I've had mine going 135mph (215km/ph) but thats with a stanza SSS gearbox which is a slightly longer ratio than the stock 240. It could of been pushed further but I wasn't down for it cause she was already feeling floaty and unresponsive. Just depends on how willing you are to push it. Need a $^!# load of road though. Takes a fair while to get to those sorts of speeds.

i read somewhere that it gets up to 120 with the stock 4-speed...not exactly sure though.

roger that, manual says 120, top. some folks in my Kiwanis club told me stories about going 150-ish, stock, but i'm sure we all agree thats BS:)

I've had my '72 to 135 ONCE. Scared the crap out of me. Definatly do some suspension work before pulling one of those "lets see how fast can my car go" stunts. It quits pulling hard at around 120-125, but if you keep your foot in it for awhile it will keep gaining ground.

I've had mine to 115, but ran out of road to go faster (no long straight isolated roads here). I can tell you though that it still felt like there was plenty of top end left.

If you plan on pushing your 240 to the limit, plan on suspension and front air dam, otherwise your baby will "fly" in a literal sense!!!

How about a 280z engine/tranny into a 240z? I'm about to buy a car like that.

what kinda suspension work would u need to do?

I've done around 135 with an L28 & 5 speed. If I remember right she was running about 5000 rpm. Got scared and ran out of road.

I remember reading an old piece form a car mag detailing the new 240 from Datsun, in which the top speed was 121 for the four speed and 119 for the auto. Don't remember which mag it was but i think the article is still on the IZCC site.

I have friends who say they had their 70/71 zs to 135mph. The only change from stock was a front air dam for handling.

I was at Bonneville in 02 and the top speed for a Z was 169mph. I am not sure what the rules are for modifying the car but I spoke with a guy that had a 280 motor in his 240z and was hoping to go 170mph. He did not make it at that time.
