1. Weber 32/36 DGV Manual Choke Carburetor: Top Pick – Best Overall
The Weber 32/36 DGV is a popular upgrade for the 22R, known for improving throttle response and overall drivability. In our evaluation, its progressive linkage allows smooth power delivery, and the manual choke gives reliable cold starts. Based on owner feedback, it often outperforms stock carburetors in both power and fuel efficiency.
However, installation typically requires an adapter plate (not included) and some tuning. This carburetor is not ideal for those wanting a simple bolt-on replacement without adjustments. Skip this if you prefer an automatic choke or a truly plug-and-play solution.
- Progressive linkage provides smooth transition from idle to full throttle
- Manual choke offers precise control in cold starts
- Widely supported aftermarket with many adapter kits available
Pros: Excellent throttle response and fuel atomization; Simple design easy to rebuild and tune
Cons: Manual choke requires driver adjustment; May need adapter plate for 22R intake manifold
2. Weber 38/38 DGAS Electric Choke Carburetor: Runner Up – Best Performance
The Weber 38/38 DGAS is a performance-oriented carburetor that shines on modified 22R engines with headers and camshafts. Our research shows it flows more air than the 32/36, making it suitable for high-output builds. Owner feedback highlights its strong top-end pull.
But for a stock 22R, this carburetor may cause drivability issues due to excessive fuel delivery. It demands careful jetting and tuning, which may frustrate beginners. Skip this if you have a mostly stock engine or prioritize fuel economy over power.
- Synchronous linkage delivers equal airflow to both barrels
- Electric choke provides automatic warm-up enrichment
- Larger venturi for increased top-end power
Pros: Significant horsepower gains on modified 22R engines; Convenient electric choke eliminates manual adjustments
Cons: Can be overly rich for stock engines, requiring jetting changes; Higher fuel consumption in daily driving
3. Aisan Original Equipment Replacement Carburetor: Best OEM Replacement
For those seeking a straightforward replacement, the Aisan OEM carburetor is the most reliable choice. We compared its specifications to the factory unit and found identical calibration. Owner feedback confirms its hassle-free installation and consistent performance.
However, it offers no performance gains and may cost more than aftermarket alternatives. This carburetor is best for those who want to restore factory operation without modifications. Skip it if you are looking for better throttle response or fuel economy.
- Direct bolt-on replacement for stock 22R engines
- Electric choke for automatic operation
- Uses Toyota factory calibration for reliability
Pros: Exact fit with no adapter or tuning required; Proven long-term durability from OEM supplier
Cons: No performance improvement over original carburetor; Often more expensive than aftermarket options
4. Holley 5200 Progressive 2-Barrel Carburetor: Best Value Upgrade
The Holley 5200 is a budget-friendly alternative to the Weber 32/36, offering similar progressive linkage. Our evaluation of owner feedback indicates that when tuned properly, it provides a good balance of performance and fuel economy for the price.
However, some units arrive with imperfections, and the included gaskets may leak. It demands more initial setup than pricier options. This carburetor is suitable for DIY enthusiasts on a budget but not for those wanting a reliable out-of-box experience.
- Progressive design improves fuel efficiency over stock
- Manual choke for driver control
- Affordable upgrade path for budget-conscious owners
Pros: Noticeable improvement in throttle response; Lower cost compared to Weber counterparts
Cons: Quality control can be inconsistent; Requires adapter and tuning out of the box
5. Spectre Performance 2-Barrel Carburetor: Best for Off-Road
The Spectre Performance carburetor is designed with off-road enthusiasts in mind, featuring calibration that enhances low-end torque. Based on owner feedback, it performs well in mud, rocks, and steep inclines, resisting stalling better than stock.
However, this carburetor lacks refinement for street driving, with a tendency to run rich at idle and poor fuel economy. Skip this if your 22R is primarily a daily driver. It is best for dedicated off-road or trail rigs.
- Calibrated for off-road use with improved low-end torque
- Manual choke for reliability in remote areas
- Reinforced throttle shaft for durability
Pros: Better throttle response on rough terrain; Sturdy construction withstands vibration
Cons: Not ideal for daily driving or highway use; Manual choke can be inconvenient for street use
6. Redline Weber 32/36 DGV Conversion Kit: Best Complete Kit
The Redline Weber conversion kit simplifies upgrading to a Weber 32/36 DGV by including the adapter plate, air cleaner, and linkage. Our research shows it is pre-jetted for the 22R, which reduces the tuning required. Owner feedback praises the clear instructions and ease of installation.
However, some users report that the included air cleaner may not fit all hood clearances, and the gaskets can be subpar. This kit is ideal for those who want a complete solution but may not suit those with unique modifications. Skip it if you already have adapter parts or prefer a different air cleaner setup.
- Complete bolt-on kit with all necessary components
- Pre-jetted for 22R, reducing tuning effort
- Includes detailed instructions for installation
Pros: No need to source additional parts; Smooth installation process for DIYers
Cons: Kit components may have fitment variances; Higher upfront cost than buying carburetor alone
7. Proform 2-Barrel Carburetor with Electric Choke: Best for Tuning Flexibility
The Proform carburetor offers tuning flexibility with adjustable mixture screws, appealing to those who like to dial in their setup. In our evaluation, it has the potential to perform well when properly adjusted, but out of the box it often runs lean or rich.
However, durability is a concern, with some owners experiencing throttle shaft wear or leaks after short use. This carburetor is best for experienced tuners willing to invest time. Skip it if you want a reliable daily driver carburetor without ongoing adjustments.
- Adjustable air/fuel mixture screws for fine-tuning
- Electric choke for automatic operation
- Compatible with most 22R intake manifolds
Pros: Allows customization for different driving conditions; Electric choke adds convenience
Cons: Quality control issues reported by some owners; May require significant tuning to run correctly
Frequently Asked Questions
Will a Weber carburetor bolt directly onto my 22R intake manifold?
Most Weber carburetors require an adapter plate to fit the 22R’s intake manifold. The adapter is usually sold separately, though some kits include it. Always check compatibility before purchasing.
Do I need to change my distributor or ignition when upgrading the carburetor?
Not necessarily, but a carburetor upgrade can expose weaknesses in the ignition system. For best results, ensure your spark plugs, wires, and distributor are in good condition. Some owners upgrade to a electronic ignition for improved reliability.
Which carburetor is best for fuel economy on a stock 22R?
The Weber 32/36 DGV with progressive linkage often improves fuel economy over the stock Aisan carburetor when tuned correctly. The Aisan OEM replacement also delivers factory fuel economy. Avoid larger carburetors like the Weber 38/38 for daily driving if fuel economy is a priority.
How difficult is it to tune a Weber carburetor on a 22R?
Tuning a Weber is moderately easy with basic tools. You’ll need to adjust idle mixture, idle speed, and possibly jetting. There are many online guides and videos specific to the 22R. Beginners can do it with patience, but some prefer a professional tune.
Can I use a carburetor from a different Toyota engine on my 22R?
It is not recommended, as the 22R has specific intake manifold bolt patterns and vacuum requirements. Using a carburetor from another engine may require extensive modifications and could cause drivability issues. Stick to carburetors designed for the 22R or universal models with adapter kits.
Our Verdict
After thorough research and comparison, the Weber 32/36 DGV Manual Choke Carburetor stands out as the top pick for its balance of performance, reliability, and aftermarket support. For those seeking maximum power, the Weber 38/38 DGAS is the runner up, but it requires a modified engine and careful tuning.
