i currently have the stock dual stage manifold on my b18c in my obd0 90 integra. im running a pr3 b16 ecu cuz of the obd issues, and i was wondering if i get a skunk 2 manifold for it will i notice a BIG difference, or just a minor one? i hear my secondary butterfly is staying closed. thanks guys.

 

you will have more top end with sk2 since your butterflies are staying closed right now

 

the skunk2 will be a good investment.

you will feel big gains, because your secondairies arent opening and its choking the motor.

 

cool, thanks guys

 

anyone got anything esle to add? am i really holding my b18c with my pr3 ecu?

 

YES.

i strongly suggest a single runner manifold or swithing to the p72.
