OK it was said here that the s4/s5 LIM is NOT interchangable. So since i have a s5 block does that mean my LIM MUST be s5? Im just asking cause im about to change my UIM and DYnamic into to the s5 version and need to knwo if i can just bolt them up or i should do some port matching. IS there any way to visually tell which it is?

As long as you use both upper and lower of the same series, it doesn't really matter what block it goes on. There might be sensor/valve differences between the two, but I wouldn't know, I have mine all blocked off.

I thought the actuall ports were of a different size on the two manifolds. And didn't I hear on here somewhere that the S4 was actually better for performance than the S5? thought I heard NZ say something like that. NOT TO SURE, DONT CHEW ME OUT PLEASE :P

if you look closely, the s5 UIM has a bit bigger runners than the s4... I havent really compared the LIM so I wouldnt be able to comment on them..
