I used the search button and i cant find anything about this particular subject.

Im trying to fit a RB25DET s1 / s2 Greddy style manifold on a RB25DET NEO

The IAC doesnt fit at all, soo i bought one from a sentra 1.6 and it works fine with the manifold. bolts right up.

Now the fuel rail wont fit at all. So im planning to buy a R33 fuel rail. Now my question is will i have to get r33 injectors if i buy a r33 fuel rail ?? or will the NEO injectors fit the r33 fuel rail??

also will i need a tune once this is done?

Thanks

Skylines Australia has the answer, I think you have to swap or modify the fuel rail. Are you upgrading the injector size?

I would check Skylines Australia like mentioned above. It also seems like someone did a write up on Nico a while back. The injectors are different on the Neo. It uses top feed injectors like the VQ while the S1-2 motors use side feed SR injectors. I think the Neo injectors flow more as well.
