Ok, here is the predicament. If we are to goto a rb26 head on our new 30 further on down the track. What absolutely has to change in order for it to work. Obviously we are looking at changing the bare minimum, so we can retain the powerfc and loom till we get an autronic later on.
Can we use rb25 ignition setup as we sport s2 coil packs. Are the bolt up patterns the same? My experience with nissan tells me they might.
Obviously we want the std cold side of the head, so is it possible to use our side feed injectors if we can adapt the rail to the 26 plenum? Or is this a big task or not possible incase someone has already done this.
The other things im not sure about are the sensors that are in the plenum? Can they be switched for rb25 ones so we dont have to go rewiring stuff or messing with the loom. Does the throttle cable need to be altered or should it be fine? CAS? are they the same or will something need to happen there?
I cant think of anything else other then we will need a new exhaust manifold.
Any and all help is appreciated.
Cheers.
