One of the engine's (with the higher miles- who could that be? is getting more of a work-over... In the connecting rod department we do feel it necessary to get new rod bearings and bolts.

Here's you can see a comparison between the pankl GT3 rod and a Twin Turbo one (yes I know it's a little bent lol!):


The Titanium GT3 ones are obviously lighter but by how much you ask?


Certainly helps the GT3 rev quicker

So after 37.5K on this motor you can see that there is indeed some decent wear on the rod bearings, which we're replacing.



All well and good but never mind the work to do that but because we're dealing with one-time use stretch bolts you need 12X new ones:



Take a long hard look at this $58 dollar bolt:P At least the bearings are only $19 a piece....

 

A few more fun things for today fellas...

In go the lifters..


And the intake plus exhaust cam shafts...


There's a few fun tools here including the factory timing blocks that you can't really see... It's a two person job really with some MEGA wrenches


On goes all the top side "faff" including the wiring harnesses, intake manifold etc...


One other change we're making is removing the gt3 pulley in place of the RS one (also used on new 2010 997GT3s mind you) as we're getting a much more rev-happy engine here...

Original one comes off:

On goes the RS one...


In reference to the earlier post about the factory rear main seal and the leaking you get... this is a picture of how it's supposed to look- no leaks with the 996gt3 one.

 

Been busy for a few days so here's a few more updates and for the silver car

Here's those magic steel liners that help make the bigger 3.9L bore possible


Those trick head studs:


The rods along with new bearings and new rod bolts:


And installed:


All in...


Gasket...


More..


Some cam timing (two person job along with some factory tools and then some)


Most of it assembled...


Ready to go back in the car...


Back in the car...


The "stereo"


Then looking to the other lift we have a pair of other 3.9L's

 

But the silver one was not yet done... Slight smell of coolant in the front and with 37.5K of unprotected mileage the front radiator was a little worse for wear...

Off came the bumper...


With some cleaning look at some of the stuff she'd collected:


Here's the old one vs' the new one... Not a pretty sight


With the new radiator in place we added some protection with the Cargraphic screens:



And now the silver one is ready for some action again.... but before you know it in comes another whitey:P

 

This is such a nice build. This car must be a beast with that much HP and high rev. Great work!

 

It's a great rev-happy 500hp na motor Got three of these here right now

 

Nice, I somewhat know the feeling. It's just mine takes 4 more cyclinders to do it. Congrats again on such fine work. Very impressive.

 

Yes you do! SL motor in the Lambo is a PEACH. Rev-happy... as good as it gets

 

Nice work guys, have you done two 3.9Ls so far?

 

What a shame you are not in the UK

Looks like it will be a Scuderia or RS Tuning GT2 for me. Or an '71 ST rep with 310bhp and sub 1000kg....
