Its an 89 Gt
306, twisted wedge, TF R intake, 42# injectors, 80mm mass air, 75 mm T-body
And its a twin turbo project.
8.5 copression ratio.
This is my first project car so I dont know as much as I wish I knew about them.

Anyways, its starts up good, and idles just fine, but the warmer it gets it starts surging, and blowing smoke, until eventualy, it dies.
I have replaced, the O2s, the Tps, and the spark plugs.
What do I do now?
My old stock throttle body had a hole drilled in it, should I drill one in the new t body?
I was told when I bought the car that the cam was stock.
But I have to wonder if maybe its an E or something.
Thanks for your help

What color smoke ? Black?

42's Are Huge for a NA setup like that, even for the time being. Too much fuel will kill your rings, Quick with that much fuel. Waay too much fuel im sure, what do you have the Fuel pressure at?

Id say get it on a dyno and get a tune on it..

yeah, black smoke,
pressure right now is about 30-40
I know 42 is alot for a na setup,
but there has to be a way to make turbo car idle.
It idles fine until it warms up.
Im wondering if maybe its the idle control thing on the Tbody.
It sits right by the turbo and the heat may have damaged it,
or it may just be old and worn out.
