I got a ITR manifold and am about to buy a new throttle body for it probably a bbk one 68mm.. (i dont have the ITR TB) and was thinking maybe I should get a Skunk 2 manifold instead and put the TB on that. Would it be worth it? I have seen the ITR manifolds on plenty of cars making decent power so I know they are good.. but would a skunk 2 perform better? Or it isnt even worth it. By the way I was going to have the ITR manifold portmatched and cleaned up. Thanks for you opinions......

 

if you're having the itr manifold cleaned up as you say might as well just keep it

 

but which would be better??? I was even thinking of gettin a victor x manifold as well...

 

I would go OEM ITR all the way...
If I'm not mistaken, the Skunk2 is just a replica of the ITR manifold with slightly bigger dimensions all around. Bigger does not always mean better.
You want max power?
In that case, maybe the Skunk2 but IMO who cares if you have 3 more HP if you lose 3lb-ft of torque lower in the powerband...

 

unless you have a rather built na or boosted engine the victor x is too big. have your itr manifold cut open and ported.
