Default 2001 bonneville 2001 grand prix engine

I was just wondering if the 3.8 3800 in the 2001 Bonneville and the 2001 Grand prix were the same, including exhaust manifold, intake manifold and throttle body? Was looking to put a cold air intake and exhaust system on my bonneville.

Rear exhaust menifold is different, every thing else is the same, a cold air intake and exhaust from a GP wont fit however, try going to www.intense-racing.com and pick up a fenderwell intake set up.

i do not remember specifically how it differs, i think maybe the )2 sensor location or something, someone else could chime in here with more detailed info.

if my memory serves me correctly its like TJ says, the rear manifold outlet is shifted a little, so the h body downpipe wont bolt up, 95naSTA had this problem when he bought a rear ported grand prix manifold, he had a new downpipe made up though.

yea i would like to hear some more about this because i am considering buying a set of hulkspeeds pems and a jimmycdp. But i want to be 100% sure they are going to mate up with my bonneville. I know my motor is out of a 2001 grand prix and i have my 1995 manifolds on it so they match up that way. But i want to be sure that the grand prix rear will not have any o2 problems or clearence issues? ect?
