Review SU Mg Midget Austin Healey Sprite Carburetor Set #auc870 fits HS2 1966–1974

The SU AUC870 Carburetor Set is a highly desirable upgrade for any Austin-Healey Sprite or Midget model from the years 1966 to 1974. These carburetors are recognized for their exceptional performance and reliability, making them a favorite among enthusiasts and collectors.

The SU AUC870 Carburetor Set comprises four individually boxed carburetors, all featuring the iconic SU logo emblazoned on the side. Each carburetor benefits from a number of enhancements compared to the original specifications of the Sprite and Midget's standard SU carburetors. The primary difference lies in the incorporation of the HS2 system, which offers several improvements.

The HS2 system introduces a number of refinements to the Idle Jet, to provide much smoother idle characteristics than the standard carburetors. A larger main jet and throttle shaft are included in the upgrade, which enable better midrange torque and improved throttle response. In addition, an improved throttle pump and accelerator pump mean that the engine benefits from better fuel delivery under all conditions, increasing overall power and efficiency.

Another significant advantage of the SU AUC870 Carburetor Set is that they are easily adaptable for use with various fuel systems, such as fuel injection or electronic ignition. This flexibility makes the upgrade a popular choice for Austin-Healey Sprites and Midgets that have undergone modification or customization work.

The construction of these carburetors is robust and of high quality, considering their classic design. Each carburetor is made from die-cast aluminum, which ensures strength and longevity, while the professional finish adds an attractive and polished appearance to the engine bay. Furthermore, the SU AUC870 Carburetor Set comes complete with a comprehensive instruction manual, providing clear and easy-to-follow guidelines for installation.

Overall, the SU AUC870 Carburetor Set is an excellent investment for any Austin-Healey Sprite or Midget owner who desires enhanced engine performance, improved fuel economy, and an authentic, high-performance upgrade that adds value and enjoyment to their classic vehicle. With their blend of history, technology, and desirability, these carburetors are a true testament to the enduring passion for the iconic Austin-Healey models.

Pros and Cons of Buying a SU Carburetor Set for a 1966-1974 Austin-Healey Sprite

b. Performance: SU carburetors have a reputation for providing excellent performance, particularly in classic cars like the Austin-Healey Sprite, as they offer good response and can handle a variety of driving conditions.

c. Availability: SU carburetors are widely available and can be procured from various online stores or specialists, which makes it easier for enthusiasts to restore their vehicles or upgrade their performance.

a. Complexity: SU carburetors can be more complex to install and maintain as compared to modern fuel injection systems. This may require specialized knowledge and tools, which could result in additional costs and time.

b. Cost: SU carburetors are generally more expensive than their modern counterparts. Additionally, the cost of specialized tools, fuel mixtures, and dyno tuning to optimize carburetor performance can add up.

c. Fuelling Issues: SU carburetors might not provide consistent fueling, especially under hard acceleration or low engine speeds, which may give rise to conditions like stalling or poor overall performance.

The decision to buy an SU carburetor set for a 1966-1974 Austin-Healey Sprite lies in a balance between maintaining originality and performance versus the additional complexity, cost, and potential fuelling issues.

If you value originality, performance, and the 'classic' driving experience, and you're committed to investing the time and resources required to install, maintain, and tune an SU carburetor setup, it could be a worthwhile investment for your Austin-Healey Sprite. However, if you prefer a simpler alternative that's more cost-effective and requires less maintenance, you might consider exploring modern fuel injection systems that offer reliable performance and ease of use. Ultimately, the choice depends on your preferences, budget, and technical expertise.
