955 S engine rebuild or swap
 

I have a 955 with scored cylinders. Ive heard that Gemballa has a 5.0 bore kit for the 955 but havnt been able to find it anywhere. Is there anyway to get a noticeable performance difference through boring this engine cost effectively durring a rebuild. Also from other peoples experience what is the cost of this rebuild? Porsche dealership of course is pushing me to replace at a cost of nearly 25K(more than i payed for the car).

Also ive heard of a few people swapping LS1 engines into 955s with blown engines. How difficult is this to get the computer to work and transmission to connect? also will the 4.8 Liter enginer swap into the 955?

Contact Flat 6 innovations, I know that Jake has built at least one big bore Cayenne engine.
