1985 buick grand national

The magic G80. Can't go wrong, there.

Smoking is usually the turbo seals or the crappy plastic valve stem seals. New turbo fixes that problem, if not some new 100lb valve springs and new seals is easy.

If its fogging for mosquitos smoke, the motor should come out, but it doesn't sound like that.

Looks like a nice straight rust free car.

G80 Positraction was an Option on GN's. You could get the stronger 8.5" rear axle, but still only do 1 wheel burn outs, which is lame.

Other than add an intercooler, there is lots of potential in the '85 hot air cars. The cone K&N is a good start. A junkyard electric fan is another. Those two mods and its faster than every other Non turbo G-bodies with the same mods.

Can these be converted to 86-7 intercooled? I'm guessing this is covered thoroughly over on the turbobuick forum . . . was just curious.

Great find BTW! Enjoy . . .

Looks like a pretty straight car. If the smoke is pure white, could be a head gasket. Greyish or blueish smoke is oil burning. Comp 980-12 spings I've read are a good replacement for stock GN springs since you'll have to have em off to change the valve seals anyway. Unless they've already been changed.

^^Couple build guides for hot air cars in there. Most end up swapping to the 86/87 top end and intercoolers though.

The bolt flange on the turbo was square 4 bolt, I didn't know if those headers had an adapter flange. All of the factory turbos are 3 bolt flanges.

Depending on the turbo, there may be a 3 bolt turbine housing for it. Replacing the turbine housing is pretty easy. If there a local turbo repair house, they may have parts. People who converted their hot air to intercooled might also have a turbo laying around.
