I am curious to know if the 70mm Skunk 2 manifold would fit an euro-R manifold or would the TB stick (meaning would the butterfly get stuck)? Thanks

 

Are you asking if the skunk2 throttle body will fit on a Euro R manifold?

If you are,

What's the sense of having a 70mm throttle body on a stock intake port? You should bore the intake manifold out to match the throttle body no matter what. Not port matching them would cause a step up that would kill any gains that you might gain going to 70mm.

An S2K throttle body and port matched Euro R manifold would be a much better match.

 

Oh I understand that. I want to get the throttle body so that I can have it machined. I just want to make sure there will be no problem with sticking and it will clear everything when its bored out. I think I should stick with a 68mm

 

Yeah from what I have seen 68mm is the max bore for the Euro R manifold.

 

I spoke to Rosko Racing and they said 70 is cutting it close so I will stay w/ the 68mm

 

and I heard multiple problems with the 70mm TB when 68mm has less problem. Mine's a 68mm S2 TB, and it does stick around 1.5K at times after I drive it for more than an hour.
