Introduction and Question regarding this forum

[Clatter]

Hi Erik,

Welcome to the best website on earth!

I have a couple of questions...

Regarding the 923 trans from the 912E:
This is a popular choice because of the gear ratios suited to the type4 engine, and the release mechanism that fits easily.
i did hear somewhere that it is weaker than the typical 915.

True?

What parts would help beef it up some more for drag-racing type starts?
I heard that there is a later-style side cover that would help?

What are my options for an LSD?

Oh, and thanks for sharing the wisdom.
A little experience is a very valuable thing to us trying to find our way.
