Do you ever think your Honda engine could perform a little bit better than it currently does? Well, you're probably not alone in this case. Honda fans seek stronger performance from their vehicles and find their solution in the renowned LS VTEC conversion kit.
Now, before we dive deep into this topic, let's get one thing straight: The project is far beyond a basic backyard repair. This is serious engine surgery. Our project aims to connect the performance benefits of Honda B-series heads to the power foundation of B18 or B20 blocks.
VTEC is Honda's variable valve technology that is used to change the amount of valve lift and valve duration in the engine. By altering valve lift and duration, you can influence how much air the engine receives and can thus influence power. The more air you put in an engine, with more fuel, the more horsepower you make! And everyone loves horsepower. (How VTEC Works - A Simple Explanation)
The system takes the best features from both systems and combines them to work effectively. You upgrade your engine by switching out its cylinder head for a VTEC version.
VTEC basically meansVariable Valve Timing and Lift Electronic Control. It's a brilliant engine system that allows a switch between two camshaft profiles:
Low-RPM profile: Focuses on engine torque and fuel efficiency.
High-RPM profile: Unleashes maximum horsepower by optimizing airflow.
Because of this, the engine performs perfectly through all speed ranges to produce both powerful low-end grunt and exhilarating high-rpm scream.
Significant Power Gains: Expect a substantial boost in both horsepower and torque across the entire RPM range.
Improved Fuel Efficiency (in some cases): While not the primary goal, the low-RPM efficiency of VTEC can actually improve fuel economy in certain driving conditions.
Enhanced Driving Experience: The responsiveness and character of a VTEC engine are truly something special.

What are the disadvantages of a VTEC engine?
While a VTEC Engine generally tends to be more reliable, VTEC engines could potentially be more complex to maintain and harder to repair due to their intricate design.
How does LS VTEC work?
The LS VTEC system dynamically selects between two camshaft profiles to achieve optimal power delivery throughout the RPM spectrum.
How reliable is a VTEC engine?
With proper maintenance, and of course good care; your VTEC engines can be incredibly reliable and long-lasting.
How long does a VTEC engine last?
A VTEC engine's durability depends on regular maintenance work as well as how you drive and how well it stays in good shape. These engines can achieve more than 100,000 miles if you maintain them correctly.
Building an LS/VTEC engine is an exhilarating challenge for passionate Honda enthusiasts!
