The factory fb25 is 10.5:1 so great for boost, but higher comp NA pistons arent hard to obtain
I don't think the FB25 platform is compatible for many reasons besides the starter. The FB25 has a longer stroke and likely has a difference in block dimensions, so heads and intake manifold are likely not going to line up. The FB25B also has 10.0:1 compression, and it doesn't have direct injection. The FB25D has direct injection on a 12.0:1 compression, but still, it would be better to do a FA24F block swap or FA24D engine swap than attempt the FB25.
