Hey guys newbie here. I purchased a 73 240Z that came with round top carbs and a n46 intake already on engine. I have a n33 intake manifold I want to put on, but how would I go about getting it to work properly with all the emissions equipment? I have heasrd this and the n36 flow better so I'm polishing my n33 to put on for a litttle more go. Any help is greatly appreciated. This is my first Z and I'm in love with it.

Welcome to the site. First thing , why are you concerned about the emissions equipment. Go with the N36 intake from a 260, plug the air gallery tube on the exhaust manifold. You can find the plugs at NAPA. Try to find a 70 or 71Z balance tube.

The Emerald City Z Club is located in the Greenville area, nice guys Try looking them up.

I didn't answer your question. Do you have a FSM. If you don't you need to buy one on ebay.

Thanks I will check them out. I got the intake with the car, thought I might use since I read it was better than the N46 far as flow. This is my first Z. If I buy any intakes it will be a set of triples and a bigger cam. Thanks for the info
