i have a 89 civic si the throttle body is faulty, would the one from a crx work.CHEERS

 

. ANY D SERIES THROTTLEBODY WILL WORK. I WOULD RECCOMMEND STAYING WITH AN SI THOUGH CAUSE THE HF MODEL IS ALOT SMALLER. AND OBVIOUSLY A DX HAS NO BEARING CAUSE ITS DPFI IF YOU HAPPEN TO NEED ONE I HAVE A FEW LAYING AROUND FROM SOME SWAPS

 

any D or B series throttle bodies work. same bolt pattern. go with B series, they're bigger
