Will this fit both USDM or JDM B18c1 motors with no problems? I remember the GSR motors have a butterfly intake manifold, but I wasn't sure if that would cause problems if I switched to a Skunk2 manifold.

Thanks in advance to those who help.

 

As long as you get the GSR version, you will have no problems (the flange where it attaches to the head is different from other "B" motors).

The P72a1 ECU will not know that the secondary air control solenoid isn't there and will not throw a code.

I've got a Skunk2 on my bar'd GSR motor'd 89 civic hatchback.

I have the Skunk 2 "Pro Series" IM on my USDM B18C1 and it works great. I dont have the IAB wire plugged into anything and I dont have a CEL.

 

skunk 2 stock gsr

 

a skunk2 vs a stock mani... with both set ups the same... both cars rolling.. say about 35 mph.. both cars downshift to 3rd i guarantee the car with stock mani will pull about 2 car lengths ahead of the skunk2 mani set up

 

If the car with stock mani has a stock ecu P72, and the s2 car has a chipped P28 to change the vtec engagement point the s2 car will pull on the stock mani and P72.And yes this will fit both USDM and JDM

 

the skunk2 manifold **** me off. even after a chipped ECU.. VAFC raised to 56k.. whatever i try to do.. my midrange power lags... ever drive the car with that manifold around 4k-6k? if you hit it medal to medal.. it still lags

 

dont waste your time on skunk2, go with jg victor x
