  1. Teflon suit on - Check Here goes... Ok, first post here and relatively new Z owner (1.5yrs, 260z 2+2 Auto). The car has weber 32/36 conversion with all the smog stuff removed. It runs decently well, but is rich at idle and takes a bit of cranking (6+) to start if it sits longer than 2 days. It doesn't have a lot of power but I don't really know the baseline. The engine runs smooth, and it definitely pulls ok, but I think it's probably in the 75% range of what it could do if tuned properly. It has a resonator and catalytic converter and original exhaust manifold. I recently switched to non-ethanol and it seems to like that a little bit more, slightly easier cold-starting, a little less missing and oddness. The engine/exhaust note isn't anything I'd brag about and it's more along the lines of a chill cruiser (partly probably reinforced by the auto transmission). Finally, the webers just don't look right in there and I just really love the original look of the SU's with the orange airbox. Sooo... I picked up a few Flat Tops (a NOS front, and a used pair with an airbox) and a refurb kit, thinking I would keep it correct for the year, but without re-configuring all the emissions stuff. I'm looking for some advice here from folks who have experience with the flat tops and don't hate them but that said, I welcome all feedback. My basic question: What's the minimum viable connectivity with the emissions deleted? Do they NEED vacuum? Do they NEED coolant? Do they need the temp control stuff and the anti backfire stuff? Does anyone have or know of good HSM for the 260Z fuel system? The HSM from Xenon is better than nothing, but the scan quality is so low for the fuel system portion it is hard to read. Thanks for all comments and feedback, -j
  2. Hi, so I am in the process of converting my car from flattop to roundtop carbs. I have the intake manifold, balance tube, and carbs for both setups. The engine is an L28 that came with flattop carbs on it and a mess of hoses and wires. I need help identifying hoses and figuring out what I don't need, etc. I have removed the flattops and their balance tube, then bolted on the balance tube for the roundtops to notice that there's no spots for some of the hoses that are there. I have pictures attached. The next thing I noticed is the roundtops won't fit on the manifold and need the larger bolts of the manifold that came with them, so does this mean they won't work on the n33 manifold? Next, there's no spot for the coolant hose, does this mean the roundtops don't need coolant, and if so, how would I remove this hose and block it? As you can tell I am pretty clueless but thanks for all the help!
