Keep in mind if you are swapping in a RB25DET that you will need to pay particular attention to the series of your motor.

Series 1 RB25DET’s put the igniter on top of the motor, mounted by 4 bolts to the spark plug cover.

If you own a series 1 or 2 and have the incorrect ECU, you can convert the 2 by wiring in your ignitor however it’s far easier just to source the right ECU.

Damage to your ECU capacitors can occur if you are not careful with your RB25DET. For more wiring information and how-to’s on the RB, check out our How To Wire a RB25DET into a S14.
