I got a b18c1 swap from my buddy, gave him my d16y8, $200 on top and will help him pass smog lol. The motor has 180psi in cylinders 1,2,4, cylinder 3 has 90 psi. The head is off and now im debating on what parts to bye. The swap came with AEM tru time cam gears which my brother wants for his b20vtec which been shaved 80 thousands (yes i know thats a lot but he got the head like that) what are the benefits of those AEM cam gears if I keep them or will they be of better use to my brother? Now to the rebuild, which main bearings should I use? will the new rings fix my compression problem? Is it worth getting ITR pistons and will they work with my rods, wanted b16a2 (PR3) pistons but they wont work without modification to the rod Thanks in advance for any advice and please ask if u have any questions. Thanks.
