Coil Packs?

[All_OVR]

Hi can someone tell me what the differents between RB20Det & RB25 coil packs? i have done an engine swap from an RB20 To a 25/30det but it's still running the old coil packs,I just want to make sure i can get the right one's to get the most out of my engine. Any help would be great.

It depends on which RB20DET and RB25 you have. There are 2 different types of RB25 engines. The series 1 and the series 2.

The series 1 has an external ignitor module which is mounted at the rear of the coil pack cover. The series 2 doesnt have this module as the ignitors are built into the coil packs themselves.

The series 1 RB25 uses the same coils as the 89-92 model RB20DET.

Heres some pics of the series 1 RB25DET engine outlining the ignitor module:

Let me know if you need any further information or assistance with this as I am the trademark owner of Yellow Jackets Performance Coil Packs and I will be glad to help.

if they are series 1 r33 then they are the same as the rb20. series 2 r33 are different, and i think the r34 may be different again.

if it has an ignitor unit (square thing at the back of the rocker cover) then they are series 1. if no ignitor unit then they are series 2
