Icon2 B18b/B20 JRSC on a B18C?

I have a Jackson Racing Supercharger thats for a B18b/B20. I have a JDM B18C Type R in my eg civic hatch. I did not know if I could modify the manifold to make the JRSC work for my engine. Can someone help me out?

No, it won't work, the gsr intake manifold has a unique flange/bolt pattern. All other b series are the same except gsr. Two ways to make it work,
1. Get an aluminum gsr intake flange, cut the flange off the super charger and pay someone to rig weld the gsr flange on, this doesn't seem like a good option, but it could be done.

2. Buy a b16 bare head, swap all of your distributor, sensors, cans etc. Into the b16 head, then the super charger will bolt right on, this will probably be easier than the cut and weld option.

nice catch man, So OP........Do you actually have a type R motor? B18C or
B18C5?

If you do have a C5 then the blower will bolt right up.
