    Default Wanting to Carb swap my L28? Is this a good deal?

    I new to the Datsuns but admired for a long time, my FI is HACKED up by the previous owner. I always liked mechanical over computers etc. I found these is this a decent price for a set up? even if they need rebuilt? Datsun 260z Twin Hitachi Su Carburetors w Manifold Heatshield | eBay

    Pros and Cons of Hitachi's?

    I have the n47 head, car is a 77 280z. Thanks for any help. I already like this forum more than the first one i joined! Lots of info.

    That may be a good price but they aren't the carbs you want. Almost everyone uses the round top carbs. Earlier vintage & very adjustable. Bruce at ZTherapy would be a great person to advise you. You don't want to end up with nice shiny carbs w-worn throttle shafts.

    I agree with Mark. If you are going to ditch the injection, you will want to use the '70-72 carbs. The difference is not just performance, but drivability. Unless they are extensively re-worked, the '73-74 carbs are prone to all manner of drivability problems - lean surge, hard hot start, vapor lock, etc.

    I wrote a tech article on this topic years ago, but it should still be current for the most part.

    We supply the early setups for injected cars every so often. Guys are tired of fighting the de grading injections and just want to get in, hit the key and drive away.... Easy deal

    The guys at Z therapy are truly top notch. No kidding. You cannot go wrong there. SU's are fantastic carbs. They are very close to set it and forget it. When healthy they can keep a Z purring along for a great long time.

    Best of luck

    I have a 260 with early SU's and a 280 with FI. An FI system in proper working order is nice for a street Z, but I love the simplicity of my SU car. It fires right up and runs great. If you go with a ZTherapy setup, I'm sure you will be happy. If you ever decide to add a performance camshaft, the stock FI will be very unhappy while the SU's will work great with minor tuning.

    If it's like years past, It's $5 to bring your car in or a whopping buck to walk in. Well worth the price of admission just to get to see me....... nyuck nyuck
