Hey guys,

Just wondering if theres any 260z owners out that would give me some input if my car is running right. On a strait away i can barly get this car above a 100mph...I know somthing is deffinalty wrong B/c when you open the glove box u see the tire pressure Recommendations ... Over 100 and under 100../.. yea this is Definitely tellin me somthing is wrong.. In the car im runin a L28 engine out of a 280z with a 4 speed tranny.. as for the carbs go i have an earlyer set off off SUs out of a 71' 240z...Also as in regards to Mpg.. im getting under 20 mpg. Is that normal? i know this car needs a tune up...

Thanks,

Steve

I get about 20mpg on freeway and about 15 in the city. If I am driving more aggressively I get about 10-12mpg in the city. I have gotten my car upto 105mph along time ago. I thought it was going to lift off. I never did it again. The top speed for a stock 260z is about 125mph. The stickers on the glovebox door are referring to the 175HR14 Bridgestone tires. I don't think it matches with new tires. I have 195 by 70 14" tires and I inflate to 32psi. the numbers are different for the original tires.

OT: Thanks for the link Larry. I know that the California export 260z's were rated at 139bhp, but my car was bought from Illinois and the plate in the engine bay says 162bhp. I am assuming this is because the California cars had to meet the smog laws.

Hi Steve,

It's a bit of a tangent, but is the glovebox tyre placard in Kilometres per hour, or miles an hour?. For safetys sake it's a big difference. 100mph is ~ 160 kph...or 100kph is ~60 mph.
