Toyota Engines
The Toyota engines are fitted to the later Elise S (06 on) / 111R (04 on) / Elise R / Elise SC and all Series 2 Exiges.
They are generally reliable and pretty robust, however the 2ZZ-FE (Elise R / 111R / Elise SC / Exige) engine has been known to have problems with oil starvation at high corner speeds (a retro fit baffled sump will cure this), camshaft failure (excess lobe wear) and clutch failure.
The 1ZZ-FE has only been fitted to the Elise since 2006 and there have been no known problem areas as yet.
The Toyota engine and subframe weighs more than the equivalent K series which obviously affects the performance and C02 figures are much higher.

Toyota acts over drink problem
Japanese giant Toyota’s reputation for rock-solid reliability has taken a knock, as owners have been reporting problems with its hi-tech VVT-i petrol and Lexus diesel powerplants.
The 1.8-litre VVT-i engine is found in models across the line-up, but can suffer from excessive oil burning from as few as 50,000-60,000 miles, according to main dealers. The problem is being blamed on the piston ring design, and Toyota says that any unit consuming more than one litre of oil every 1,000 miles will be looked at and, full service history permitting, rectified.
The manufacturer reckons the problem is specific to the driving conditions in this country. It says they affect what is known as the engine’s ‘fifth injector’, which controls the vehicle’s emissions. Apparently, only a handful of cars have developed difficulties so far.

There is a strong rumour that a group of elite Selocers are developing a 120BHP Rover K-Series upgrade for the 111R and S2 Exige to combat the Toyota's drink problem.
