SharkWerks full 3.9L engine conversion for the venerable Porsche 997 GT3 motor has been tried and tested since 2009 on cars all over the planet. Tuned in the extreme heat of Arizona on the road and on a Mustang Dyno the 3.9L engine conversion brings up the horsepower from a factory 3.6’s 385rwhp (415hp) to 458rwhp (502hp) and from 274rwtq (300tq) to 326rwtq (355tq). The EVOMSit software (featuring IST and SP) is calibrated for either 91 or 93 octane levels. With more than fifty foot pounds of torque made available in the lower rpm range as well as an additional 70plus HP in the higher RPMS the character of the motor is amplified and even extended by an additional 400rpms. Utilizing our light-weight Piston kit we are also able to improve upon the already-quick throttle response and revs to an even more lively level.

This isn’t your average gloss meter. Utilized in our internal testing, this $5000 apparatus allows us to scientifically evaluate various detailing methods and products. This provides tangible data, instead of simply stating that one process yields superior results. Rhopoint IQ Gloss, Haze & DOI Meter quantifies surface quality problems that are invisible to a standard glossmeter and profiles how light is reflected from a surface.

We prefer using Dr Touch up paint due to its superior color matching consistency and the added advantage of being reversible within the initial 15 minutes. Moreover, we appreciate the provision of a specific color as opposed to a generic commercial color kit. It may cost a bit more, but we are convinced that it sets us apart from the competition.

Disassembly for cleaning paint protection film PPF installation

Taking apart components and panels greatly enhances the effectiveness and neatness of paint protection film installation. The debris lodged within panels becomes visible, and we attain superior access during the film placement. Indeed, this approach requires more time and effort; however, it typically yields a more satisfactory outcome compared to the standard installation procedure.

I trust less than a handful of people with my vehicles and “particular” is an understatement for me when it comes to anything with my cars. There is no one I trust more to take care of my cars and keep them pristine than Carzwerk. Post track day weekend, car goes to Carzwerk and you would never be able to tell the cars were tracked. My 15 year old race car looks better than a brand new showroom car and I would literally eat off of it. Brand new car we bought – it goes to Carzwerk first (before we even get to drive it!). Truth is, Carzwerk understands how anal I am when it comes to perfection with my cars and he works with me to achieve that process. He doesn’t sell me crap, he doesn’t push crap on me – he makes sure that I have all the data to make the most informed decision that I can. He works with me and often exceeds my anal retentiveness. Thank you Carzwerk!

Carzwerk Story

For Porsche 911 GT3 enthusiasts seeking to elevate their driving experience to a whole new level, the SharkWerks 997.1 GT3 3.9 Engine Upgrade is a tantalizing proposition. Born from the minds of performance aficionados at SharkWerks, this modification package takes the already impressive Porsche 997.1 GT3 to new heights, offering more power, enhanced performance, and an unforgettable driving experience. In this blog post, we’ll dive into the details of this remarkable engine upgrade and what it means for Porsche enthusiasts.

SharkWerks: A Legacy of Performance

Before delving into the specifics of the engine upgrade, it’s essential to understand the reputation of SharkWerks. As a premier Porsche tuning shop based in Northern California, they have earned a name for themselves by crafting bespoke modifications for Porsche vehicles, particularly the GT3 models. Their expertise, passion, and attention to detail have made them a trusted name in the Porsche tuning community.

The Heart of the Beast

At the core of the SharkWerks 997.1 GT3 3.9 Engine Upgrade is, of course, the engine. Starting with the stock 3.6-liter naturally aspirated flat-six engine, SharkWerks embarks on a meticulous transformation. The engine is bored out to increase displacement, resulting in a larger 3.9-liter powerplant. This fundamental change lays the foundation for a significant increase in power and torque.

Performance Enhancement

The results of this engine upgrade are nothing short of astonishing. The Porsche 997.1 GT3, in its standard form, already delivers an impressive 415 horsepower. However, the SharkWerks 3.9-liter upgrade pushes that figure even higher, typically achieving over 500 horsepower. This increase in power translates to a remarkable boost in performance, reducing the 0 to 60 mph time and significantly improving overall acceleration.

An additional advantage of the SharkWerks 3.9 Engine Upgrade is the enhanced throttle response and mid-range torque. This means that not only do you get more power at the top end, but the engine also delivers a stronger, more accessible surge of power in the mid-range RPMs, making the car feel more lively and responsive in everyday driving.

The Signature Sound

Porsche enthusiasts know that the auditory experience is a critical aspect of owning and driving a Porsche GT3. The SharkWerks 997.1 GT3 3.9 Engine Upgrade ensures that the car’s sound matches its performance. The upgraded engine emits a distinctive and exhilarating soundtrack, complete with a thrilling flat-six wail that becomes even more pronounced as the RPMs climb.


The SharkWerks 997.1 GT3 3.9 Engine Upgrade is a testament to the commitment of SharkWerks to push the boundaries of Porsche performance. It transforms an already exceptional sports car into a true powerhouse, offering more power, better acceleration, and a spine-tingling exhaust note.

For Porsche 997.1 GT3 owners who seek the ultimate driving experience, this upgrade is a compelling choice. It combines the precision engineering of Porsche with the expertise of SharkWerks, resulting in a car that not only goes faster but also provides an unmatched level of excitement every time you get behind the wheel. If you’re a Porsche enthusiast, the SharkWerks 997.1 GT3 3.9 Engine Upgrade is an opportunity to turn a great car into a true masterpiece of performance and sound.
