92 sr20det turbo help

[speedracermage]

hey i have a 89 240sx with a 92 sr20det motor. i bought the motor and had it in my 92 then i bought an 89 had to do some custom work with the power steering lines.

my car ran fine. i love the motor. out of no where a week ago, my car went to pieces.

the car got a high idle out of no where then. would turn on but would die after gas is applied and i get a small highpitch noise as if air leaking. but all vacuum lines are intact.

i have some oil blowing out of the back of my exhaust and my turbo is almost non existant now (as far as boost or even functional).

my other issue is im told that my intake manifold gasket as well as my collector gasket have blown.

can anyone help ???????

this is my daily driver and i need to get it back on the road.
