What's the difference between a regular and x51 short block? I thought the majority of differences of the x51 were in heads?

This is great news. Under 8k for a short block makes me feel better than thinking of the high cost of a rebuild if anything goes wrong.

Spot on. The shortblock is the same as the non X-51 models, with exception that it probably comes with the x51 oil baffle rather than the normal plastic one.

Porschetech3 thanks for the info!! My plan right now is to investigate buying a motor or building a 3.8L and putting the existing motor in mothballs. I bought this car to drive it, and for the price of entry, I'm less concerned about buying a motor or building a motor. Knowing about the shortblock options is good. Having driven a 3.8L converted 2000 model 911, I was amazed at the torque and performance of the motor. So I'm really intrigued by this option.

while definitely better than $24k for the motor alone, for those non-diy'ers out there, this $8k shortblock will still be $12k installed, so still not a totally low cost option.

Agree. I'm not one of those.

This is true on the 3.6 and 3.8 x51, but the 3.4 x51 kit came with different pistons, also cams, heads, intake, headers, oil pan, and a double scavenge pump on bank 2 head.

Your garage is bigger than our entire condo... Sigh. Maybe we should move out of DC

I commute to Chantilly every day, an hour. But it’s worth it to me to live in the Wilderness Battlefield and have a private range, and 30X60 shop. I have plenty of space to park both my car trailers and no neighbors to bitch about anything I might do or park outside for extended periods. 32 years commuting up north. 32 years living in the country just outside of Fredericksburg.
