Slinky Dogg Posted March 27, 2013 Report Share Posted March 27, 2013 I'm having trouble finding it??? I would really appreciate it and il post pics soon!!!! I'm keeping this b210 for life Quote Link to comment
datzenmike Posted March 27, 2013 Report Share Posted March 27, 2013 Look on the side of the intake just below the carburetor on the driver's side. There is a smaller manifold bolted to the main intake and this contains the EGR and the PCV valve. The EGR is mounted to the front on the smaller manifold and will have a small metal pipe joining it the exhaust below it. It's very possible that someone else has removed this small manifold on the side and fashioned a block off plate. to cover it. People think that by removing the EGR that they will somehow find some extra hp. Quote Link to comment
Slinky Dogg Posted March 27, 2013 Author Report Share Posted March 27, 2013 Oh snaps I think that's exactly what happened, it's has a bolted plate on it, I'm gonna put an egr on, how about the egr solenoid, what do I do about that? Quote Link to comment

People think that by removing the EGR that they will somehow find some extra hp. It may also have been removed to run a Weber carb. On the A series manifold the EGR sits to high and hits the Weber, at least with the 2 piece adapter. I don't know on the taller adapter if it would clear. Slinky, I have a 1974 FSM. I'll see if I can get a scan of the relevant page(s) later tonight when I get home. Quote Link to comment

Sierra Posted March 28, 2013 Report Share Posted March 28, 2013 Here is a pic of the most basic EGR setup. I got them from Datsun 1200 tech wiki website: Here is an article that will explain more abou the EGR system: http://datsun1200.com/modules/mediawiki/index.php?title=EGR Hopes this helps Quote Link to comment
datzenmike Posted March 28, 2013 Report Share Posted March 28, 2013 All gas engines produce varying levels of oxides of nitrogen. This happens under extreme peak temperatures and pressures inside the combustion chamber. What was found was that if you dilute the air fuel slightly with inert gasses (that should read air without oxygen, exhaust is perfect for this as the oxygen has all been burned with gas) the peak temperatures drop and oxide formation also drops. The NAPS system does this two ways. Dual plugs shorten the burn time so there is less time for nitrogen to mix with oxygen and the dual plugs allow a leaner mixture to still burn when more EGR is used. An advantage of EGR is there is a reduced risk of pre ignition from a cooler combustion chamber at normal speeds. In all cases, there is NO EGR at idle and full throttle... so effectively, wide open throttle performance is unaffected. A disadvantage is that if the EGR valve isn't cleaned every 30K it can stick slightly open and this would be a vacuum leak which would adversely affect idling. Quote Link to comment
