secondary air pump removel question
 

hello iam new to rx7 club i just go a 89 fc n/a vert and i want to remove the secondary air pump (has no cat and a cone air filter) the vacuum line goes to the air pump then it goes in to the air control valve then to the cat


so if i remove the air pump is it ok the have the vacuum leak at the air control valve or can i remove the acv all together

thanks jake

Do not remove the air pump on an S5 NA. The air pump supplies pressure for the aux. port (6PI) and VDI actuators. Together these systems are responsible for about 40HP.

This page has info (from the FSMs) on the aux. port system for both S4s and S5s. The VDI actuator is controlled similarly. The ECU energizes a solenoid, which directs air pressure to the actuator. http://mazdarx7.iougs.com/intakeair.shtml

you would have to your ECU chipped from www.pocketlogger.com to remove the OMP

thanks that helped a lot

You can remove the hose to the split air pipe (from the ACV). Just don't remove the ACV itself; it has a nipple on it that directs air from the pump to the 6PI/VDI actuators.

Without a chipped ECU, removing the OMP puts the engine into limp mode.

First thread I look at from illinois and its a fellow rx7 vert nice where you from man. I got a 87 vert not to long ago and i will be going the same route as you except i take the drift detour.lol Maybee in the spring we can meet up somewhere. Let me know what else you got in store for your 7 I'm doing the turbo drivetrain swap maybee together we can learn something about these vert's

iam pretty much going for autocross i want a roll cage very bad. i need to find a t2 diff then iam going to leave it for a while. save up for a swap not sure what iam going to do.

looks like both of us are looking for the same thing are you doing a turbo drivetrain swap as well
