I currently have a Holley 4 barrel setup on my 73 240z. I am selling my holley and going to go with some su's. Is it okay to use my n33 manifolds? Also, what should be blocked and/or setup as far as the emission control stuff. Anyone have any pictures of a properly setup su carb install? Also, do you guys think the ztherapy carbs are worth the money?

Well, what is value worth? To me they have alot of value because I included the support from ZTherapy, the warranty, good looks of the SUs, Video included, the available mods they did for me, the phone time, I tapped into their experience and knowledge of Z-racing, oh and their new stickers are well worth SU-money!

on the topic of emission control, I have all of that neat stuff cluttering around in my engine bay...how much of it can I get rid of? all of it? if so, do you just plug off the holes, etc? thanks

Craig,

You can use "Search" button here and put keywords like "air pump" or "smog pump" etc. It will bring you a lot of threads on emission devices issue.
