IC...hey, more info than asked is better than nothing at all
One other question, in terms of driveability, how does the CA feel during normal driving? Does it feel pitiful under no boost? That's another concern that I had. I chose the B18C1 for my civic, not for max potential, but for practical driveability. It makes nice torque at about 2800rpms and builds nicely from there....not like the B16a that does nothing before 6000rpm.
Anyway, normal driveability is more of a concern on a daily driver than a more purpose build race car...that which will be my 240.
Thanks,
Alex
