I have a JDM B16 SIRII motor with stock throttle body/manifold and also have a spare ITR manifold. If i swap the ITR manifold is it a direct swap i searched and some say its a direct swap and others say you need idle valve and gsr fuel rail for the swap is that true?

thanks

 

anyone with stock b16 fuel rail and ITR manifold or did you upgrade the fuel rail also?

 

i believe its a direct swap, but its better, and bigger

 

well b16 is better than type R manifold on low/mid range and type R is better for mid/high range and better for built engines from the research.
I want to know if the stock b16 fuel rails are good enough for the type r manifold or if i will run into problems later on thanks

 

the R man is fine the rail and injectors will fit. you might not have to use those spacers however. as for the IACV I think the jdm one might not bolt on. you will need a 92-95 civic one or 94-LS. also I believe you need a different Throttle cable and bracket.
