I assume he's talking about a 996, not a 997 engine.

The 3.6 X51 was an option on the 996. It is NOT the GT3 motor (The Turbo, GT2 and GT3 still use the old split crankcase 964 block, with water cooled heads). It is just a 3.6 M96 block with different heads, intake runners, and DME tuning.

Hey Gearheads,

The 3.6L X51 was a factory option hand built motor for the 996 that was called the "Power Kit" and listed for about $15k. Porsche Germany still stocks the motor so it is available through the RUF folks.

I agree that this should be a Boxster S factory option, but the "Flagship" 911 would have its baby brudda opening a can of whuppass on it.

Thanks, I'm off to change the oil now...... :chicken:

Hasta,
Ike
