68 2000 New Carbs and Intake Install
Hi All,
I'm getting ready to install a rebuilt set of SU's on my 68 2000. I have a complete replacement set-up including carbs, intake, linkage and heat shield.
Any recommendations/suggestions on removing my current set-up and installing my new/rebuilt set-up. Any special tools or techniques required.
Hoping for a simple trouble free install, any help would be apricated.
Thanks
Henry

Re: 68 2000 New Carbs and Intake Install
Having just done this multiple times while working on my cylinder head, the worst part for me was reaching a couple of the manifold nuts that are nicely tucked behind the exhaust header tubes. I found that an open end wrench that wasn't too long worked best for me. Others may have a better way.

Re: 68 2000 New Carbs and Intake Install
If I recall, the nuts for the intake and exhaust need to use a 12mm wrench instead of a 13mm due to clearance issues. Pay attention to how the spacers are located in the exhaust studs unless you have a newer thicker header flange.

Once the carb bodies are mounted on manifold I always peek into them to set both butterfly valves to sync before putting domes back on. Use the adjustment screw for each carb.

Re: 68 2000 New Carbs and Intake Install
Do you have to replace the intake? So much easier if you don’t , as then don’t you have to do a new exhaust manifold gasket, I believe.
I just did the carb swap and it was easy enough.
Are yours Z Therapy?They sure do a nice job.

Re: 68 2000 New Carbs and Intake Install
I also replaced the manifold studs while I was in there but that might be difficult while the head is still in the car. I used Dorman 3411 studs...which fit well except a couple needed to be shortened about 1/4" as they interfered with head stud passages. These are cheap to do though if you think yours are shabby.

Re: 68 2000 New Carbs and Intake Install
12mm socket with two extensions and two u-joints makes pretty short work of those pesky flange nuts
Oil a little low? Time to get a longer dipstick:)

Here are some before and after shots of the manifold studs. I marked the problem-children in red.

Nissan still sells those studs BTW. The part numbers differ based on the length.

Re: 68 2000 New Carbs and Intake Install
Or you can run a die down each one to clean the threads and make it easier to install the nuts in tight places.
