Hello rotary gurus!

I am in desperate need of guidance…

I have had my engine rebuilt for my 93 FD and had some corrections done to the street port (former owner did a hack job). At the same time I have changed the turbo as the old had melted the turbine wheel - old turbo was reused from a drift car with anti lag and was apparently melted before mounted on my car.

i have installed the engine, checked and rechecked ground, vacuum lines, fuel, everything.

the car starts but idles around 4k rpm. When vacuum is pulled from MAP it decreases to 2k with very pour idle.
there is no throttle response and it seems like the car is drowning.
when TPS connector is removed there is no significant difference.

I run single turbo PFC and the car ran fine before rebuilt.

the car of course needs adjustment after change of turbo but I would expect it to be able to idle somewhat decent

next step is to measure TPS and ensure it is within spec once I have sourced the test pins.

any suggestions on what to check? I am clueless as I don’t think the turbo and port would have such big impact and expect something else
to be wrong.

Thanks!
Mike

You have air getting in that shouldn't be. You need to find where that is coming from.
