Oil Pan Face-Off: Pt Cruiser Vs Srt4

The PT Cruiser and the SRT-4 share the same engine block, but there are some key differences between the two. The SRT-4 features piston oil squirters, while the PT Cruiser does not. The SRT-4 also has a unique intake manifold and a higher-volume oil pump to accommodate the turbocharger and piston oil squirters. The PT Cruiser's oil pan is likely smaller than the SRT-4's due to the latter's additional oil-related features.

PT Cruiser and SRT-4 engines have different intake manifolds

The PT Cruiser and SRT-4 engines have different intake manifolds. The PT Cruiser's intake manifold can be purchased from Mopar, while the SRT-4's can be purchased from JMF. The PT Cruiser's intake manifold is made from the highest-grade materials, ensuring dependable and long-lasting service.

Upgrading the PT Cruiser's intake manifold to the composite manifold that comes stock on the '05+ models is the best option for improved performance. This composite manifold has smooth runners and a diverter that addresses a lean condition in the #3 cylinder. However, it is challenging to find aftermarket or performance intake manifolds for the PT Cruiser, especially for the 2003 GT model.

The SRT-4 engine, on the other hand, has a long block identical to the PT GT engine, but with a different intake manifold and wiring harness. The SRT-4 engine harness is different from the PT Cruiser's underhood and engine harness, and it is not easily spliced.

In summary, while both the PT Cruiser and SRT-4 engines have distinct intake manifolds, there are also differences in other components, such as the wiring harness and block design, that set these engines apart.

SRT-4 has lower compression pistons

The stock compression ratio of the SRT-4 engine is 8.0:1, which is considered low compression. This is the same compression ratio as the PT Cruiser GT engine. When building an engine that will make 400+ horsepower, it is recommended to use low compression pistons in the 8.0:1 to 8.5:1 range. This is because higher compression ratios increase the chance of engine knock or detonation, which can damage the motor. Additionally, when increasing boost pressure beyond the stock level, it is recommended to get a custom tune to be safe.

Stock SRT-4 pistons and rods can handle up to around 400 horsepower, but for longevity, it is recommended to upgrade the pistons and rods when targeting 400+ horsepower. The stock SRT-4 bottom end has been dyno-proven to handle over 500 horsepower; however, shortly after that test, the engine blew and put a rod through the block. It is important to note that the tune plays a significant role in the engine's reliability when targeting higher horsepower levels.

When building an engine, it is essential to consider the intended power level and choose the appropriate pistons and rods. For example, for an engine targeting 500+ horsepower, Pauter billet rods and custom JE pistons can be a good choice. Additionally, it is recommended to balance the rotating assembly, which includes the pistons and rods, to ensure smooth operation.

In summary, the SRT-4 engine features low-compression pistons, typically in the 8.0:1 to 8.5:1 range, which is a common choice for engines making 400+ horsepower. Upgrading the pistons and rods is recommended for higher horsepower builds to ensure reliability and longevity. Proper tuning and attention to boost pressure are also critical factors in the engine's performance and longevity.

SRT-4 has piston oil squirters, PT Cruiser doesn't

The SRT-4 engine has piston oil squirters, while the PT Cruiser engine does not. This feature helps to cool and lubricate the pistons, improving performance and longevity. The SRT-4's piston oil squirters are a significant advantage over the PT Cruiser, especially when it comes to high-performance applications or extended periods of heavy load.

The SRT-4's piston oil squirters are a part of its advanced lubrication system, which also includes an oil pan with a windage tray and an oil pump with improved capacity and pressure. These features work together to ensure that the engine's moving parts are adequately lubricated, even under extreme conditions.

In contrast, the PT Cruiser's engine does not have built-in piston oil squirters. This omission may be due to cost-saving measures or the fact that the PT Cruiser was not designed for high-performance applications. However, it is important to note that the PT Cruiser's engine still has adequate lubrication for its intended use.

For those seeking to modify their PT Cruiser for increased performance, adding piston oil squirters is a common upgrade. This modification can help improve the engine's performance and longevity, bringing it closer to the capabilities of the SRT-4. However, it is important to note that such modifications should only be performed by experienced professionals to ensure safety and reliability.

Overall, the presence of piston oil squirters in the SRT-4 engine highlights its performance-oriented design and attention to detail. This feature contributes to the engine's overall reliability and performance, making the SRT-4 a more robust and capable powerplant than the PT Cruiser's engine.

PT Cruiser GT has a different transmission to SRT-4

The PT Cruiser GT, also known as the GT Cruiser, is a high-output turbocharged hot hatch variant of the PT Cruiser. It was introduced as a 2003 model and has a different transmission to the SRT-4.

The PT Cruiser GT features a 4-speed automatic transmission with overdrive or a 5-speed Getrag manual transmission. The SRT-4, on the other hand, has a T850 transmission. The T850 transmission is not interchangeable with the transmission in the Neon (T350), indicating that it is different from the PT Cruiser's transmission.

The PT Cruiser GT's transmission allows for different driving experiences, with the manual transmission providing a sportier feel and the automatic transmission offering a more relaxed driving experience.

In addition to the transmission differences, the PT Cruiser GT and the SRT-4 have some other distinctions. The PT Cruiser GT has a different engine, with upgrades such as MOPAR Stage 1 and supporting turbo components. The exterior of the PT Cruiser GT also differs, featuring a body kit and chromed 17-inch wheels. The interior may also have unique features, such as a Boston Acoustics premium sound system in some models.

While both vehicles fall under the Chrysler brand, the PT Cruiser GT and the SRT-4 cater to different consumer needs and preferences, with the PT Cruiser GT offering a blend of performance, practicality, and style.

PT Cruiser and SRT-4 have different oil pumps

The PT Cruiser and SRT-4 have different oil pumps, and there are some significant differences in their engines. The PT Cruiser's oil pump is located within the engine bay, while the SRT-4's oil pump is positioned near the front of the vehicle.

The oil pump in the PT Cruiser is driven by the crankshaft and is responsible for circulating oil throughout the engine to lubricate and cool its components. It is a critical component of the engine and requires regular maintenance to ensure reliable performance.

On the other hand, the SRT-4's oil pump is designed to handle the higher performance demands of the vehicle. It is typically located near the front of the engine and is driven by the camshaft or a separate shaft connected to the crankshaft. This design allows for increased oil flow and pressure, which is necessary for the SRT-4's high-performance engine.

When it comes to oil pump maintenance and repairs, both vehicles have their own specific procedures. For the PT Cruiser, oil pump replacement can be a complex process, requiring the removal of several engine components and careful attention to timing and alignment. The SRT-4's oil pump replacement procedure may vary depending on the model year and specific engine configuration. However, it generally involves removing the front cover of the engine and accessing the oil pump drive components.

In terms of oil pump performance, the SRT-4's pump is designed to deliver higher oil flow rates and pressures to accommodate the engine's higher horsepower and RPM capabilities. The PT Cruiser's oil pump, while adequate for its intended application, may not be able to handle the demands of a high-performance engine. Therefore, it is important for owners and mechanics to use the correct oil pump for their specific vehicle to ensure optimal performance and longevity.
