Royce Posted December 30, 2003 Share #6 Posted December 30, 2003 I think you might want to clarify your sale. Are they actual British SU carbs with a custom air cleaner? Are they Hitachi round top SU style carbs with matching air cleaner from a '70 - '72 240Z, because in the US the '73 240Z didn't come with SU style carbs. Are they some other type of carb? Or are they the flattop, sqaure mouthed Hitachi carbs (not SU like) that came on the '73 240Zs?If not sure pictures are always helpful! Sorry to be so specific, but his is a Z web site!

TTDRIVER Posted December 30, 2003 Author Share #7 Posted December 30, 2003 THE CARBS CAME OFF MY 73 240Z AND THEY ARE NOT THE FLATTOPS WHO HAVE THE MORE 90 DEGREE ANGLED EDGES FOR THE DOME. THESE HAVE ROUNDTOPS AND I DON'T KNOW IF THEY ARE BRITISH OR HITACHI MADE. THE UNIT CONNECTED RIGHT NEXT TO IT HAS A CIRCULAR SYMBOL ON IT WITH POINTY EDGES. FROM THE LOOKS OF IT THEY'RE SU'S. DOES THE SYMBOL SOUND FAMILIAR. THANKS AGAIN Link to comment Share on other sites More sharing options...
Bambikiller240 Posted December 30, 2003 Share #8 Posted December 30, 2003 That would explain the $$$ paid for the carbs. They are the 70-72 SU's. Evidently someone retro-fitted the car with the better carbs before you acquired it. It would be pretty amazing for Flat top carbs (standard on 1973 Z's) to command $150.

TTDRIVER Posted December 30, 2003 Author Share #9 Posted December 30, 2003 NOW WHATS THE DIFFERENCE BETWEEN THE 4 SCREW AND THE 3 SCREW SU'S. I ALWAYS THOUGHT THAT THE 4 SCREW CAME ON THE 70-72 AND THE THREE SCREW CAME ON THE 73'S. MINE ARE THE 3 SCREW ONES. HOW MUCH SHOULD I LET THEM GO FOR? ALSO IM GETTING A 71 MOTOR FOR MY 73, WONDERING IF THATS A GOOD IDEA OR SHOULD I BE AWARE OF SOMETHING BEFORE I DO THIS. THANKS FOR ALL THE HELP GUYS.

Bambikiller240 Posted December 30, 2003 Share #10 Posted December 30, 2003 I am not sure when the 4 screws stopping being used from the factory, but I believe that it was sometime in 71. Three screw round tops were standard on my early 72 (mfg'd 11/71) Flat Tops began to appear in the USA on cars mfg'd after 6/72, which were mostly sold as 73 models. $150 is good money for unrebuilt SU's. I'd take the $$.If you are getting an L24 motor, I (myself) would be more concerned with the mileage on the motor rather than the year of mfg.Dude, it's bad form to use ALL CAPS on these forums. It is considered as SHOUTING, and is frowned upon. Link to comment Share on other sites More sharing options...

Royce Posted December 30, 2003 Share #12 Posted December 30, 2003 I believe that is the Hitachi symbol on the float bowl that you pointed out. It sounds like they are the 3 screw Hitachi SU type carbs. They are also often referred to as SU's in short, although, they are not identical to the British SU's you would find on a Jag, MG, Healy, Mini, etc. As a general guidline, in the US the 4 screw SU type carbs came on '70- '71 model 240Zs and the 3 screw SU type carbs came on '72 model 240Z. The '73 240Z came with the flattop carbs, however, many were changed by Nissan dealers to the earlier type because of customer complaints. Other than the number of screws used to fasten the dome, the next big difference is that the 3 screw carb body has a channel in the bottom to allow water to flow through them. This channel does not exist on the 4 screw carbs. I think I have read that this was done to help the carbs warm up faster in cold environments and maintain a more consistent temperature during operation. There are some other subtle differences but for the most part I believe that as a unit the carbs are interchangeable. From what I have seen, I think that $150 for an average set of carbs with air cleaner is a fair price to buyer and seller. You might be able to get more from the right buyer if they work as good as you say and are in show shape - particulary shinny with all the linkage plating in very good condition.But that is just my thoughts. Mileage may vary!Happy Holidays! Link to comment Share on other sites More sharing options...
