Question want more HP in my '97 Buick 3.8 L V6

Help, please ! I have a 1997 Buick Park Avenue. I know that sleds are not very popular right now, but I love this car! I have a couple of fractured vertebrae in my back and this car just eases roads little bumps.

My car has 200 HP from the factory. I believe it is basically the same V 6 engine the 87 Grand National Buick had in it, and that car was a stormer!

I want to boost my HP to about 325. I want it to remain a no hassle car, as I drive it about 400 miles a week. I also am not a rich man, so I would like to keep it as reasonable as possible.

I will GREATLY appreciate any help, if someone with knowledge can spare the time.

I will need to take it to a garage to get it done, as I mentioned I have a bad back. I can do a little under the hood, but not much.

Thank you for taking the time to read this. If you can help an old hot rodder out, my the sun shine on your journies and the birds pass your new wax job by.

Thank you!

you could go the same route as the grand national and put a turbo charger on it, probably would also want to consider a chip and larger injectors, i dont know if it will be worth another 125 ponies though, and im sure there are many other considerations to take into account when adding boost on a FI motor that i am not aware of.

The buick grand national did use the same engine with a turbo on it how ever the present day pontiac bonyville and soon to be impala ss use the same engine with a super charger. I"m not sure if any after market super charger kits are avalable for it but one could probably be pieced together from one of those cars and would be alot easier than trying to adapt a turbo from a grand national to work on it. with out resorting to forced induction I don't think getting 325 horse power would be possible especially while keeping any degree of streetability anyway.

by just putting a stock supercharger will increase you HP quite a bit. we own a 92 park ave ultra & I can tell you that I "KNOW" it'll do every bit of 140mph & then some , yep I have had it going that fast, basicly the stock 3800 are rockets anyway but add just a superchager and the power is multiplied. the only problem you may have is, the wiring may be different from the non-superchager motor to the supercharged ones and you would have to change the computor also. the superchagers I have found have cost about $1200-1500 rebuilt. sooooo good luck w/that full size pocket rocket...........joe

A good source on info...

If you're not already a member here, it's a good place to start. There's an entire section for you 3800 guys.


Less specific to later 3800's but valuable nonetheless are:
