Living in Idaho like I do. My car seems to come to life more with the colder weather. I have a K&N intake and a 21/2 exhaust with no cat and a Flowmaster mini turbo muffler with a 4inch tip. I have better off the line performance, and increased gas mileage. The colder ir gets the btter she runs. The real joy is after the first snow when the roads are slick. that is when I go out and practice getting sideways and keeping it under control. I ma looking forward to rebuilding my engine this winter I plan on starting in Dec. so I can have some play time. My Z is a true daily driver I take her every where. Monday we get to drive about 400 miles, tues we drive 100 miles and weds we get to drive 700 miles. I plan on taking a lot of pictures of her while I am in Montana and West Yellostone. I will hopefulle have those posted by friday.
Well just wanted to tell everyone how much my 78Z enjoys the cold weather.

 

I prefer injection it is self adjusting for different altitudes and climate. It also gets better gas milage and runs better in the winter. I never have a hard time starting my 78Z. She starts up every time with no effort at all. For power you can go turbo or forced induction adn get all the power you want.
