Default Egr delete wether I want to or not

1999 miata. Fm voodoo turbo setup. 49 state emissions car.

So, broke my egr tube from my flyin miata manifold while reinstalling it. It wasn't clearing the supermiata coolant reroute and I was trying to bend it to clear.

Regardless, the fitting is not coming out. So ill tap it and fill it with a pipe plug i guess. Not optimal, but is what it is.

Im running a stock ecu woth an old school fic6 aem piggyback for tuning.

Is there anything other than plugging both ends off that I need to do? Anything I can do to keep the check engine light off short of a standalone? I don't have emissions in my county, but the lights bug the hell out of me.

And yes, I searched. But holy crap contradictory information, dead links, and not much conclusive information that I can find. I also suck at searching.

Hopefully your install is complete and you're back on the road, but I feel your pain. I just mangled my 2nd EGR pipe trying to get it to fit on a car with a Cobalt coolant reroute kit. The FM support guy suggested I could just bend it a little and it would fit. After destroying the 2nd one and almost destroying my exhaust manifold I ordered the FM reroute kit which is shaped specifically to accomodate the EGR pipe. So now my $4,800 turbo kit has become a $5,500 turbo kit. I really think they should add a note to the page on the site that says "this kit is only compatible with FM reroute or stock coolant routing."

I did finally get it to work. I got a second EGR pipe and made a spacer on the intake manifold side as well as bending the EGR pipe slightly and putting it all together loosely and with the manifolds loose and the EGR finger tight and tightening it all up by working around the fasteners. It was a lot of fiddle ******* to get there but I did get there

Did your Cobalt kit come with their custom EGR pipe? If not you should give Moss a call. Their revised EGR adds loads of space. Pricey, but saves you the headache.
