Has anyone done this swap? I have the turbo i was wondering if the rb25 dump pipe will work or if i need to swap it for the rb20. Also i was wondering where to get the t3 exhaust gasket from? from the turbo to the manifold? Do you guys think it will be safe to run the rb25 turbo with no s-afc? I have a greddy profec b so i can turn the boost down until i get an s-afc. Any help would be appreciated.

Yeah, this has been covered a number of times, here's a decent writeup on the swap: http://www.project32.net/tutorials.php

I was wondering where i get the turbo elbow gasket, and the turbo to manifold gasket. Like maybe the part numbers?

Bro its a regular T3 Gasket.If you bought the RB gasket kit, its int there.

The turbo elbo?Do you mean the Turbo outlet/dump on the back of the exhaust housing?

Or the one on the compressor housing?Compressor outlet. Rb20 and RB25 ones are different, found out the hard way lol.
