Triple weber carburetor

[vissan]

I have a Datsun 260z with Hitachi carburetor thats 30 yrs old. I been shopping around, and triple carb are very expensive. I found a used one for a $1000 dollar. I don't know if this is worth the money spending on a carb. How much difference will it make on the car?..Can anyone tell me if this is worth it...

thanks,

Vissan

If your motor is otherwise stock, triple Webers are way too much carb. You need to be looking for something less radical. The most common swap would be a pair of '70-72 SUs, but other options to look at would be dual downdraft Webers or a Holley four barrel.

I am sure Arne knows more than me so this is just hearsay but I have heard others say to stay away from 4bbl carbs. FWIW

I've heard that as well, but I've also heard that they are fine and can be really good. Since I have no experience with them myself, I can't really diss them too much.

Hi Vissan:

Do you mean you found a used Weber, as in "one" 4 barrel? Or do you mean you found a used set of triple Webers, along with the linkage and manifold - for $1000.00.

If they are in good condition - and presently running on an L series engine - then yes, $1,000.00 would seem to be in the ball park for them. They can range from $500.00 to $1,200.00 depending on the completeness and condition of the set-up. Good chrome air cleaners for them are about $75.00 each as I recall... so add or subtract if they are included or not.

I have had lots of experience with triple Webers - I wouldn't recommend them today. I bought and installed mine back in the mid 70's... then spent twice as much as they cost new, on trying to get them properly tuned on my car. No, I wouldn't recommend them today...

That said, many people simply like the "look" of them on the Z Engine, and/or the sound of them at WOT...

Get a set of SU's off the 70-72 240-Z's, including the intake manifold, linkage and air cleaner. Then send the old SU's to "Z Therapy" as an exchange for a set of their Re-manufactured SU's. For about $750.00 you'll have a good running set up, that will supply all the air/fuel your L26 can call for.

If you want more of a "project".. or something not so common... opt for a Fuel Injection set-up. There are several alternatives to look at - just do some research on HybridZ.com.

Good luck,

Carl B.

I've worked with all of them and this is my experience. The early SUs work well under all conditions. The triple Weber/Mikuni/OER work better for racing conditions. The dual Weber downdraft and Holley are okay substitutions for the SUs if you already have them.

As most have said, I believe you will be happiest with a set of well tuned Sus-buy a used set, send them to ZTherapy, and you will be all set-if you are handy, get the rebuilt/bearing kit, and rebuild them yourself.
