All parts used in this engine were successfully tested during more than 6 months in the most extreme conditions.


2.0K
Engine “Prometheus Mark V”

Prometheus was a Titan who with his great cunning stole fire from the Gods and gave it to the humans.

Likewise at VGKracing we used the cunning and the latest engine design software to design and test the parts with the aim to increase power obtained from fire.

Prometheus Mk V is a revolutionary engine concept.

Using the latest digital design techniques and computer simulations, we have designed a new type of engine based on the quest for pure performance and absolute reliability.

By using this software we have made an engine with higher-quality parts and less weight, to achieve maximum performance and reliability.

Tips for starting engine

- Do not turn the crank without the correct torque on the cylinder head bolts. This is to prevent the main bearings from becoming oval.

- Fill the oil filter several times until completely soaked then put in the engine.

- Before starting the engine the first time, unplug loom injectors and then crank the engine for 5 seconds, repeat this 6-8 times to load all the oil circuit.

- If you are going to have the short block without mounting the cylinder head or without starting the engine, before mounting the cylinder head pour a little oil on each piston by the side of the top piston rings for the oil to gradually transfer and lubricate the liners.

- If the cylinder head is mounted, but you are not going to start the engine, remove the spark plug and pour the oil through this hole, then move the engine from side to side so the oil does not remain in the piston crown.

- This 2.0K engine has different thermal behavior then a 1.8K.

- Before going directly to the races, check the oil and coolant temperature simulating race conditions.

- Typically in a 2.0K engine, the oil and coolant temperature is lower (if you use a 71/74 degrees thermostat).

- Anyway, it is not recommended ending a rolling road session and going directly to a race without knowing the thermal behavior of the engine.

Note: to obtain the maximum performance and reliability it is necessary to ensure that the fuel supply at high rpm is perfect, since the fuel help cooling the pistons and prevents any damage due to overheating. An insufficient fuel supply will produce melting or burning of the pistons. We recommend using a wideband sensor, Baro sensor and a perfect map for the engine.

Tips for street break-in engine

-During the first 3000 kms always check oil level before starting the engine because the oil consumption is greater.

-For proper piston rings adjustment, alternate between 3200/4200 rpm, do not maintain same rpm for constant period of time, this will help prevent abnormal oil consumption.

-During the first 200 kms you have to use 20W50 mineral oil, never synthetic and do not exceed 4200 rpm approx.

-After 200 kms delete the used mineral oil and filter and put again mineral oil and filter new.

-After 3000 kms put synthetic oil into engine and new filter, not exceed 4500 rpm.

-After 4300 kms and before going to the rolling road, do not exceed 5000 rpm.

-After 5000 kms you can go to the rolling road to complete the ECU map.

-When the ECU map is finished optionally you can put a Metal Lube "Formula High Performance" into the engine.

Tips for race break-in engine

-For proper piston rings adjustment, alternate between 3200/4200 rpm, do not maintain same rpm for constant period of time, this will help prevent abnormal oil consumption.

-During the first 200 kms you have to use 20W50 mineral oil, never synthetic and do not exceed 4200 rpm approx.

-After 200 kms delete the used mineral oil and filter and put again mineral oil and filter new.

-After 1000 kms, do not exceed 4500 rpm.

-After 1500 kms put synthetic oil into engine and new filter before going to the rolling road, do not exceed 5000 rpm.

-After 2000 kms you can go to the rolling road to complete the ECU map.

-When the ECU map is finished optionally you can put a Metal Lube "Formula High Performance" into the engine.

NOTE: the crank, con rods or pistons for the 2.0K engine are not sold separately, this purchase option is ONLY for owners of VGKracing 2.0K engine as spares.
