So I just finished up swapping an 81 l28et into my 76 280z. Runs and drives but far from a smooth running car due to only having a downpipe haha. Using the n42 intake seemed like a good idea at first but I really didnt study up enough on it. Problem number one: the turbo blocks where the crankcase vent goes into the manifold. My solution to this problem was to just run it back into the J pipe, figured this was pretty much the same thing as before just without the little check valve and now it is behind the throttle. Problem number two: What to do with the other line I had running from the T connector, that was connected to the vent on the valve cover and airflow regulator, back to the j pipe. I ended up capping it off and didnt really see any change in performance. I guess my question here is how important is the airflow through everything? Does the air regulator actually need to be connected before and after the throttle? I think this will be much easier to diagnose after I get an exhaust on the car, but for now its just running poorly.
