I just got finished tweaking my new ZTherapy carbs today. Had I known the difference they would make, I would have ordered these two years ago. My car has always run rough and rich and I could never get the originals set right. The car runs so smooth now and has more power than it ever has. Not sure if others here on the site have had any issues or not but I am extremely pleased, they were well worth the cost to me.

I rearranged some items under the hood of my 260z and I need to replace several fuel hoses. I though I'd go with AN-6 instead of rubber hoses and worm clamps but I'm a bit confused on the connections. I'm assuming the threaded connections are all tapered BSP since the components are Japanese and nothing had O-rings. Because the vehicle traded hands a few times there is a strong possibility that some fittings (pressure regulator in particular) had NPT used where BSP should of been. If I use BSP now will that be a problem or will teflon tape fill the gap. It looks like there is a lot of pipe dope there now to seal the thread and it seems to have held up to the low pre…

@Captain Obvious & @zKars Just checking with you to confirm that the 87 Fiero has a combination oil pressure switch and sender? I wish to continue to use my oil pressure gauge and have a cut off switch for an electric fuel pump. https://www.rockauto.com/en/catalog/pontiac,1987,fiero,2.5l+151cid+l4,1249141,electrical-switch+&+relay,oil+pressure+sender+/+switch,4588 Thanks

A friend of mine is renovating a Z for his son (that is love!!). He reached out to Bruce at Ztherapy and found that there are currently out of SM needles and nozzles, not sure when new stock will be in. I have looked at other sources, without much success, and was hoping someone might have any ideas? Thanks!

Hey everyone, just recently got back into the datsun game with an early 74 260z. I've acquired a few extra parts that I don't really have use for and would like to sell to fund the project. I'm really wondering what this manifold is worth and seems to be fairly complete for what it is. All linkage and studs, etc and looks to be in good shape overall. If anyone could fill me in on what's it's worth or If anyone is interested please let me know. I'm looking for a set of coilovers that I would consider trading these for. Thanks for the help!

Hi, My plastic choke cable sheath is broken. The cable inside is fine. Does anyone have any suggestions for alternative replacement sheath? All the Z car parts houses sell cable and sheath together which I don’t need (and is expensive). Thank you. Howard 1974 260z

While taking my manifold for resurfacing and replacing new bolts and screws, i discover 6 metal tubes from the former air galley that were about to fall inside. Will i need these tubes further or should i dump them? Any advantages on installing the emission parts back?

Hi Everyone, I have an Austin 1800 Mk1 automatic, the car is running great in that it idles fine, starts fine and does not stall.. ever.... the issue I have is that under load is just seems to be bogging down a bit, it also struggles a bit going up hills... cruising along at 80kms per hr it is perfect... sitting on 100kms on the expressway it seems to be making a strange sucking sound and bogs down slightly when I put the foot down to overtake etc.... It has new oil, new spark-plugs, a Scorcher electronic ignition (https://performanceignition.com.au/p/scorcher)... new air filter and oil filters... I do also run flashlube (https://www.flashlube.com/en/products/…

Hi: I've been driving my car and adjusting the jets and checking the spark plugs after my first attempt at tuning the 3 screw SU's. When shifting gears the RPM will sometimes not drop and I have to blip the throttle to get it to go down. I have my idle set at ~750 rpm and timing at 10 degrees. My plugs show I'm running very rich and I'm four turns down on the mixture for each carb. Would the stuck/surging idle be a mixture issue, or would that be a mechanical possibility somewhere in the throttle chain? I did sync the carburetors at idle and at 3,000 rpm. Thank you. Howard '74 260z

Howdy, Anyone have a compatibility list or someone that sells carburetor hardware, (screws and springs and such) for round top Su Carbs? I contacted Ztherapy, but they dont sell hardware out by itself. Been kinda scouring around online, and I cant seem to find anything... Regards, Rama
