Two More 3.9L Projects Underway @ Shark Werks
Hey guys,
It's been a while since we posted an update about our long term projects so I thought I'd start another thread.
While I can't show everything we're working on, there's a new 3.9L 997 GT3 build that's unique. And on the lift she goes!


This car came in with approx 58,000 miles, mostly used as a track car and already equipped with a load of goodies: EVOMSit software, exhaust, full Ohlins 3-way coil-over setup, these HRE wheels, Guard LSD, roll cage, racing seats and all the gadgets for timing/video on track days. We are doing the 3.9L including a bottom end refresh and valve job, and the coolant leak fix.

Notice the HRE P40 wheels and wheel studs.
A short time later, James has reached a milestone in surgery:

With this kind of mileage, it's expected to have a little dirt and oil on the exterior.

It looks nice from this angle:

But a lot smaller from here:



A previous shop had performed a fix which was intended to seal the coolant pipes in place, by welding. Unfortunately the welds did not last or were not up to the job and therefore leaked over time. We now have to replace a couple coolant housings and fix these troublesome lines in place using a screw and loctite. More info on our solution is available here.
And a bit dirtier once the intake is removed:

The valve covers are removed:

More sludge removal and more parts coming off:



Now we're getting somewhere, with the pistons in plain sight.

The case prior to splitting:

And after, showing the crankshaft and oil pump.


And here we are giving the parts a bubble bath in our parts cleaner. This is quite a long process considering all the components to this engine. But it does ensure everything is clean and seals like new when reassembled.

While the parts soak, James turns his attention to this 2012 Turbo, which is receiving our exhaust upgrade:


Here's a video in case you were wondering how a new Turbo can sound compared to a GT3

Before we get back to work, a GT3RS comes in for some RSS suspension goodies and EVOMSit software, as well as our GT3 bypass exhaust.

Back to our big project, we can take a peak at the valves:

Since the car has higher mileage than we've seen and it's been driven very hard, it requires more attention on the internal bits for freshening up than a typical build. New connecting rod bearings and bolts are being used, and the heads are being worked on and I'll have some "after" pictures soon.
The results of the cleaning process:



Ready for new rod bearings.

Beginning reassembly...


The case is reassembled with new seals and the next step is pistons, which will have to wait for another post.

And as we're buttoning up this project, another is on its way. A white 3.9L 997 GT3 much like this one, and this time the car comes from Florida; its owner is also shooting for Ohlins and a handful of other upgrades...

Great pics! Thanks for posting.
Very interesting, especially to those of us who will not see the internals of our motors.
I think we're going to see more & more 3.9L's....just to stay on par with the 4.0L & a few steps ahead of the 991.
