I recently bought an obx intake manifold and my stock d16a6 throttle body doesn't match up. Is it a defect or do i have to find a bigger throttle body. if so how big? thank for the help.

 

obx maniz on the d series use factory on up to 66mm tb....not sure why your doesn't fit maybe someone can post a pic for you of a d16 tb to look at

 

WHAT YEAR WAS THE MANIFOLD THAT YOU BOUGHT, AND WHAT YEAR IS THE TB.

 

the mani said it was for all d series 88-91 and my tb is off a 91 d16a6. i went to the local junk yard and they have 2 second gen integras and one first gen. but no civics older than 94. i'm wondering if i could just toke the tb off one of those. will that work?
