2007 Shark Werks 3.9L 997 GT3 & Guard LSD

To be honest, we are typically a personal operation and it is very special when someone sends us their car, especially from another country.

The owner of this white 997 GT3 is a regular at the local tracks in Quebec, and for the past 30,000 KM, the car has been both a daily driver and weekend toy when weather permits. He's a longtime Porsche fan and has owned a 964 Carrera RS and others in the past, and his son is right behind him, having tracked several Porsches together over the years. He purchased the 997 GT3 because he wanted a proper track car that could be driven to the track, towing the gear/wheels all in one vehicle (notice the trailer hitch in the pictures below!)...

He found out about the 3.9L cars we had been building and decided it was time for some more power. The car was sent to us using Intercity Lines all the way from Quebec to begin its operation.

And once again, the lucky 3.9L transplant recipient is a white GT3. Yes, so many white cars!


The 3.9L upgrade is best explained with this video:


Disassembly begins:


Motor removed:




A regular track junkie, he asks us to rebuild his LSD with Guard:


With all of the parts ready, James continues to assemble motors into the night...

In the morning, we see progress:



The layers pile up:



In go ze custom SharkWerks/EVO cams, for more flow at the top-end of the RPM band and even more power with the extra displacement:


The cams are timed, which is a two man job. I was sick, so no photos, but here's a pic from a previous build:


On goes the cover:

And the accessories begin to take form:




The single mass lightweight flywheel takes 14 lbs off the rotating mass (down from 28 lbs) on a GT3 model:


And Cup Car clutch assembly:


The forementioned trailer hitch:


On go the 88mm SharkWerks Stainless Steel exhaust tips (with SharkWerks Bypass Exhaust, of course!):



And here she is, ready for a 200-mile breakin drive prior to her first oil change. Notice the scary dark clouds on the horizon:


The weather clears up a bit:


Two critical upgrades! After its breakin and first oil change, a SharkWerks license plate is added along with the coveted ($26,000) 3.9 badge:


The plate is temporary and will eventually be modified further to allow the trailer hitch to be cleanly installed.

The owner arrived at a local airport, flying straight from Quebec with his son. Their plan: drive the newly equipped 3.9L GT3 all the way back home from California. An incredible 3000 mile drive through North America, including Nevada, Salt Lake City, the midwest and the Great Lakes region.



Ready, set...


And off it goes!


It was a real pleasure meeting its owner and his son, and we're wishing him a fun trip home with great weather. We'll keep you posted on this car's progress at its local stomping ground and of course other 3.9L builds here at SharkWerks.
