Is it the same Turbo on a 3.4L GTP as our 3.1L TGP?

Is it a T25 turbo on the 3.4L GTPs as our 89-90 TGP's, I take it if it is it would be a straight swap?

3.4 GTPs were never turboed from the factory.

1989 and 1990 ONLY were the years for turbocharged Grand Prixs...the TGP
1991-1996 Grand Prixs get the 3.4 Twin Dual Cam engine, not the turbocharged 3.1, and certainly not a turbocharged 3.4...such stock engine never existed.
1997-present, GTP's get a supercharged 3.8 liter, a.k.a. 3800.

So, to sum it up, what Nick said is correct. There was never a turbocharged GTP, 3.4 DOHC, atleast never stock. The one's that are turbocharged are custom built by people who have incredible patience and enjoy life's greatest challenges lol.
