Fellow hybrids...

To change the b18c1 head to ITR plus the TB and Intake manifold which will also include CTR cams...question...

1. What CR would i get with this set-up?
2. Do i really need to change the piston to prop up the CR?
3. If not opting for 2, what is the most cost effective way?

Cheers

PS: I know some will dispute me as to why i'd want to spend on a ITR head but for argument sake lets start can we stick to the question above..thanks...
