My buddy just got a B20 swap in his hatch. Were wondering about aftermarket parts. Im assuming Manifolds for all B series interchange since there's a B18 intake manifold to clear the hood. And aftermarket companies sell only one manifold for B series Turbo kits. Is the Only Difference between a B18 and a B20 just the Bore?We were also wondering what cams will work in his car. Thanks.

 

I have a CRV with the B20B and i just installed a B18 intake, altho im having a vacuum leak from somewhere, i have to narrow it down tomorrow., but the answer is yes it will bolt up but the intake runner are a lil smaller than the b20. there are a few more vacuum lines on the B18 than the b20. as for the cams i want to say any B-Series but i could be wrong, if somone else knows plz correct me.
