Holy ****! I can't believe it took me a year to see this message! lol hey James,hopes it running better a year later..I also have an exhaust manifold cracked but i am going to just put hearders on..$300 on ebay and nissan wanted $1200 to fix one side! Had to change the radiator twice! luckly it had a lifetime warranty..not a bad job really I was quoted $850 to have it done but got the radiator myself and cost me $110 on ebay.I also got rotors on ebay for like $100 crossed drilled vented..over 30,000 and perfect so far!
