Posted December 24, 200420 yr comment_106168 Any setup suggestions or whatnot? I may consider switching in the future (my efi is very quirky).thanks Link to comment https://www.classiczcars.com/forums/topic/14437-what-all-would-i-need-to-switch-my-280z-to-su-twin-carbs/ Share on other sites More sharing options...
December 24, 200420 yr comment_106170 As these cars age this will be more and more the case. Find a early Z ,from '70 thru '73 for a intake manifould get all the linkage . The '73 could have the flat tops , DONT get these but the intake and linkage from the carbs back is good. The intake manifold is a direct bolt on and think about new needles , SMs, for the carb. because of the added CCs of the L-28 . The air cleaner from '70--'73 is the one . It has horns inside that are tuned for the proper length for the ram effect. One more thing get the bake-a-lite insulater ''gaskets'' that fit between the carb and the intake manifold. The correct ones are about 1/2'' thick. 3 screw and 4 screw SUs perform the same so either are good. I have a extra set of carbs if you need them . I see them on ebay all the time. Dont wait too long because like you people I think more and more are going this route. Get the choke leaver and cable to.

December 24, 200420 yr comment_106175 If you had a choice of parts , try and get a n36 manifold from a 260z and use the 70-72 su carbs , and get a euro balance tube. Also depends if you want to run emissions or not. The center linkage is not the same to all the types of su carbs that were made between so if it doesn't come with get with z therapy. I would check with hybridz to see what issues if any you would have with removing the ecu in the car, assuming it has one. You might have to do some wiring for the temp sensor and depending on where you live you might have to use older style thermostat housing for warmup line for the early manifold. Good luck .
