I have a question about performance and idle speed. I have a 78 280z, runs great, just replaced the one part it seemed to need to enhance its performance which was the lower pcv hose, the old one was crap. Boy what a difference the new one made... However, once I replaced it the idle went up from 800 to about 1000rpm. And I noticed the car's throttle switch didn't kick in to send it to full enrichment for full throttle application. So I lowered the idle to about 750 or 800rpm with the engine up to temperature of course.. Then I took it for a spin and it blew me away, I mean it threw me back in my seat, the performance was 1000 times what it was at the previous idle setting. My question is, how does the idle screw adjustment effect the idle? Is it adjusting airflow or does it control fuel flow somehow. I assume it's air... Any input from you guys would be great. Would love to know more about what's happening here.... -- Jeff..

Ok I am aware of the popular L28/L28ET swop, but if I want to keep the orig L26 engine is there any proven ways (not to cost prohibitive) that can noticeably increase performance (say hp & torque up by +20% ?). Only mod I have made so far are early 240z carb's..Are stroker build for L26's available/worthwhile ? Apprecaite your thoughts.
