No real need to touch the ITR manifold & std throttle till you're trying to push past 145kw @ wheels. Once you're aiming past this, attention to detail really counts so you'll need to cut the manifold open & sort it out.Quote:

Luckily it is easily dissasembled.
Most of the work can be done with emory mops (Pferd is a good brand) of various sizes & grades.
If you're chasing really big power, the secondary runners are ported to join the primary runners & the butterflys are removed.
This gives large open ports & allows easy match porting to your (asumed) ported head. Throttle size in this instance should be 65~68mm
Personally I prefer the smaller throttle as the drivability is better with more linear power delivery per throttle movement.
Of note, both the ITR & VtiR when only mildly modified / ported will reward you with 64~65mm throttle use.
Going larger can often hurt power & drivability with loss of air speed. (But the use of of a tuned length CAI can help mask this.)
Beeza - Consider yourself told.
LOL @ Beeza jumping to spastic conclusions.
Wow thanks for that Adrian mate really appreciate that! Gotta love it when someone is willing to explain something to make more sense. And lol bad luck Beeza he got ya there man :P
Did he? Or did I get him (to say,that is :) )
Whatever the answer is,that's the stuff we wanna hear!
That's the good stuff,that's the stuff I can work with!!
So Thank U Adrian,good sharing!
RePPed!
Just wanted to break the spell of people thinking that the Skunk2 Manifold is just a copy of the ITR manifold.. Here are the main differences. The Skunk2 Manifold was in fact actually designed off the Type R manifold but there are changes that were made. We have made changes to the manifold for the Pro Series version by adding 8" tapered runners and enlarging the plenum. With the Skunk2 Manifold you can port the manifold to run TB's as big as 75mm while the OEM manifold will not be able to go past 64mm where the Skunk2 starts with out breaking into the IAC passages. The manifolds now come in both Black and Red wrinkle finishes to match your OEM valve covers.
LOL consider yourself told, i like it.
hehehe
I had to work real hard for that info LOL
