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/EbayAug07025.jpg) (IMG:http://i116.photobucket.com/albums/o33/StanIROCZ/EbayAug07026.jpg) (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 This post has been edited by StanIROCZ: Sep 8 2007, 08:13 PM |

QUOTE (Phoenix57 @ Aug 22 2007, 11:03 PM)  do u know what power level an individual one is rated at? im lookin for one for another project(turbo efi 225ci slant 6), but not sure if a GN one is big enough or not 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. |

Ok, found my notes that I collected from various sources online (Turbobuick.com, turbo mustangs, thirdgen.org etc)
TBO348 Similar to TO4B S-2. (The closest map I could find online is the TO4B S-3) 73% efficient at P2/P1=1.82 and 20.8 lbs/min Surge at 13.8 lbs/min peak flow 37.3 @ P2/P1=2.5, 60% efficient |
