Rb25neo Cas Related Question Help!

[beRwick_GTRage]

Hey everyone havibg trouble starting my car.

ive narrowed it down to possbly being my crank angle sensor

the engine i dropped into my r32 was an rb25neo out of a stagea

the cas was broken so i purchased a second hand item from NZ. it was off an rb25neo r34.

is there only one series of rb25neo? if not would the CAS be the same on both?

and did the stagea come with only on type/series of rb25neo?

Are you sure the new CAS is the same as the old? There is one with a plastic cover and one with a metal cover and the wiring for one is the mirror image of the other so reversing the wires from the plug will be necessary in that case.

thanks for the reply.

is the metal cover cas foundon neo engines too?

i dont know which one mine had becuase it didnt come with one.

i bought the plastic cover cas becuase i thought neo's only came out with this type.

This is an R33 one (Mitsubishi)

This is an R34 CAS -(Hitachi) does it match your part number?

I don't think the wrong one would engage properly with the drive on the end of the cam so if it fits ok you could just try reversing the wiring.

R34 CAS

pin 1 = earth

pin 2 = power

pin 3 = 1 deg

pin 4 = 120 deg

R33 Cas

pin 1 = 120

pin 2 = 1

pin 3 = power

pin 4 = earth

And making it easier basically showing that:

1 swaps with 4

2 swaps with 3

3 swaps with 2

4 swaps with 1

mine has the same part number as the 2nd one. and my engine is a neo. it also has the same drive key. so i guess its the right one.

where you trying to say that the r33 mitsubishi cas also came on early neo stagea engines?

Late model R33's came with the hitachi CAS
