1991 Buick Regal Limited 3.8litre Supercharge

[AlienEvolution]

Assuming i could get ahold of a supercharger for my buick, how difficult would the installation be for me? I do have more than average knowledge about cars and how engines work, and work very well with my hands.
What things would supercharging my buick entail? would i have to have it tuned to work properly, or make modifications to the CPU (also not a problem, i have a lot of experience working with home computers and electronics)?
Furthermore, would weather such as snow and heavy rain effect the engine in any way, I will most likely have to cut a hole in my hood (which i have no problem with) to allow the supercharger to fit.

Thanks!

Just find a supercharged engine from another GM car and replace the entire engine and ecm. That has to be easier than trying to add a SC to a 91 Buick.

I have a 99 Regal GS (a supercharged version) and I believe some internals are different in the 3800 SC version than the standard 3800 version. Like I am supposed to use premium gas (92 octane) vs regular gas (87 octane) in the standard 3800.

replacing the engine is not an option.

If you want to use your existing motor, your only option would be to look for a supercharger from an early supercharged 3800 and it should bolt right on. Cars that have this engine include the 1992-95 Buick Park Ave. Ultra, Pontiac Bonneville SSEI, and Oldsmobile 98 Touring Sedan. On all of the above listed cars the 1992-93 engines put out 205HP. The 1994-95 engine put out 225HP. The only internal difference between the N/A and the supercharged engines are the connecting rods. The fuel injectors are also different 22 Ibs./Hr for N/A, 28Ibs./Hr. for supercharged. The supercharger shouldn't take up much more space than your current intake. You will probably need to do a PCM swap as well. There isn't much tuning that you can control. Your 4T60 tranny may need to be beefed up as well to accomodate the extra power - it can't take much abuse as it is. I don't know much more than that. Good Luck!

i found out the hard way a superchasger will not just bolt onto a 3800 you have to get a supercharged 3800 or rebuild yours to match the power gain... i got 1 out of a totaled gtp took it all apart went to 3800preformance.com and got all new internals built it up..got a stage 6 ecm and installed it into my 93 regal custom coupe... leme tell yea dont let all the work fool yea its fast as heck! well worth it! with my new tranny i havent lost yet! i have an 87 grand national and id hate to say it but my 93 kicked its but! and my gn has tuns of mods!
