S1 Motor To Replace S2 Motor.

[ShayneJ]

Ok, here goes:

Spun a bearing in S2 motor, and mate has a spare 25 out of a stagea, so he's been told. So assuming its S1 motor seeing it has an ignitor box at the back of the motor. The motor will be going into a S2 R33. Heres the info and questions:

1) I have a rb20 computer tune to run the 25 (assuming using S2 AFM)

2) AFM's different between motors, how will this effect things. What can I do about it?

3) I have splitfire coil packs, will these run in the S1 motor with the ignitor box?

4) Is there anything else I am missing?

5) are there any major differences between the motors?

Is there anything I missed??? Was hoping this be out and in swap without stuffing around...

Cheers

If the engine is from a Stagea, then it should have a AWD sump, with the diff hanging off the side. Pretty sure all Stagea RB25 are S2.

If you have a RB20 ECU running a S2, how does it control the VVT?

The simplest method to use the other engine is to transfer all the electrical items (AFM, coils, etc) from your dead engine onto the replacement engine.

Oh ok, so may not be a stagea...

Not sure how it runs VCT as i've had the car for 4 weeks. Purchased as is but used a 20 computer as they are easier to tune than the S2 rb25 ones?
