What should the idle be for a streetported engine?? I don't know if it would just be the normal seven-fitty or what?

My streetport idles a little lower - like 675. I wish I could get it to idle at 800-850 though. My 6 port actuators are removed completely as well though - probably not a good thing.

Hi guys, with a street port 6 port engine I have seen a 800rpm idle to be very satisfying. If your having some problem trying to get your idle up to 800 adjust your idle cam. When the actuators are pulled out, u will notice a decrease in low rpm torgue, (car get's a little lazy) for everyday driven I like to leave the sleeves on. What I do with all the cars I work on, is to make sure that the actuators are working correctly. when this is done this way, u will notice improved low rpm torgue and mid range power. I have taken a 1986 Rx-7 street port 6 port to the dyno, with stock ECU some 720cc secondary injectors Racing beat headors, 93 Fd fuel pump, and before the actuators kicked in about 4,800 rpm the car mas making 120rwhp, as soon as the actuators kicked in, the engine went up to 142rwhp. With the sleeves on the car feels very responssive at low rpm. Im sure the horse power on a 6port could be much higher, but u will have to look into higher compression rotors after market fuel managment etc,etc, i hope this is of little help..
"if it aint a rotor your just waisting your own time!!!

you should still be able to get a good idle at about 800.
mine is a little rough sometimes but ive got my ports wired open.
i know that its a turbo, but the idea of a good street port is that you can maintain good idle and low end power and dont have to sacrafice anything
