65mm tb or 68mm tb?

i'm planning on boosting after rebuilding my b18c1 and just wondering which tb would be best for force induction? it's going to mate with a aebs intake manifold.

I always thought it was pointless to go anything much larger than your charge piping.

I went 68mm with a 2.5" charge piping.

AEBS has a 65mm intake port, so youd have to port for a 68mm.
and 2.5" charge piping is 63.5mm so 65mm would match the 2.5" piping well.
