Manifolds with EGR bung
Are there any NB manifolds still in production other than the FM and Blip Speed Motorsports (Max G) that have EGR bungs? I'm looking to maintain emissions compliance, but am having trouble stomaching $1k for the FM stuff.

Are you no longer running a megasquirt? A megasquirt has no provision for controlling a EGR valve.
Are you certain the EGR is required to pass emissions testing where you live? |
Note that most aftermarket ECUs don't implement EGR, so unless you're running a low-power turbo with a pulse-lengthening fueling solution like FM's Voodoo box, you'll find it difficult to actually run EGR with a turbo.

You can tie into the exhaust after the turbo and before the cat.
Avoids the turbine inlet pressure (TIP sometimes double the boost level) working against the EGR valve. If you must run EGR this is the way to solve the TIP blowing the EGR valve off its seat. "No inspections" I'd leave it off until it became an issue. The turbo and any non-CARB parts will defeat any emissions compliant goals anyways... The only truly effective way to skin the emissions cat is to keep ALL of the original crap in a box and fully revert to stock as required. Check out SOH's threads. He reverts every two years. |
