Might not me much interest on this forum, but hell, I'll give it a shot anyways.

At one time I wanted to slap a couple turbos on my TPI and get an easy 500 HP, then I became a FRRAX freak and the car got other priorities.

I have 2 86-87 GN turbocharges for sale. The first one is shown in the following pics:

(IMG:http://i116.photobucket.com/albums/o33/StanIROCZ/EbayAug07027.jpg)

Neither turbo has damage to the fins or rubbing of the fins onto the cold or hot housing. Neither one had signs of burning oil etc.

I checked them both for axial and radial end play, and they both are within the acceptable limits given by Turbo's Direct.

I also have a '7749 ECM (SyTY) to go along with these.

$250 each for the turbos - Price reduced to $200 - One turbo sold
$100 for the ECM

I'm pretty sure that GN guys stretch them out to about 400 HP with a lot of boost. I wouldn't do that though because I'm pretty sure that's off the map and not very efficient. I would say that 250-350 is a good range depending on how much boost you are running.

The buick motor that these came off of is a 3.8L.

If you want to look at some maps I've heard that the TO4B S-3 is the closest match.
