US vs ROW differences?
 

What are they?
I used to have an Euro Carrera and it ran just fine on CA premium gas regardless of the higher compression and single plugs. What does it take to convert? Can't I just swap my cylinders and piston out?

Pistons 10.3 vs 9.5. Pistons have same casting numbers but in comparison the euro is several mm taller in comparison.
On SC s there is a cam timing difference
The brain for the euro doesn't have oxygen sensor system

There's got to be more than P/C and cam timing. Otherwise it would be way too easy to swap over to Euro specs.

Well, I've built many of each over years, there is no special, crank, rods, heads, cams, injection,.
I don't know what more you could change...

Thats it. :)

Some ROW Carrera's didn't have cats as they were optional.

Correct me if I'm wrong but I think the rows distrubutor has the rev limiter while the us version is tucked behind the speedo.
