well I was wondering what would be a safe PSI to run without any type of engine management I was thinking something like 3-4 PSI should be just fine untill I can get some sort of engine management. I know a few guys that are running over that (in other cars) with no management and aren't having problems...

well I don't know what turbo your running.
but I know that it would depend on which turbo you run. A t25 or T28 at 5-6 psi is a good amount of boost. You would still need something to add some sort of fuel when you are under boost.
If you install the turbo, just make sure you have everything. I think the BP can handle way more than 5-6 psi with good tuning and stock internals.

You might wanna check your stuff there. O2 sensor output is supposed to go from full lean to full rich when at low RPMs without load.<a href=http://s87170394.onlinehome.us/><img src="http://s87170394.onlinehome.us/ente_anm.gif"></img></a>

hey Tweeaks I wouldn't run the turbo with no fpr and boost. I am not sure, but at highway speeds would there be a chance of running lean.. especially if your car is running like 2800 rpm at like 70 mph ..
anyway
Yeah MiK only thing I don't like about autometer o2 gauges is that they bounce all over the place. It does it in thegoldpro(ben)' car and my friends crx.
