I have pretty much decided I want to perform this upgrade. The only question is I really don't understand everything involved. I see that FSW sells a FCR "Kit," does it include everything you need to perform the swap? Why do I see various FCR's on Ebay ranging in price from $99 up to $500? How do you know what size bore to purchase? Is there a general rule of thumb on this? I appreciate all the help, this is a great board and I look forward to words of wisdom.
