RHD 1972 Carb linkage

[Grif260z]

Look I need help. Just bought a right hand drive Datsun Z and i am putting a 1972 L24 engine in it because that is all i got right now. I have never owned a Right hand drive one, i owned a 1974 260 with a clifford intake and holley 4 barrel. I don't want that on my car so i would like to make su's work. i have several sets and i will tell you honestly, i have always loved datsuns but know nothing about SU carbs or what the diffrence is between them any info or pictures you've got please e-mail me. d_lauhoff@hotmail.com. I am going for a wangan midnight look for the car and since it is right hand drive It is kinda rare in the states, Especially in the midwest. Any help would be cool

I'm willing to help you in any way that I can ( I have three Japanese market S30-series Z cars ) but I'd prefer to do it here on the forum rather than in direct e-mails to you. That's what the forum is for.......

You say you already have a Japanese market car, and a set of Hitachi-licensed 'SU' carbs - so you should already have most of what you need. What is missing from the base car? The stock linkage is quite simple, so you should be able to fabricate anything that is missing.

What do you need?

Quickest route to a solution would be for both of you to post photos of what you have, one will show what is required and the other will show what's missing..... www.ztherapy.com more than likely will have any of the needed parts. Again, need photos....

Dude, Datsun owners are the best!! thanks for your help. it dosen't look like there is much change between the two so i can just make new linkage then im pretty well set. Any Suggestions for what kind of carbs to put on it? I am runing stock internals on this engine so just looking for drivability. I have both types of carbs says my datsun friend, 3 screw and 4 screw, also looking at anything aftermarket like webers or mikuni or anything that nature

As a '72 you should need 3 screw carbs.

Take a look at the attached scans, which are taken from the 1972 RHD Export market factory parts list. They should give you a pretty good idea of what you have and don't have, I hope.

You don't say exactly what model of S30-series Z you have ( a 1972 Japanese market car could be any one of six different model variants ) or what kind of condition it is in, so there's no way for us to tell you what you need to source. If you need any more help, then perhaps give a few more details?

Dude, Datsun owners are the best!!

I don't own any Datsuns. I own four Nissans and an Audi.

If you have the foot feed and the rest of the stuff inside the car, the blow up looks like everything else through the firewall and on to the balance tube is the same as the US models. Pretty sneeky how they did that.....

No, it's a little bit more complicated than that. The 'Bell Crank' and 'Bell Crank Bracket' in particular are completely different between RHD and LHD versions. Hopefully they will still be attached to his '72 RHD car, so he won't have to source or fabricate them.

The ball-jointed actuating rod that sits parallel to the firewall is very long on the RHD, but if that is missing it would be fairly easy to replicate.

I got with Steve this morning and he has everything you need with the exception of the long dogbone that goes across the fire wall. He can build you one fo those.

Give a call if we can help......
