Porsche need to be told then, they dont think they are different. (PET)

They may spec replacement parts as the same but as built from new they are different.

The 993 turbo con-rod is the same all the way through the 997tt. The 993 NA rod is tiny by comparison.

Now that's not to discourage someone from converting a NA to turbo. Even with stock rods 400hp is safe if keeping RPMs in check.

Yah, gotta watch it with Pet and updates. To really tell, you need a backdated reference at the time the cars were made to check the part numbers.

If you look it up on Sunset's part web site

http://www.sunsetporscheparts.com/au...at/engine-scat

the current part number is from a 996 - 996-1-3-975-70. Blasphemy!

Cheers,

The 959 was liquid cooled? I actually did not know that if it's true.

Just the heads.

Many numbers were listed, also a chassis break which may add confusion.

All of these numbers are now superseded to the 996 106 975 70 set of 6
