Just wonderin...., 3S SWAPPERS Options

[0Re0]

Do you guys change the internals or leave it stock ?

I am thinking of the 3s swap and need to compare the pos and neg advantages of the 2nd vs 3rd gen engine.
I know parts and the install info for the 2nd gen are a little easier to find.
I was wondering if you 3rd gen swapers have any trouble using the lower octane fuel here in the US compared to the better fuel the cars are made for in Japan?
Can you run 94 octane and is everything ok? or do you use super blue or additives to make the car run better? Anything at all????? I was reading up on some swaps and i was getting the vibe that the 3rd gen is a P.I.A., I might not want to go with an engine that is going to need more special treatment than my girlfriend .... if you know what i am saying (she might get jelous )!!!!!
I was looking to get some feedback from you guys b4 i decide if the advantage of the 3rd gen is worth the trouble for the extra 20 hp it will give me right off the bat?

Any comments from the two different engine swapers will help me decide!
Thanks a lot,
DG
