engine ordered. what else?
Was hoping you guys could recommend what else to replace / upgrade or just check while I'm at it. Car is new to me so the more I learn the better. Also think I will put stock pulley back on and have dealer flash it( it is my understanding that this is all I need to go back to stock) just until I make sure everything is 100 percent.
So please pitch in looking for any kind of useful information. Like I said I don't know much myself. Thanks
