Anything I Need to Know

[Nigel Mulvey]

I am just about to do the flate top/SU swap. Does anyone have any last minute advice?

Maker sure you have all the correct throttle linkage pieces for the round tops, other than that enjoy the improvement.

Nigel,

I just did a swap last week with my 260, but instead of the normal HS6 SU's I had the later model HIF6 SU's, which had been fitted to a 240Z I had bought.

I fitted the thicker phenolic spacers which came with the SU's and the other part I used was the shorter accelorator arm that goes between the linkage and the rod that joins the two carbs. The one on the Hitachis was a bit longer.

Apart from those bits everything went well (apart from an aching back from bending over the car for hours) and I can't believe the difference. It's like a new car. Good luck.

Make sure you have everything ready. Intake manifold, Exhaust(headers), linkages, air filter, hoses etc..I ran into problems because I got lazy and didn't replace the freeze plugs underneath the Intake manifolds. Of course they leaked. My round tops spent about a year in my bedroom before I put them on. I had them polished and made sure all my ducks were in a row. I guess it all depends on whether or not you plan on driving it the next day or if you want to wait for parts.

Enjoy!

Nigel,

How did you go with the carb conversion? Did everything work out ok? Notice any difference?

I ran out of time at the weekend. I had a mishap when the water hose to the heater split inside the car pumping litre upon litre into the drivers footwell. By the time I had cleaned the mess up and by-passed the heater to prevent further damage I ran out of time. So I'll try again this weekend.

Where abouts in Sydney are you Geoff? I'm in Mount Annan nr Camden. Are you in the Sydney Z Car Owners Club?

Nigel,

I am in the Sutherland Shire. I joined the Sydney ZCC last month and will be going to the meeting tomorrow night. Are you a member?

Finally got the SU conversion done and the improvement is impressive although with a loose/leaky muffler it's difficult to fine tune things just now.

Geoff, no I don't belong to the SZCC although it is something I've been planning to do for some time.
