doing a JDM ZC swap into a 91 SI civic HB. i need to know what intake manifold is better to use. the stock one in the car is in good shape with all sensor good.
the ZC has 2 busted sensors, which i can take off the stock one and use. BUT which one flows better? is there a difference?
need anwser ASAP!!!!!
TIA

 

The Si one is 4-1 header it sucks its on my ZC cause i can't afford a 4-2-1 header yet. But your stock down pipe is made for a 4-1 so the ZC header won't fit anyways but it would be better then the Si one. OOps intake manifold....the Si one doesn't fit its just slightly different the ZC one is better anyways. The fuel injecters flow at a higher rate.

zc fuel injectors flow at a higher rate? interesting..
do you have some specs for both? (si and zc)

 

ZC and si intake manifolds are different. Just swap the sensors over...

 

ZC intake manifold is unique. Nothing else fits, and it fits nothing else.

 

86-89 Integra and ZC are interchangable. the ONLY exception.
you wouldn't want to, but you could.

 

You are right, I forgot about that, and you are right, they flow very poorly. Would strangle the ZC. THere is nothing you would want to put on the ZC other than the factory intake.
