I plan on getting SKUNK2 IM...now my question is...would it be worth my while to upgrade to an ITR TB or should I just save my money and stick to the GSR TB?

Thanks in advance H-T!

P.S...I know that the ITR TB is 62MM...what is the bore on the GSR TB?

The Skunk2 intake opening is 64 mm, so how about you have your GSR throttle body bored out to 64mm (from a stock 60mm) so that it can match the intake manifold. That way you only have to spend $100 having that bored out, instead of paying even more for an ITR throttle body that will still have to be port matched to fit the intake manifold so that it will flow optimally. However, it is not that big of a deal not having a larger throttle body, but it would not be a bad idea if you get a chance

 

^ thats a good plan....i have a skunk 2 IM with a 65mm edlebrock TB and they work real nice together

 

has anyone used that maxbore.com? cuz i might think about doing that
