Vacuum diagram

Can you tell me the P***** code you are getting?

First change the distributor cap and rotor.

Multiple missfire's are usually caused by the ignition timing being off or a bad coil(s).

It may also be caused by a bad catalytic converter causing too much backpressure. To test this hook up a vaccuum guage and let the car idle at 2500 rpm for 3 mins, if you notice the needle steadily going down throughout the test you need to check the exhaust system. Also a rotten eggs smell

in rare cases your cam position sensor or crank sensor may be off.

You may also want to check your PCV valve and filter and clean the EGR valve.

Check for a intake manifold or vaccum leake by using starting fluid sprayed on the hoses and gasket, if idle increases you have found the leak.

The vacuum would be needed for the wastegate, you would need to tee into manifold vacuum.
The oil supply is CRITICAL as well as return. Generally, you would tee into the oil pressure sender for supply and punch a hole in the pan for return.

You need to test and retest for oil supply to a turbocharger, their expected life without oil is about 25 seconds.

The most critical component to any forced induction system is reprogramming the ECM, more fuel at boost and less timing.

I would only use a synthetic oil and plugs at least 2 heat ranges colder.

Could you contact the manufacturer of the turbo?

You would have to buy a brass "T" for the vacuum lines and tee into an existing manifold vacuum line.

For oil you would have to buy a larger brass "T", and remove the oil pressure sender.
This tee would have a male thread same size as the oil pressure sender, a female port for the oil pressure sender, and a male or female port to run an oil line to the turbo.
You would want to use Earls braided SS line from the tee to the turbo oil inlet, the fittings should be steel not anodized aluminum.
The return line should run continuesly downhill to the pan.
Coolant lines for the turbo should also be Tee'd into coolant lines BEFORE the thermostat (supply line would be from the engine block, there is one plug in the block). You would need a return line for coolant as well. (You would tee into a heater hose for return).

Didn't this turbo come with all the tee's necessary?

Oil supply would come from the oil pressure sender in the block.

Vacuum would come from the fuel pressure regulator vacuum line.

You would use the supplied "T's" to get oil and vacuum to the turbo, yet keep the oil supply to the oil pressure sender and vacuum to the fuel pressure regulator.

Hello,

Here is the vacuum line diagrams for the EVAP and vacuum systems. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

There should be a diagram of vacuum line connections under the hood on a sticker?

I cannot find a diagram of the vacuum routing, but go to a pick and pull and find a 96 Corolla or Geo prizm and remove label or trace diagram, or take pic of engine.
