X51 engine swap - what's involved?

I'm considering having installed a x51 Porsche remanufactured engine to replace a "regular" engine that recently died.
Does anyone know what additional parts and procedures are required to do this?
I assume a stronger clutch, a third radiator, reflashing the chip, anything else?

i have been told no need to swap the ECU aswell, they just Reprogam it... I have also read X51 is Under-Rated, performance comparable to GT3... Engine Performance only, not Handling....

I was told that the price for a X51 is the same as a regular 3.6L.
The only thing you need to add is the sport exhaust and that is listed for $6k. However, I was told you don't really need it.

I've done this myself, so here are the facts vs the above speculation:
x51 engine price is the same, the core is $600 more (but you must have an x51 to get the x51 core price applied so if you don't, the engine is really $3659.50 more than the non-x51). You need two things to get an x51 engine to go into a normal 996: the special A/C line at the compressor due to the much wider/taller aluminum manifold, and second, the proper software flashed onto the engine computer. The software is hard to get because the Porsche computer limits the "flash" only to VIN numbers that have been authorized (by PMNA?) to have an x51 engine. My dealer did the flash for $70 - much cheaper than an aftermarket tuner which is around $1000+. If I didn't have an authorized VIN, they could not do the flash - their computer won't let them release the software to the car. Otherwise the A/C line is a $60 part and requires refilling/recharging of the system after changing. After that, the engine plugs right in. It does not require sport exhaust, either.

If you don't have the engine check with Suncoast. When I was considering a reman engine they would take a 3.4 core for a 3.6, maybe a 3.6 for a 3.6 X51. They were the only source I found that would/could do an apples to oranges core. Don't know if they still will.
