See those gold screw holes next to the throttle body? What screws there? I'm confused because my car doesnt have anything to screw there.

 

Maybe a flux capacitor

 

Just kidding, have no idea. In for results

 

It's where the original intake setup snapped into place on my car. No screws involved.

 

My memory is foggy but I think that those were used to secure a wiring harness(es) in place that ran over the manifold? I don't remember the intake connecting to the intake manifold on those points.

 

^ sounds about right.

 

there is a wiring harness snapped in between two gold bolts in the little black hole, but these have screw grooves. weird.

 

I dont think anything went in those. Remember the engine was designed for multiple cars / platform applications. Those might have been for a Cavalier, Opel, Saturn, etc.

 

looks like a reference photo, peroid. Wheres the little nipple under the TB for the brake booster? This is why I think it's a generic reference missing a key part any NA ecotec requires. I think the op was just bored and trolling around for some attention.

 

on the l61, at least the one I had, the brake booster hose goes in the drivers side of the manifold. there's no nipple by the tb.

answering the op if he's not trolling, there are only 3 or 4 of those screw holes that are used, two for a wire harness and one for the dipstick.

 

Good point. I'm thinking about the 2.4L IM that's on my car now, lol. Good call though.
