Looking to put a supercharged engine in a naturally aspirated car what all will need to b changed the fuel rail lines anything else that's all I can think of
Assuming you're talking about putting a L67 in place of a L36, it's pretty easy. Map wiring, BBV wiring, and the tune should be about it. Certainly if you're swapping it in from a different engine or mixing DBW or not it could get more involved.
Posting the year of your car would help and if you're swapping the HD trans in too or not.

Right on man I'm doing this to a 99 grand prix want to know if it's the same for 00-05 monte what is BBV wiring and dbw will be getting the hd transmission or if I don't get one can I use the regular transmission good looking been reading some of your posts
Basically it's just an extension for the map sensor since it's in a different spot and a wire for the boost bypass valve (bbv) solenoid. Since the L36 doesnt have boost bypass valve, that wire would have to be added from scratch if you want to keep that solenoid functional. Certainly could do a DIY version of the kit or delete the BBV solenoid completely and just manually reroute the map wiring.
Like you mentioned, just tweaking the fuel line locations to line up for the L67 rail, a tune, and you should be good to go.
what is BBV wiring and dbw will be getting the hd transmission or if I don't get one can I use the regular transmission
DBW is drive by wire, basically if you got a L32 out of a 04+ GP. They use an electronic TB and also have return less fuel injection so the swap is a bit tougher with that.
Dont forget if you get a HD trans that you also get the matching passenger side axle.

As far as I know, the SC and non SC are the same size (3/8 feed, 5/16 return), but it's probably worthwhile searching GP specific forums to be sure. Should be able to also search 'top swap' as those people will have the same issue you've got.
AFAIK the only issue is line position. Some options I've seen:
-Cut off the plastic hose and run fuel injection rubber hose from the metal hardline directly to the rail with fuel injection clamps. It's certainly the easiest option, but it's pretty ghetto.
-Bend the stock metal lines to get the ends close to the right position.
-Remove and remake the plastic part of the line. They sell aftermarket kits for doing this.
-Adapt the metal to AN and do a braided hose up to aftermarket line connectors. Probably the nicest looking and safest but also the most expensive.
Picked up a transmission from a 99 gtp 140xxx starting the swap today going to pull the engine and swap over the pan and oil filter neck donor engine is out of a ssei Bonneville oil filter is located on the side of f the block swapping coil packs ordering the map extension and BBV wiring also going to pull off fuel line from a gtp swapping the transmission out to hopefully no issues or setbacks
So basically got the motor and transmission in car is running just dont think supercharger is working for boost didn't order the zzp kit remapped the evap valve and map sensor to reach original wiring location wanted to kno if I can just splice the boost bypass valve connector into a power and ground Motor in and running Only missing the boost bypass
wanted to kno if I can just splice the boost bypass valve connector into a power and ground
The solenoid is meant to be able to be switched on/off by the pcm if you're looking for stock functionality. If you're looking for a way to just force it on permanently, then just delete the electric solenoid altogether. The BBV still works fine with it properly removed, it's just the pcm wont have any control over it anymore which isnt a big deal.
