piston exchange?

[992GNTme]

Does anybody know if there is any different stock mits. or dodge piston of the same bore with lower compression ratio? I would like to change mine on my 420a turbo without buying je or cp or wiesco. I am use to hondas where you can change almost anything out on all b-series so i just thought i would ask some of you guys. Thanks,chris.

You're going to get a better and quicker response by posting this question in the 420a section. The 420a bolt-on forum allows new members to post in it.

If you are trying to find an answer to a question, odds are someone has already asked it on this site. There is a ton of information here. You can usually do a pretty vague search to find answers to any question. I just typed in 420a pistons and that was one of the 6 threads that came up. While the other 5 were irrelevant, that one showed to be very useful Just a little education.

Hi , thanks for the info but that still doesn't answer my question fully.
Does anybody know what the compression ratio on the sohc neon 420a is? It happens to have the same 87.5mm bore. Thanks again, chris.

And you didn't take my advice. Search 420a compression, 6th one down, post 2.

To save time,
A588

The A588 is the SOHC version. Output is 132 hp (98 kW) SAE (98 kW) at 5600 rpm with 130 ft·lbf (177 N·m) of torque at 4600 rpm. It has an aluminum SOHC cylinder head. It uses a reinforced plastic intake manifold (although a few of the 1995 & 1996 engines received an aluminum intake manifold due to a shortage of the plastic parts). They were painted black, but it's easy to see the casting marks and prints on the manifold. The aluminum version is much prized among enthusiasts as it's easy to port and polish for increased flow characteristics.

Applications:

* Dodge Neon/Plymouth Neon (1995-2005)
* Dodge Stratus (1995-2000)
* Plymouth Breeze (1996-2000)

Specifications

* Compression Ratio: 9.8:1
* Camshaft Configuration: SOHC
* Power: 132 hp (98 kW) @ 5600 rpm
* Torque: 130 ft·lbf (180 N·m) @ 4600 rpm


D4RE

The DOHC D4RE 2.0 produces 150 hp (110 kW) SAE at 6500 rpm with 130 ft·lbf (180 N·m) of torque at 4800 rpm. It has a cast iron engine block and aluminum DOHC cylinder head. It uses SFI fuel injection, has 4 valves per cylinder with roller rocker arms and features fracture-split forged powder metal connecting rods, a one-piece cast camshaft, and an aluminum intake manifold.

The version used in the Chrysler PT Cruiser and Dodge Neon features a cylinder head with the intake ports facing the front of the vehicle, like the SOHC A588. Versions (420A) used in the dodge-designed chassis, such as the Dodge Avenger and Mitsubishi Eclipse, have the intake ports facing the rear of the vehicle. Most other specifications are identical, however, and even some head components (such as the rocker cover) are compatible.

Applications:

* Chrysler PT Cruiser (non-US)
* Dodge Avenger/Chrysler Sebring (1995-1999)
* Dodge Neon/Plymouth Neon (1995-1999)
* Mitsubishi Eclipse/Eagle Talon (second generation, 1995-1999)

Specifications

* Compression Ratio: 9.6:1
* Camshaft Configuration: DOHC
* Displacement: 1996 cc (121.8 CID)
* Power: 140 hp (100 kW) @ 6000 rpm
* Torque: 130 ft·lbf (180 N·m) @ 4800 rpm


FYI the SOHC 420a does not exist. That model motor was not labeled with the 420a engine code like it's DOHC couterpart.
