I built my setup for about 1400 so that would be about right you still would have to source carbi or efi setup, ecu, then tune, plus that exhaust manifold would need some baffled work in 2/3 as they straight out! There was a member making nice manifolds here for about 700/800 mark, t25 about $100 second hand, oil/water lines 150/250 including sump mod, dump 200, carbi 50/100, efi 1000, ecu 600/2500, so depends what you want!
I bought a ca18det, and r30 stumpy, ecu, and loom for less that that! Depends what u want
