Thanks yes its a 1984 nissan silvia s12 rsx fj20et turbo engine jdm only.Drives well Power Steering,air con the s12 everyone wants i think the only one in England.
I have always wanted a VG30 engined one, ever since I saw the works Nissan cars rally back home..
not sure about the s20 same as the engine in the skyline R31 RS=X .I thought the s20 was a 6 cylinder.
I believe that the RB is the natural descendant - doesn't answer your question I know...
