I read the B/D series Interchangeable parts and it says that the Throttle bodies are interchangeable i seen a B20 TB on a B16 but when i put a D16y7 on a Ls nothing. Can a B16 or GSR fit my LS intake manifold with no problem????? thanks !! OO and does it matter if it OBD2 or OBD1 cuz the Intake Manifold is OBD2. THANKS

 

bump!!!!!!!!!!!1

 

You dont want to use the y7 throttle body because it has a 3wire IAC that will screw everything up for you. It could still bolt on but i wouldnt use it. You could use any 92-01 throttle body but i recommend getting an integra as they are bigger then civic (minus 99-00 SI)

 

I have another question regarding this issue, would a b18 throttle body hurt the performance of the b20 or is the difference in bore not that noticable. Wallace

 

the b18 tb is the same one as on the b20...so no

 

so i can use a GSR or LS tb???? or a 99-00 B16???

 

ANY b-series TB will work.
