Ok so I decided to go single, and I know that the iac was hooked up to the stock twins. My question is where do I hook the iac valve upto now that I dont have the twins on my engine.
1jz iac question
- Thread starter wornoutsupra
- Start date
Some people just put a breather filter on it. Others put a hose from the iac pipe to the intake pipe before the turbo.
ok, well right now I dont have it hooked to anything. It is idling around 2k, if I put a breather on there, will it bring it back down to normal idle around 800?
not necessarily. you might have a vacuum leak or something else. Plus putting a breather filter on it is just going to prevent dirt getting into your intake manifold/engine.
Block it off. crack your throttle body open. or reroute it into the inlet. If you put a filter on it, it WILL cause a vacuum leak(causing it to idle at 2k). My buddy put on a rubber block off then drilled a hole in it, giving it a slight leak to idle at 1k
Mine idles at 800 blocked off with a aluminum plate I made. I just cracked the TB enough to cause a leak. Now that Proefi can Control it, I put it back on, to route back into the inlet, so I can tune cold starts etc
