Yeah although a odd setup with the 3 boly inlet flange there is a ton of support for the Buick GN style turbos. the TA49 is a stock looking turbo that alot of GN guys are pushing well into the low 11's. They preform just like stock ones till you get over 15psi so a nice one to use and work up with.
I would still like to find one of the large 292 manifolds with the 2.5in outlet and rework my tubing to hopefully get better flow in that also. Although ive located another stock manifold that im going to play with porting out and blocking off the heat from the intake...
