This week we had a simple, understated silver GT3 show up from Southern California. The owner made the ~350 mile drive and dropped her off, then took a plane ride home to let us get to work. The requested upgrades were our bypass exhaust and EVOMSit software, but sometimes things can get a little crazy around here...

The car was put on the lift:


The ECU was read-out and EVOMSit tuning was installed:

Bumper and center/side muffler removed:


On goes the bypass:

In the background, a 997.2 GT3RS is being prepped for more upgrades..


A few more parts are removed from the GT3:


Something's missing here:


Ah, there's the transmission:


997 GT3RS lightweight flywheel, a great upgrade to help bring the car to life... easier revs, better 0-60 and a lot more fun to drive:




And guess what's next?

Well it's too soon for pictures, but the owner called us, luckily while the transmission was out, requesting a few more changes. The next round of upgrades will be the Shark Werks 3.9L Upgrade and various suspension bits. Stay tuned for updates!

We never know what cars might show up during a given week here, so when Alex or I pop into the back during the day, it's always fun to guess what colors we'll see. Yellow, white, orange, silver, black... green, of course. And what's this? A famous 997 GT3 stops by in signature Mexico Blue for some EVOMSit tuning, to enable left foot braking:




A few minutes later, another car shows up, this time a Cobalt Blue Turbo for EVOMSit Stage I and a massive horsepower bump:

 

So much win! And what do you mean "some EVOMSit tuning, to enable left foot braking"? He can't do left foot braking currently?

 

Yes, on a stock GT3, the throttle body will close if you press the gas and brake together, causing the car to buck / disable power.

 

Not good for tracking.

 

really? i left foor brake on high speed turns and havent noticed that, maybe coz i suck

 

Oh I see, didn't know that.

 

A few more updates from this week; out come the plugs and stuff:


The oil tank etc... is off now:



Some of the wiring and other auxillary stuff is removed along with the intake manifold:



Parts trolleys getting stacked with GT3 clothing:


Starting to look more like an engine in there somewhere !



A close up of the heads... amazing work there and I dare someone to do better:P These things will flow a-ok to 500hp and 8800rpms:P


Out with ze camilones!



Valves, springs/retainers:


The valves are in MINT condition with such low mileage you would expect nothing less:


And now down to the pistons:

 

sharky boys this makes me drool everytime I see these posted
- I want this so friggin bad on my 08 Artic Silver GT3...
Also as part of this 3.9 upgrade do you also permanently fix the coolant line fiasco? Perfect time to do it while motor is out.
This is a great option for a low mileage GT3 07/08 to get a 500hp monster...thanks for sharing

 

Hey Alex, how about a package deal for us Atlanta boys...2 Atlanta GT3's to 3.9L for one low price ???


Bill

 

hehe... and yes we actually have done that to every 996TT or GT3 motor we've built since 2006
OK what you have in mind

Here's a few more updates from the last week:

A cart with a lot of "top soil" so to speak:


Second layer:


And even deeper:



Before assembly begins it's off to the parts cleaner:


And once everything is cleaned etc.. (and a few other steps ) it's time to start building with our larger bore cylinders and liners:


Then our cams as well:


Set up along with the timing blocks:


Then we can time them:


And the other side as well:


Starting to look like a block again:


Some special grease left-over...
