I think not.

Stock case off Riviera:

Photobucket

Case off 97 GTP

Photobucket

Anyone know of any possible way to make that work? The one from the 97 GTP is the one I put all the time into porting. No big deal if I need to port the one off the riv, but If I can save time I would like to do that.

Is that painted blower the original off the 1997 GP? I thought those castings started in '98. That fitting isn't a really big deal. You can just reroute the lines that connected there to the fitting on the front (passenger side) of the lower intake manifold using a tee. The BBV circuit and FPR will work the same off that port.

Yeah, the black one is the one off the 97 GTP. The guy I got the motor from was a fucking idiot so it could possibly be a 98. Thanks for the heads up, I was thinking that would work since its all vaccum created by the incoming air. (i guess)

Right, just make sure you use the LIM port only. The other ports on the blower are vac only. The bottom side of the boost bypass actuator and the fuel regulator need vac/boost.

the top blower is specific only to 1996 riviera's and Bonneville. The port is to run the transmission off of.
I have a 96 riviera blower already ported with a 3.4 pulley on it if you are interested. ready to ship...

edit: you can use the gtp blower you will just need to be creative with the vac routing. the trans can be a little sensitive with how much/little vac it see's too.

Cool, I'm going to try it by going to the front of the LIM. If I have problems with the tranny shifting then we know what the problem is.
