Can I use a 2g manifold with my 13g?

[92GSXman]

I currently have a 92 GSX with only 90k miles on it. The turbo seems to be in good shape as it still boosts nicely and the car doesn't smoke. My 1g manifold is cracked in 2 places and I have a 2g manifold waiting to go on but I don't think the flanges are the same. Can I use this manifold without swapping turbos? Oh yeah, my car is an automatic....

yeap ya can.

Yes it will bolt up, but you may loose some performance because the outlet on the 2g manifold is way bigger than the 13g inlet.

I've thought about it alot more and I think I'll still wait until I get a different turbo and do it right the first time. Thanks for the help anyway guys!

that wont cause noticable performance loss.

OK guys, this leads me to another question. Why does buschur include a manifold with his 1g automatic 16g kit if the stock manifold will work? I swear I've heard that the 13g has a slightly different flange on it than the 14b/16g does. I mean if this 2g manifold will work with my current set up and not cause any performance loss I'd still use it.
