Hr32 Rb20 Too A Rb25

[STLKHR]

Hello thinking of taking my RB20 out and putting in a RB25 Manual maybe turbo aswell what do i need to do apart from the normal motor swap. eg. does fuel pump need upgrading, is the RB25 exhaust manifold bigger, do i need to get the ECU with the RB25 and can i put a turb on it in a later date? (with out changing to much)

Thanks alot guys
