Default Forced Induction On A 1999 Bonneville?

[/i][/b] I was wondering if it was possible to somehow upgrade or do somthing to my 1999 bonneville'* engine to supercharge it or make some sort of forced indcution change to it. I've heard a lot of talk of some people around my town just putting turbochargers and trying to upgrade their exhaust and fuel injections on their normal V8 engines. would this be possible for me to do? please help! by the way, i'm a girl who doesn't know much about cars, but i really want to boost my bonneville!

Welcome, South Dakota.

Simply adding something to the top end doesn't really get you where it would an Acura or Honda, or any larger car. Our cars already put out quite a bit of power non-supercharged.

In a nutshell, Turbo Kits are very expensive, and transmissions don't last long (need to be beefed up as well).

Plan on at least $5k for a Turbo.

A couple top swaps have been done to get the L67 SC on an L36, but I have mixed feelings personally about the longevity of it. If this is your only car, don't go that route.

Like Willwren was saying, you can supercharge your current engine, but...

-long term longevity is at risk. Willwren has stated many times that supercharged 3800s have much improved internals for the obvious extra strain.

-Unless you are willing to pay for it, you are going to blow the tranny much sooner than you would with a stock engine.

He did it. And did it. The transmission in your car isn't the same as the transmission the supercharged Bonnevilles get. Not nearly as strong.

I usually tell people that are determined to do this to have at least an extra $2k budgeted and sitting in the bank first. So when the trans goes, you're ready.

I'm already supercharged on both cars. Adding power to my FUN one cost me my trans in the long run. This is true for every car here.

The little ricers and RWD V8'* can be different. Ricers don't have much power to begin with, and are very light cars. RWD V8'* generally have stronger transmissions. We have heavy cars. This weight puts stress on the transmission.

Some motor life will be lost, but I don't think forced induction at least in the form of adding a supercharger is THAT detrimental to the engine. I've run for almost 20k miles with no increase in oil consumption and positive oil reports from Blackstone Labs.

That'* with an LN3 though. I can't say for an L36 cuz I don't have one and haven't worked with them.
