Default 94 SE Supercharger Upgrade/Mod

I have a 94 SE (non-supercharger) that I want to do a little recreational experimenting with. Is it possible and what should I watch out for to install a supercharger on a non supercharged motor. The few u-pull-it yards here will charge a measely $50 for a supercharge so I thought I might give it a try. What do you all think?

From what i heard putting a supercharger on a non-supercharged 3800 will severely damage it. Even though they are the same engine key components are different, stronger push rods stuff like that. The transmission is different to handle it too. In other words it wouldn't last long with a supercharger.

from what i've heard from several people is that internals are viretually the same and and that is infact what gm does is just throw that supercharger one there. The only problem I thought I would actually have is computer isssues? Does anybody else have any input on this?

If you search the forum for supercharging a NA or normally aspirated engine, you'll see that it'* not as easy or inexpensive to do so.

This is more going to be a for fun see what I can do. Parts I can come by pretty easy for most anything. I'm just trying to find out if internals are actually different or not?

I finanly found some good info on the tech page https://www.gmforum.com/t279634/ so it looks like something definately doable but give the amount of work I think I will wait till I blow a head gasket (if that ever happens). Thanks a bunch for the help.

Just to let you know thats for a series 2 3800. A 94 is a L27. Not sure if that would be any different.

I know a few of the junk yard guys around here, all my stuff has to be from a 94 or 95, or non of the computer crap will work. When (or if) I blow a head gasket then I will just pull heads and everything from a junk yard car and just refurbish them.
