I have a 1990 Eagle Talon AWD turbo 4G63, I had the chrysler mechanics do a head gasket because it was too cold to do myself in winter. I guess the Mechanic put the cam angle sensor in backwards(wires down) I need the proper cam angle sensor setup and timing.

1. If somebody could take a pic of the cam angle sensor on the inside with cover off (of the disc with the grooves in it) when the engine is TDC of power stroke for #1 piston of their cam angle sensor and post it I would be eternally grateful.

2. Also just want to double check my timing with you guys from my Haynes manual. What wire do I ground out on coil packs to set the timing, cam gear? If I run 12 psi boost, then pump it up to 30-40 psi do I have to retard the timing so I don't get pre-detonation?

The mechanic that did my car said he went through all the sensors, I have no idea what he did to it? He did a rush job, the bracket from cam angle to throttle body was overtop the cam, crank sensor on an angle too, have a leak in my turbo oil outlet line and who knows what else.

3. Also, my engine is still stock, on the top of the throttle body there are two 1/4" vac lines, one is black hose with green dotted line (on top rear of throttle body towards back of car) and the other hose is a black hose with red dotted line (on top front of throttle body) Is this right?
 
But it runs with the disk inverted and not with the correct position.
With everything set correctly, the engine runs really rough, it doesn't makes sense. I will try all positions - CAS and disk correct / CAS correct, disk inverted / CAS inverted and disk inverted / CAS inverted and disk correct... Nothing makes sense on my engine
This may be an ignorant thought but the CAS does both cam angle and crank angle, right? So if the timing belt is off a tooth or so there is no correct CAS setting. Have you checked the valve timing?

The only other thing I can think of is a spark plug wire mess-up. Doesn't seem likely.

Yes! In fact I times the engine and changed the belt with it outside the car. Once inside and with alternator and belts already there, I've removed everything to check again if the engine was correctly timed (after already tried to check it with a stick on cylinder one and checking cams).

The engine is now running, all summed up I have changed spark plugs, however the ones I had before were new so I wasn't getting there... Even they had spark indeed, but I don't know why they don't spark correctly. The engine is with my old Miata spark plugs 😂.
Now the only problem is the idle surging.
