2G Throttle body questions with pictures

[djseclipse]

Long story short. Bought my old gst back and was performing a blt. The previous owner installed a magnus smim and there were leaks everywhere. I also have shaft seal leaks and will replace with 74mm s90.

They only have 3 bungs on the im. Bov, pcv, and fpr. Is this correct? Only 2 of the 3 small nipples on the tb remain with a hose looped to the 2 (see picture) is this correct? And what is the 2 short black things on the bottom of the tb? (see picture)

The car has horrible idle and misses only at idle. All issues seem to come from whoever installed the smim as the car was very sound before I sold it. Couldn't get blt pass 7 psi testing from hot side of intercooler.

Thanks in advance for the help

The nipples on the IM can be routed any way you want. I have one going to my brake booster, one going to the BOV, and one for other crap like the boost gauge and MAP sensor.

All 3 nipples on the TB (one is missing on your TB) are typically blocked when using an aftermarket IM. If the little ball is missing, that may be the source of a leak. I can't tell if those are blocked or not. Either way, they should be blocked, so make certain they are.

The 2 short black things on the bottom are flexable wire holders. You can bend them out of the way, bend them to hold wires, or remove it.

Thanks so much! Yeah there is no ball in the nipple that's missing. I can't believe the car runs as stout as it does with all the boost leaks it has.

One more question. The magnus im has a 65mm tb opening. Will a 70mm s90 tb fit or will I have to open up the magnus more?
