Are there any differences in the 200/210 159 engines to the 156 20v's?!
From the 159 launch press release
"Derived from the familiar, 2.4 JTD five cylinder 10 valve common rail powerplant, several changes have been made to the latest version of this 20 valve turbodiesel to boost performance and engine torque at low speeds whilst returning impressive fuel consumption figures. The common rail system includes two new control strategies for automatically calibrating and balancing the diesel injection, to both lower noise and reduce vibration, whilst the direct injection pressure has been increased from 1400 to 1600 bar.
The engine also includes a number of new components; a cylinder head with small stem valves to boost inlet air quantity, fractured steel con rods of a new, stress resistant design, a new inlet manifold fitted with a throttle valve at one of the two inlet ports to control air turbulence, a new, high efficiency intercooler, and a throttle valve to prevent shaking if the engine is stalled.
The electronic EGR exhaust gas cooling system has also been modified; the lubricating circuit has a new oil pump and an external air/oil heat exchanger to cool the oil, whilst the water pump on the cooling circuit is also new.
Turboboost is provided by a KKK 2080 turbocharger with a variable geometry turbine that improves power delivery and also generates very high torque at low engine speeds; 90% of the impressive 295lb.ft peak torque is available from between just 1750 and 3500rpm. Mated to an F40 6-speed manual gearbox, this allows the Alfa 2.4 JTD MultiJet to accelerate from 0-62mph in only 8.4 seconds, whilst returning a remarkable fuel consumption of over 41mpg in the official combined cycle."
