I have come across a used b16a pr3-4 p2t intake manifold from a 99-00 civic si - with throttle body - and want to know if it will bolt right up to my b18a '90 integra. I've heard they're a better b series manifold due to the shorter, wider runners and I'd like to know what it would take to make it work. Is it a bolt-it-up type deal or are there any wiring or vacuum demons to iron out? Throttle body ok? TPS and MAP sensors are available if I need them.

 

i dont think it will bolt up to your LS head

 

I'm fairly certain it will bolt up. What I'm concerned about is the ODB discrepancies. I'm betting I'll need to use the plugs for the proper ODB and pop them onto my existing harness in place of the odb0 plugs that are already there.

 

Its OBD not ODB

 

lol. me == tard.

Been trying to gather info on this online. From what I can tell, everything should bolt up fine. I just need to use my original injectors. Lucky I have the fuel rail, too!

 

I am pretty sure that it wont fit. It may look like it will but there are subtle differences that do not make it a strickly bolt on affair.

Its too bad a lot of the pics are lost. You can see that the coolant passages as well as the bolt patterns are a bit different in the gaskets. Here is another comparison.

You will probably gain some top end power but will sacrfice low end power. It would probalby be a lot easier to get a skunk 2 or blox intake manifold designed for the ls.
