B2 head is a dx head w/ like 92 horse you will lose power by doing this because it is used on DPFI cars not MPFI so they dont have a aggresive cam at all!

The head is the same as an SI head, swap the cam out, and you're fine.

The y7 is MPFI, so DPFI has nothing to do with it.


You may lose power, even with an SI cam, since the y7 is what, 114hp?

arnt the pistons dished in a y7? cause i know a di15b2 has the pm3 flat top pistons, so that head on a y7 block would lower the compression making it slower.correct me if im wrong.

Ya but why do that? If you want I have a 99 Y8 head I will sell you for a 100$ if you want it! Or if you want to b2 then I have a extra Si cam I took out of head for sale if you want to go that route.. LMK, Kyle
