I have been debating as to which engine would be best for me to eventually put into a 240Z. I have read about the engine models from The Datsun Z Garage and I enjoy the section on the P79 head mods. First off, I have an engine from a 83ZX, so which head is in that? I know that the 83ZX turbo engines have the P-90a heads, but I am not sure of what my non-turbo has. Whatever the case, does the 83ZX engine have much potential, or is there a better L6 that would prove to be a better option? Thanks.

If it's a non turbo you most likely got a p79(check on the passenger side of the head between the 1 and 2 plugs) I say most likely because i've seen zx with n47 heads but if it's an 83 p79 is a shure bet. good head a lot of potential,I still like n42 the most :)
