The block uses a bedplate featuring a perimeter wall with transverse webbings for durability and quiet operation at high engine speeds.
The pistons are attached to fracture-split forged, powdered metal connecting rods using semi-floating press-fit pins.
The second feature was internal in nature - the crankshaft main bearings were keyed into the bedplate on the right rear of each transverse web.
The third feature would be a slightly bigger camshaft profile that was changed on 1996 and up SOHC vehicles due to a rough idle when the air conditioning was on.
2002 and earlier engines featured a one-piece cast nodular iron crankshaft with counterweights present on either side of each crank pin.
Chrysler Corporation used several different designs of composite material head gaskets in an attempt to solve this problem.
The shorter runners, open from 4800 rpm to redline at wide-open throttle, also provide a tuned resonance effect due to their length.
The shorter runners are also opened at wide-open throttle below 3000 rpm to provide an intake path to each cylinder that is as free-flowing as possible.
It uses Sequential fuel injection, has 4 valves per cylinder with roller rocker arms and features fracture-split forged powder metal connecting rods, a one-piece cast camshafts, and an aluminum intake manifold.
The version used in the PT Cruiser (non-US) and Dodge Neon features a cylinder head with the intake ports facing the front of the vehicle, like the SOHC A588.
Applications: Specifications: The 150 hp (112 kW) Naturally Aspirated (N/A) version was used in Chrysler's JA, JX, and JR platform cars from 1995 to 2006 along with the Jeep Liberty from 2002 to 2005 and the Dodge Caravan and Plymouth Voyager from 1996 to 2000.
The turbocharged EDV/EDT was initially developed for the PT Cruiser GT as a way to add power, and is similar to the regular EDZ.
As the PT Cruiser was based on the Neon platform, PVO engineers were able to take the EDV/EDT and make it work with minor non-costly changes for the SRT-4.
The SRT-4 has a cast-aluminum 8-row Valeo intercooler mounted in the front, and the reverse-rotation Mitsubishi TD04LR-16Gk turbocharger has a 6 cm2 (1 sq in) turbine inlet.
The Turbo-Lite option for the PT Cruiser offered a de-tuned EDV/EDT that could run on regular 87 octane (R+M/2) gas, making 180 hp (134 kW) SAE at 5300 rpm.
