hmmm, weird I have the same as the G0Dz1lla guy sells and all is sweet, but I am running pretty low boost (0.9 bar)

I have them running totally fine, quite nice and simple and with good results. I'm using an RB20 ignitor pack on my RB25 series II If you have tried all that and you are still having missfire problems, then the problem is something else. If everything seems to be running fine on idle and light throttle, but just gets all farty and missfirey on boost, then I suspect your problem is a boost leak. Obvious places are the intercooler and the actuator pressure hose... Hope this helps, James

ello all I know the series 1 and series 2 RB25DET use different coilpacks and that the series 2 coils have built in transistors where the series 1 have an external ignitor pack. Is it possible to use series 1 or rb20 coils on a series 2 car if I use the coilpack loom including the ignitor pack? I'm looking at an external coil conversion, but that will require an rb20 ignitor pack and I want to know if it will fit onto the rest of my loom. any ideas? cheers, James

Also very interested in this. Does anyone know if this conversion can be done with the standard ECU and what seperate igniter pack if any I should be looking for if I have a seriesII RB25DET? cheers, James
