What is the Difference between the B16A1 and the B16A2 blocks?
Can I bolt up a 90 B16A1 block to a 99 B16A2 head and Trannie?

I didnt think so. Internals may be a little bit different (compression etc) but everything else should bolt up on the outside.

I guess we will find out.

But waite If the motor is a 91 like mine it is a split year motor they use the same mounts as the A1 but use the A2 cams and 10.4:1 compression the plugs are also grey like the A2s.
