I was hoping to get advice on some supporting mods, that I can get away with so I don't lose that all important warranty. I read about the overheating oil issues and the terrible brake fade. I also would like to replace the stock exhaust because that buzzy engine note after 5k needs to go.

I've read about some oil coolers on here and please correct me if I'm wrong, getting the Nismo oil cooler and having the dealer install it will increase the chances of retaining my warranty should anything go wrong?

Regarding the brakes; should replacing the pads, lines and fluid reduce or eliminate the brake fade? Recomendations would be great.

I am also trying to find out how far I can go with the exhaust while keeping (or try to) my warranty. This is my daily driver until I can get a cheapo secondary vehicle to beat on. CBE and intakes I'm sure is okay, it's the headers and HFC's that are in question.

I've owned my Z for a couple weeks now, but will be out of country for the next few months while I finish my tour. I'm hoping to get a good idea of what I can / plan to do to the car. I don't have alot of money to spend as my money is wrapped up in a future wedding and a house. So I'm focusing on what I think are essential "adjustments" to the car. Thanks in advance for the help
