Thanks

u need a 2,5 crank if u want to get a 2.5

why don't u buy a 2.5 lump much cheaper than having one built

So i can make 325 from 320 block

Can i bulid a 2.7l from this block. What would i need: ETA crank,320 rods,325 pistons and ECU. What about head?

I am not changing block becouse engine number is on block and i would have to register the car as 2500 ccm and registration is much more expensive for 2.5l in my country
