taking tb off:)

[DARKTALONTSI]

i did a boost leak test on my 2g tsi and found out my tb was leaking air and changed pitch when i moved it so my shaft seals are bad.....i wanted to know if there is anything else i should do or replace on my throttle body since its going to be out of the car anyways to do everything at once...other common seals known to go bad or what do you guys think about the fiav block off worth it or no?

The gaskets, i would go ahead and get one of these spacers for the intake manifold:

EXTREME PSI : Your #1 Source for In Stock Performance Parts - Magnus Heat Barrier Intake Manifold Gasket : Mitsubishi Eclipse 95-99

Works great

or if you wanna save a few bux
eBay Motors: 95-99 Eclipse gst-gsx Talon tsi 4g63 PX3 Intake Gasket (item 230314462952 end time Jan-13-09 20:47:16 PST)

I wouldnt block off the FIAV, i would use the bypass plate to save the ISC

You're in socal so the fiav doesn't do much for you. You can do the blockoff (leave the isc alone though) and your tb will be a little cooler but honestly, at your mod level it's not going to do anything worthwhile.

Just pull that guy off and swap some new shaft seals in there and you'lll be fine. FIAV is just for startup and if it isnt giving you problems, dont worry about it.

Just replace the shaft seals and the gaskets on either side of the TB. And there is no need to take the intake manifold off.

Just pull the tb off as stated and change the seals.Its simple as long as you remember how it goes back together.I suggest getting a manual for the car in case you never took a tb apart.Or use vfaq.It shows you how to do it step by step.
