Ok guys, here's one for you. I'm thinking bout buying a series2 rb25det motor set. A friend of mine said that I need to find out about the possibility of the ignitor chip thats in the ecu on that motor going bad. I just need to find out what are the advantages/disadvantages of going series1 motor or series2. Are there any? I'm just trying to find out before I pluck the money down and yes I did search the topic, none addressed my question.
