2003 was the last year of the 7.3L Powerstroke engine being used in Ford Superduty Trucks. Stricter emissions standards resulted in a need for lower emissions and competing manufacturers were designing trucks with similar or better performance capabilities.
The Ford 7.3L Powerstroke engine was produced from 1994 to 2004. Over 2 million of the 7.3L Powerstroke engines were manufactured over the decade-long production life of the engine.
Does Ford still make 7.3 Powerstroke?
Ford’s 7.3-liter truck engine is back, and this time it’s a gas. This is deliberate. Ford could’ve designed its new big-bore gasoline truck engine to any size it wanted, but it chose to give each cylinder a 4.22-inch bore and a 3.98-inch stroke.
Driving the truck empty is a comfortable experience. Starting and stopping are smooth, and the ride is, as expected, a little rough. Over the 58.8-mile course I used 3.954 gallons of gas, which gave me a calculated 14.87 mpg. The computer read 14.9 mpg, which is exactly the same as our calculated number when rounded.
What was the last year of 7.3 Powerstroke? – Related Questions
Is 6.0 or 7.3 engine better?
From a reliability, durability or simplicity standpoint, the 7.3L is hands down the winner. When it comes to horsepower, drivability and meeting modern day emissions standards, the 6.0L has it beat. Ultimately, both engines have their pros and cons.
Why did Ford stop making the 7.3 Power Stroke?
The 7.3 L DI Power Stroke was in production until the first quarter of model year 2003, when it was replaced by the 6.0 L because of its inability to meet California noise regulations, not the commonly believed emissions standards.
Is the 7.3 diesel a good engine?
According to TheDrivingLine.com the 7.3 liter Diesel engine is the most reliable Powerstroke of them all. One reason is that it was in production before certain regulations were put in place for diesel engines. Therefore, the absence of emissions controls on the engine makes it far less complicated.
Which Ford diesel engine is the best?
In terms of reliability, the 7.3L Power Stroke is still the best diesel engine in 2021. Since it was manufactured, it has retained that worth. The Ford’s 7.3L Powerstroke’s engine block and internal compositions were over-engineered and over-built for the capacity of the truck’s power output.
The birth of the Power Stroke: the legendary ‘7.3’ years
As a result, in 1994, International Harvester (by now renamed Navistar International) began producing what it called the T444E engine. You might know it a little bit better by the name that Ford gave it: the 7.3-litre Power Stroke.

2003 to 2007 Powerstroke 6.0L Problems:
2011 to 2014 Powerstroke 6.7L Problems:
How many miles does a 7.3 last?
Robust, iron parts, conservative power and low engine speed are the key ingredients for any diesel engine lasting forever—and if a 7.3L has gone unmodified yet been well maintained its entire life, 400,000 to 500,000 miles is virtually guaranteed.
What year did the 7.3 Get a turbo?
1993 saw the debut of the 7.3L with a turbocharger. The engine’s internal parts were also upgraded to withstand the turbo boost pressure. Despite the turbo addition, this engine didn’t get much of a power or torque boost.
What’s the difference between the 7.3 IDI and 7.3 Powerstroke?
The 7.3 IDI is not the same as the 7.3 Powerstroke engine. Despite sharing displacement designations, these engines have numerous differences. The 7.3 Powerstroke is computer-controlled, whereas the 7.3 IDI relies entirely on mechanical parts.

How do you get 500hp out of a 7.3 Powerstroke?
Aside from adding a chip, a considerable up-sizing of the fuel injectors is mandatory to get any kind of measurable horsepower out of a 7.3L Power Stroke. For us, the only option is to upgrade to a set of hybrid injectors, and specifically the 238cc version for 500hp goals.
How do you make a 7.3 have more power?
One of the main ways to increase power is to get more air into the engine as efficiently as possible. However, that air also has to exit the engine efficiently. That’s where 7.3L Power Stroke exhaust mods come into play. An exhaust system will reduce back-pressure which helps increase power and reduce turbo spool time.
What does a wicked wheel do for a 7.3 Powerstroke?
This wheel with performance modifications controls turbo surge problems associated with the stock turbo wheel. It fits the GTP38 stock turbocharger. The anti-surge wheel is a direct fit replacement and will enhance turbo performance when towing or adding horsepower with performance.
