I'm thinking about purchasing a cheap 1980 280zx in the neighborhood as a learning project. I'd like to turn it into a DD, cruising in GT comfort and economy while having something sporty and different. I realize I'm in the minority here and I like power, too, but sharp looks, efficiency, reliability, luxury, nostalgia, and uniqueness rank higher to me than ponies. One of my goals is to achieve 30 mpg, which to me is reasonable without being a hyper-miling nut.
My question: Is it possible for the L28 to deliver my mpg goal or will a transplanted 4-banger be needed? If so, I've read the S2000 posts and that sounds do-able but pricey. Could the knowledge base here recommend any other (affordable) lumps that would put out at least180 hp, transporting me to work within my 30 mpg budget in a reliable fashion in the lightened 280zx?
PS--I currently use a 1993 MR2 as a daily driver, 34 miles of mixed city/country, and get 31 mpg. The 5 spd MR2 is fun in a go-cart sort of way, reliable, and efficient. But it's sooooo small and hard to put on, plus it beats me to death as it rides like a brick. Sixty mph turns the tach to 3K and over 4K at a squirrelly 80 mph--way too busy and annoying.
