I finished a 86 Regal Limited swap over the winter. The car came with the 307 Olds engine. This was a nice clean car that I couldn't pass up. I already had a grey limited "pillow back" interior and a complete drivetrain.
The swap is not for the casual weekend wrench. To do it correct, there are many turbo specific parts that need to get changed. Here is a short list:
Inner fenders
HVAC case
engine harness
fuel, vapor and return lines
fuel tank
frame pads for the engine mounts
Steering gear
dash harness
speedo cluster
I removed the entire front clip and lifted the body off the frame to run the fuel and return lines. I used factory repro lines from Inline Tube.
I removed the dash, swapped the dash harness and cluster over to turbo parts.
I definitely did it the hard way, but you'd be hard pressed to find anything that doesn't look like the factory did it. None of the tasks were hard............just lots to do.
