I finally got my conversion complete from a 1981 280zx turbo to a 1978 . It will run and idle but when i give it gas it bogs down, Also it has gotten to where it takes about 30 seconds of cranking before it will start, Will Start right up when cold but seems to be running rich, any ideas where i need to be looking? Another thing is I can hear turbo spool up and when I keep slowly idling up it will rev but not showing any boost on guage.
