remove and block off the sub zero system, even mazda agrees with that one, it's useless, any one who knows will agree.

If your air pump is gone did you remove the air control valve as well? What air pump hole are you speaking of?

The EGR is entitrely emissions related and can be removed if you know how.

OMP stands for the Oil Metering Pump, S4's have a mechanical one and S5's have an electric one, they squirt oil into the engine to cool and lubricate the rotors, you can remove that but you will have to run premix and dump oil in your gas tank every time you fill up.

Search around for "emissions removal" and you'll find all of this info.

the whole i have blocked off is the one that comes off of the air pump through a hose which i would think is the air control valve on the left side of the engine? Also will i encounter any problems with block off the egr valve?? My car seems to run better now untill around 3600 when the 2nd injectors come into play any ideas on what might be causing this?? i want to invest in a safc but will have to wait a few weeks to get one? will this cause me any problems until then the car still runs good it just hesiates alot like i said at 3600 rpm thanks for your info

EGR VALVE - this valve injects exhaust gasses into the combustion chamber under certain circumstances to lower combustion temperatures to prevent the formation of NOx, which is a greenhouse gas. The EGR valve doesn't really affect performance one way or the other, but a bad one can make for a lousy idle. To remove, install a block-off plate and cap the vacuum line.


And thats the infamous 3,600 rpm stumble, search "3600 rpm stumble" for more info, thats really common in the rx7s, I know my the next upgrade to my Rtek 2.0 is going to correct this stumble, though I never noticed it on either of my rx7s.

Hope this helps.
