JUBU cooling upgrade 2GR
With the OEM thermostat and OEM waterpump pulley, the 2GR-FE engine in Lotus cars tends to run slightly too hot. This leads to higher wear and tear on the engine and its periphericals. If the car is freqently driven in regions with hot climate and/or on race tracks, the cooling issue becomes even more crucial regarding performance and engine health.
The JUBU cooling upgrade comes with a thermostat that opens earlier (on lower temperatures) and an upgraded waterpump pulley that improves the effectiveness of the water pump (higher volumetric flow of the engine coolant).
To be safe regarding ideal engine temperatures - even on very high outside temperatures or hard trackdays/racing, the JUBU cooling upgrade is highly recommended. It ensures in a very cost-effictive way an optimal engine temperature, helps to unleash some additonal power/response und prevents the engine and other components from unnecessarily high wear and tear caused by running permanently slightly too hot.
Benefits
- Lower cooling water temperatures (which are more gentle to the engine and prevent it from too much wear and tear)
- Lower oil temperatures (which are more gentle to the engine and prevent it from too much wear and tear)
- Lower temperatures in the engine bay (which are more gentle to all components and prevent them from too much wear and tear)
- Inexpensive means to lower engine/engine-bay temperatures significantly
- Plug&Play - parts replace OEM part without the need of any further adaptations, fully retrofittable
Details
- Water pump pulley made of high-strength aluminium, manufactured on precise CNC machinery
- Developed by JUBU Performance, extensively tested on roads and tracks
- Indispensable in countries with frequently/permanently high outside-temperatures or for trackdays and racing (on trackdays or very sporty road driving even in regions with moderate/cold climate conditions)
- Full daily street-driving capabilities ("Road & Track" variant). At very low temperatures and with very little engine load (really slow cruising) the message "low water temperature" may sometimes light up
Fits for
- all Exige S3 models (V6)
- all Evora models
- 3-Eleven
- Emira V6
Scope of delivery
- JUBU high-strength aluminium water pump pulley
- Thermostat (two variants to choose from depending on the desired usage: "Road & Track" or "Ultimate Race" - please choose via "options")
Options
- Desired variant
- Variant 1: "Road & Track" - thermostat opens at 76°C, ideal for sporty driving on roads with infrequent trackday fun, but also for street use in regions with moderate/cold climate
- Variant 2: "Ultimate Race" - thermostat opens at 69°C, ideal for hard trackdays and/or for street use in regions with very warm climate and high outside temperatures; limited suitability for slow street cruising use and/or in regions with moderate/cold climate
NOTE: When choosing the "Ultimate Race" variant and smooth cruising on roads at low outside temperatures, the warning lamp "low water temperature" may sometimes light up (because the water temperatures get really low if there is no load applied and the outside temperature is cold).
