i dont remeber what their actaul name is but the secondary throttle bodies on s13 ka24de motors, they cause vaccum at certain rpms to keep the torque up, they are located right at the ends of the intake runners beofre they meet up with the head. i m getting pdm cams, and then later this summer i will go turbo and they say to get rid of them for turbo, and the s14 ka doesnt have them so with the increased breathing of the pdm cams i might as well get rid of them now while i ahve it all apart.

ok that was a link, but it didnt tell me anything new, that i had read before, i need to know how to fix the idle if it does mess the idle up, i was hopeing someone had done this and not turboed the car yet...........

did you CLICK on the LINK?

this mod does not have any affect on idle. your idle speed is controlled by two things:

throttle plate
Idle Air Control Valve

as long as you don't mess with those (i.e. take the IACV out and forget to put it back in...basically impossible) you won't have a problem.

ok, there was a idle control thing that bypasses the butterflies, and there was one more that has a solinoid on it, i was thinking one of these could be removed, the link said the idle was lumpy, but it didnt sound like the guy had his run after he did the mod..............

I don't know. You'll have to ask someone who's done this mod. First, I've never had a KA24DE. Second, this mod sounds like a worthless waste of a Saturday. I guarantee there are better things to do.

i guess, its worthless to you but i m keeping the ka, i m getting better cams, i need it to breath better, so i need to get rid of them, also im gonna go turbo, and i already have my head off while i iget a new one so i got the intake mani off, and i d rather do it now while i have it off so it takes 15 min instead of a saturday afternoon..........i also said i wanted to know if any one had done it, so you really cant help me.

thanks anyways,
p.s. i got alot of other things to do but this is at my top till my head comes...........my opinion

sounds like you're doing it then. by the sound of your first posts, it didn't sound like you knew what was going on.
