 -"Chains baby, chains.......Z will grip like a champ. (n/m) - Wolf [Pittsburgh] 14:56:58 05/10/00" How to Check Turbos: "1st remove exhaust and pre-cats. Then fire that mother up, rev it to at least 5000 rpm and then stick your finger into the hole on the back of the turbo. If the turbine grinds your finger down, then your turbo is working. If your finger gets ground off farther than the second knuckle, then your turbos are good for at least another 60k miles! Don't forget to check both sides." -I am Z-ing Double |
