Converting an '85?
Can an '85 GN engine be converted to a turbo '87? If so, is it worth it or should I simply buy an '87?

IMHO, get an 87. You don't want a mongrel for a showpiece, much less a DD to try and keep up with parts for different years. Besides, I don't think the block design is up to the power increase (someone correct me if I am wrong).
I believe someone makes an intercooler kit for the hot air years. Although I'm not sure how much work is involved. Good luck... |

Both the '85 and '86/'87 style blocks are essentially the same as their non-turbo counterpart blocks. See pics on this website. No differences. The 86/87 cars had a hole tapped for turbo drainback. But there is no additional meat for the additional HP in the motor. The piping/turbo/cooling/ignition/power steering switchover gets complicated for the swap. However, its been done many, many times. See our archives and the Forum archives as well as the website for more info. |

I was confusing the production 86-87 block with the Stage 1 block. My mistake. Even so, easier (at least for me) to go get an 86-87 model vehicle that is already set up and go from there. Many around to choose from. |

I swapped out my 85 engine and everything on it, from motor mount up and the engine bay harness and pcm. Can be done, but may be cheaper/easier to buy the whole car.

The early cars are a great value, however. |

I have a hot air that goes fast. If I knew what I know now I would get an 86/87 on the front end. The money spent on a hot air is alot cheaper than an 86/87 but you will more than make it up on improvements. An example is that I have to custom make a 3 inch downpipe which eliminates the turbo elbow. My 2 cents. Brad
