R33 Rb20e Box Change

[smurfy1988]

hey guys i have a 1994 R33 coupe it has a RB20e in it atm i'm wanting to swap the motor and box with a rb25de (cant do the det misses on P's)

just want to confirm that when i change the motor over i will also need to change over the loom and the ecu is this all i need to change or is there more?

in the meen time im looking at putting in the RB25de gearbox from what i have seen this should bolt straight up to me current RB20e motor is this correct and is there anything else i will need to do to make this work (current box is slipping and playing up so it needs to be done asap) can get box still trying to find a motor.

any help would be appreciated

Automatic? Drain the oil and put new oil in, see how that goes.
