Just seeing what interest I get atm. Looking at going a different way. 1- Rb25 NEO head excellent condition. comes with neo bottom half runners, 700cc modded neo injectors and fuel rail and set of neo coilpacks. Ready to bolt onto Rb30 bottom end. 1 set of used (800km) wiseco forged pistons to suit neo head on Rb30 bottom end and a set of brand new unused wiseco rings, on standard rb30 rods. $1200 the lot.
