US vs. Euro s52

[SwiftE30]

What's the difference? I found the specs on a website that said the euro has roughly 35 more HP than the US, as well as a faster 0-60 by .3.
What is different between the two?

What different? Almost everything.

well since there is no euro s52, there is a great difference

Think of the Euro S50B32 as an early S54 (without all the electronics). As someone mentioned,the S52 is basically an upgraded M50/M52. Entirely different engines. With the increasing availability of the S54 for swaps it's becoming increasingly harder to justify the Euro engine route. Pricing is probably similar between the two, but I have no data to support that claim. Guessing both are around 5K(ish) with a harness and ECU. If you are a real purist then putting the S50B32 into an E36 M3 would be the move. Otherwise, S54 all the way.

One is prettier and makes neat noises.
