Eccentric Shaft - differences
 

Hi guys,
I was browsing all the forum and googling as well, but I didn't find any info about the difference between Manual and Automatic Eccentric shaft, between the E-shaft for the high power and the low power engine as well.

I'm looking for this just because I need to replace my E-shaft. The problem is that I've own a UK version of RX8, which is low power (192hp) with Manual transmission.
I have only 2 options (both for different RX8 than main) :
1. To get Auto-low power E-shaft or
2. To get Manual-high power E-shaft

Does anybody know if there is a difference? And if yes - what would you recommend me?
Thanks a lot.

You can use a hi power shaft on a low power engine.
