89 Turbo build from 85 GLS-SE
 

What pieces of this puzzle work? I discovered the intake manifold is different at least the lower is, anybody know about the upper? I assume it is different as well. What other components will need to be swapped? I think I remember something about the Oil Pan. It has been sitting at my mechanics forever and he is now making the time for the 'side' project. Anything I can find out in advance would be helpful.

I have a street ported engine with no miles on the rebuild. We are leaving the turbo off for now to make sure we can get it going again first, will look into adding the turbo someday...

It has been a long time, I am off to peruse this site again now. All advise is welcome!

Thanks!

You need to be clear about what you are doing.

Are you putting an S5 engine into a GSL-SE?
