I think I was somewhere under $500 back when I did the 95 a year and a half ago. That was for a mix of name brand aftermarket from RockAuto, plus a few o-rings and hoses from the dealer. Gaskets were FelPro. This included all the hoses under the hood- heater, water on the intake, fuel rail o-rings/grommets. The whole she-bang, except coil-packs. Just have to piece it all together.
