- 2005 Passat daily, a bunch of others in the graveyard out back...
so i picked up a used VNT15 to replace the one on my car that has sticky, notchy vane movement.
While cleaning it up i thought to myself that the cold side looks exactly like the GT15 from an AHU. This led me to think "can i strap a 1752 wheel onto it?"
I made a gt15/17 hybrid on the the passat for a whopping $12 in junkyard bits... nothing special but it spooled fine and smoked less on WOT than the stock turbo so i called it an improvement - even if it really wasnt, let me lie to myself in peace...
I assume the larger effective A/R of the VNT's exhaust side will be better at handling the bigger cold side than the tiny GT15 turbine housing did... The GT15/17 seemed to just choke itself out at higher rpm because of this.
So the question is, can the saab's 1752 backplate, comp housing and wheel be bolted on to a VNT1749V? If so, will it provide any improvement over the stock unit?
