YoshiS15

Hi, i have some questions about r33 Rb25det and r34 NEO rb25det, please HELP ME!.
First, i have a Silvia S15 with a r33 rb25det and i bought a NEO rb25det wich i want to swap....my questions are...I have a greddy Intake manifold, ARP head studs, cometic head gasket and a haltech Harness ( all for the R33 rb25det), and i wanted to know if i could use all these with the NEO rb25det or it uses a different intake, studs and head gasket??..is the harness the same or will i have to modify my Haltech harness since its made for r33's rb25det ???

My second question is..what r the difference between the NEO rb25det and the r33 rb25det ??..is the only difference the Head ?? i have CP pistons and eagle rods....are they the same and can i put them in the NEO rb??.

If i put the NEO head on to my R33 rb25det...will it become a NEO rb25det ?? or its better to swap the whole engine??

PLEASE PLEASE help me! i want to swap the neo for the r33 rb25det..and put my greedy intake, head gasket, arp, pistons, rods, Haltech, etc.
