I did a turbo on my 3800 that is in my Fiero but it is not a kit. There are a few things you should know first. I have not been to those "vendors" to see what they tell you has to be done but I know this:
The L36 has weak rods and pistons that are not boost friendly. When I did the turbo in my Fiero, I started out with a stock L67 shortblock and added a pair of ported L36 heads and a 96-up Camaro all-aluminum intake. Then I modified the stock exhaust crossover to feed a stock 87 GN turbo. I capped off the rear manifold and built the rest of the induction and exhaust system myself. Obviously, this is where a "kit" would help someone that does not have the tools or fabrication skills neccessary for this type of work.
In short, the stock 87 GN turbo was good enough to put my 3000lb (minus driver) Fiero into the low 12'* with only 15 lbs of boost and the stock L67 cam. Basically, I have been following the turbo buick (GN) community for some time and I am using some of the same formulas they have used to go fast and it has gotten me there on a very tight budget. Obviously a Bonneville is heavier but you guys have a lot more room for an intercooler and more options when it comes to exhaust.
Drop me a line if you have any questions or need any advice on what you need to do for turbocharging.
