I have a Ek with a GS-R motor and a friend of mind can get me a really good deal on a new throttle body because he says that gsr throttle bodies aren't very good especially becuase i have a skunk 2 intake manifold. So what i want to know are the specs on a CT-R throttle body mm. and JDM/USDM IT-R throttle body mm. which is better to get.

 

As far as I know they're both the same: 62mm

 

Huh? I had a GSR TB on my b16 it worked fine! I just didn't like that crazy throttle cable bracket so I switched. Don't wast your money man. Stick with the GSR TB.

 

you mean that giraffe lookin bracket. it sure sticks up alot but it works.

 

dont get the ctr throttle body its the same size as a stock b16 throttle body.

 

Where did you hear that?
B16A1: 58mm
B16A2: 60mm
Type R: 62mm

 

Where are you getting that from? I've always been told ITR is 62 and CTR is 60.

 

 

Keep what you have. Get it bored to 64mm if you want something a little bigger.

 

CTR TB = 60mm
ITR TB = 62mm

 

i think the jdm itr tb is 64mm

 

nope

 

not sure about the ctr, but the ITR is 62mm

 

Aaah, I take that back, you might be right about the USDM CTR TB
I've been told many times both JDM type R TB's are 62mm, definately the ITR anyway.

 

we have a USDM CTR??
