Phase ZR310 power approx. +89Hp/+55Nm Elise S (2ZR)

Performance phase ZR310

• Performance data ZR310: approx. 309 hp / 305 Nm
• Performance data stock: approx 220 hp / 250 Nm (factory specifications 220)

After our well-known and successful performance phases ZR265 and ZR285, we are now adding the new ZR310 variant.

In order to give the Elise S / Sport 220 / Cup 250 a little more performance, we have developed this performance phase. The 1.8 S (2ZR engine) differs from the predecessor 1.8 SC (2ZZ engine) by a completely new engine generation and a supercharger that is now equipped with a water-cooled intercooler (previously completely without LLK or, in the case of the Exige S with air/air cooler). Thus, the problem of weak intercooling of the older models is significantly reduced. However, the shortcoming of the current 1.8 S lies more in the area of exhaust system and tuning of the engine management. The original exhaust manifold is very small and the pipe lengths are not optimal. That's why we use a 4:1 stainless steel exhaust manifold with optimized pipe lengths and a 200-cell HJS sports catalytic converter. The result is a nice sporty sound without being obtrusive and an improvement in performance and torque curve. To optimize the intake, we use a KT Sport airbox. Compared to the ZR285 phase, which already uses a freely programmable engine control unit, the ZR310 phase has an additional set of sports camshafts. Unfortunately, the 2ZR engine with 285hp already reaches its stability limit, so it is pointless to build the ZR310 variant on this relatively weak basis. Especially for racing and the Cup Elise models used there, we have developed steel connecting rods and forged pistons for the ZR310. These components are not just a replica of the serial parts in better material, here the design and dimensions have also been completely changed to meet the increased requirements. The kit includes the complete conversion with engine removal, disassembly, machining, assembly, retraction and individual adjustment on the test bench. Please note that your original engine will be reused as a base, so it must be suitable for conversion in terms of condition and mileage

Key Benefits:

• Additional extra power and torque
• Optimal upgrade of existing ZR285 vehicles
• more torque (+55 Nm) and power (+89 Hp) to the production vehicle (220)
• Very individual tuning of the control unit and the "Sport" function thanks to the use of the freely programmable control unit
• optimized steel connecting rods ZR310
• Forged piston ZR310

Service phase ZR310 consisting of:

• KT-Sportairbox
• Modified pulleys, loader ratio and ribbed belts
• Stainless steel manifolds with optimized tube lengths (4:1)
• 200-Zellen-Sport Catalytic Converter HJS
• Optimized HKS spark plugs
• EMU Black freely programmable control unit with broadband lambda control,
• Individual tuning to ZR310 (ignition, injection maps, throttle valves, characteristic curve and camshaft phase adjustment)
• KT Sport Camshaft Set ZR310
• KT steel connecting rods ZR310 in optimized design
• KT Forged Piston ZR310

We strongly recommend the use of our intercooling system, especially when used in harsh driving conditions and racetrack use! The use of a sports rear silencer is mandatory! Please note that not all rear silencers available on the market will fit with our system! If you have any questions in this regard, please do not hesitate to contact us.
