Ok I am in the process of building my first z car. I have a 72 240z that is getting a new LS1 with ls6 cam, and a ls6 intake. I am using a 4l60e tranny with a 3200 stall. I am also going to run a 150 dry shot to help it run a little better:mrgreen:. My question is I want to stay IRS so what will I need to do to my r200 (3:90 LSD)so I can handle the daily driving conditions, and a few passes down the track every now and then? I am sure this is a commen question but I have been lurking in the "Search" area for weeks and still cannot make any sense of what is needed. Any info would be great.
Thanks
Mike
