95 GST motor problem and questions

[darkmajesty06]

Alright,

I just bought this 95 gst past night and i have no idea on motor upgrades other than a fmic kit.. It has god aweful body kit, wheels, horrible paint but the motor ran real solid till today.

So here is a pic of my motor, could you please point out any aftermarket items or anything that looks fishy?

What is that big chrome thing attached to the turbo?

In thid video, could you tell me if its regular lifter noise or if i may need to rebuild the head?

I had a oil change and have shell high mileage 5-30 put on.. Was this a solid choice?

My bov has the threads stipped where it says hard soft.. Can i just use sealer on it or do i need to purchase a new bov?

Thete is a whine(ever stood by a power transformer and heard that buzz it makes?) above 2590-3000.. Its coming from outside and driver side. It stops below said rpm and always make sounds around and above said rpm.. Any known issue on this whistle/low pitch sound or do i need a real diagnostic on it?

I dont hit boost until around 4 grand.. Is this normal?

What octane should i use in the car?

Isnt the bov suppost to release excess pressure whenever in boost? Mine wont make the whise until around 5k. As stated before, i cant adjust it because the thread is stripped on the adjusting hole.

Car just needs to crank but not fire, right? If so, ill see if that compression tester i bought works tomorrow. Also, my car has ecmlink installed. i just need a data wire to hook to the labtop.
