Default Throttle Body Hose

I just started my turbo build and was wondering where this nipple on the throttle body side should be routed too. Thanks

That's your idle air control valve inlet.You can leave it VTA, put a filter on it, or reroute it to your intake anywhere pre-throttle body.

I've always hooked up the IAC feed pre-turbo...
Does it not matter?
I've never tried to feed one boost...
It would make it far easier to route just teeing in to the cold side there.

I had mine on my old 1.6 right off the TB inlet pipe. She loved boost

They will leak boost if you don't put in a check valve if running them VTA or pre-turbo. Mine is just plumbed into the tube going to the TB.
