Hi, i have a 76 280z that i just had smogged a few monthes ago, and i think it might be the last time i smog it. you have to smog your car every 2 years in CA and by the time i have to smog it again in 06, the car will be 30 years old, and hopefully smog exempt. my question is whether its posible to get rid of some of the smog stuff on the engine to make the compartment look better and maybe gain a little HP in the process. I've seen some 280zx engines in 240s that have had smog stuff taken off, and they work fine, and look great. im just wondering what you guys think of all this....anyway, thanx as always!!

ouch...no replies....i guess its not too important, oh well...

I'll help keep this on top. I wonder myself. Can you have the reliable power of the Electronic F.I. without that spegetti mess of tubes, wires and diaphrams? Do you benfit from EGR? What needs to stay and what can get lost?

Part of the problem is there just aren't too many 280's on here. There was a poll maybe a year ago and it seems like there was something like 12! Probably a lot more now.....

I know you can eliminater the FPR and the EGR, as I disconnect mine at autocross and it runs beautifully. I usually forget to hook them back up and....come to think of it--They are still plugged now! Be sure and plug the hoses if you disconnect something. Nothing will make your car run funnier than a vacuum leak. Probably wouldn't run too well without the air control valve (I forget its real name) (sits above the TB and is connected to the valve cover vent and also has hoses that bypass the butterfly. Mine was faulty and while I can't remember exactly what it was doing, I seem to recall it not running too well. It could probably be simplified. It talks to the 'puter, but I don't think it necessarily needs engine air. I think you could lose a couple hoses there and it would still do it's job. Let's see, what else. Did you have an A/C? If so, I guarantee the throttle accelerator is still installed. Vacuum diaphram with a hook coming out of it that hits a little plate on the linkage. Gonzo. There are a couple hoses that run from it all the way around the engine bay to stuff on the passenger side. Rip it out! What else....... Just start plugging things. If it doesn't run, then youprobably need it!
