Actually the CA18det was harder to put into the B12 than an sr20. The ca18 is also not as stout on the bottom end as an sr20det. Still a good engine though.boost_boy said:SR has a more definitve torque and straight-line power band that is bit more aggressive than the CA, but the SR's install into a B12 will require cutting and torching and that to me is a no-no.
