? about butterfly removal

[podboy3]

when you take the butterfly out of your intake manifold what is the best way to plug the hole at the back of the manifold.
   also dumb ? but on the underside of the intake manifold there are four tubes that looks like rubber hoses hook up to them, what the #### do they go to and can i just plug them with a piece of rubber hose and a bearing.

try bubblegum <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> really though try sometype of filler (exact names are slipping my mind) make sure the filler can stand up to the underhood tempratures. Goto a car or even hardware place and look at metal filler.

Just out of curiosity, why would you take the butterfly out of the intake? &nbsp;Are we talking the throttle body metal piece that moves when you hit the gas?

[LanceS13]

nah...there's a secondary butterfly in there somewhere. &nbsp;Taking it out is supposed make the intake less restrictive or something...don't know enough about it to say anything for certain, though.

[chickenmanq]

Hmmm, maybe I'll start looking for that.

[podboy3]

yeah it is supposed to work by taking it out, i am not sure of the gains and this is the way i got the intake so i figured what the ####, i guess if bolted the bmp or what ever it was attached to back up and put a ball bearing in the hose that would work, unless the bpm is supposed to be hooked up no matter what. &nbsp;

Please find who did that, so we can all laugh at him. The throttle body is a valve, leaving it open would basically put your car at WOT the entire time it was running. That's probably the stupidest fucking thing I've ever heard of and you're not much brighter for believing it.

For the SCVs, leave the set screw in place to seal the middle hole and tap the outer hole where there rod exits the manifold, install a bolt.

The four hoses below the runners are the PCV system, tied into the PCV valve through a steel hardline.

The intake manifold houses a swirl control valve in each passage way of each cylinder. During idling and low engine speed, the valve closes to increase the velocity of airflow to each cylinder. This also promotes fuel vaporization and produces a swirl in the combustion chamber.

SCV's (Swirl Control Valves) are only found on OBD-OBD1 KA24's. It's really only for old smog emissions and they aren't needed. The KA will have much more high end power with out them.
They came on 1989-1990 SOHC's, 1991-1994 DOHC's.
It's about a 6HP gain to the wheels removing them from the manifold, most people don't bother removing them, but rather use a 95-98 upper manifold half instead...
It was used to increase throttle responce on the low end, also to increase it's atomization to burn a better A/F ratio when the engine is under load especially since Nissan tuning on USDM's sucked back then, tunes are a bit on the rich side of the ratio. - BigVinnie

Holy flashback batman. Informative none the less.
