Don't forget, you also have the option of a centrifugal supercharger (CSC) or turbocharger. It'll be a high-dollar setup, but also has the potential of offering some great horsepower results. ZZP'* CSC kit claims to add 60 hp at the most basic level, and 285 hp in the stage 4 configuration. A Stattama turbo kit is also a good option, and can net you over 100 hp pretty easily. I looked at Intense'* website, but I don't see their remote turbo kits anymore. If they still sell them it would also be a viable option.

Additionally, I will have an upcoming report of a fairly cheap, reliable way to pick up some extra ponies without a power adder. Once I get new fuel injectors and my Intense PCM installed I'll hit the dyno and report my results.

There are definitely some options available in the 3800 community. Bottom line: if you have an idea to get more horsepower, chances are it has already been tried on a 3800. Do your research, because there are trade-offs depending on which option you pick. It all comes down to money. If you want to go big, you've got to throw down the cash. I have come to realize that there'* almost no way around that fact.

Hope this all helps!

Thanks for all the info guys!

for the record, i contacted zoomer, and the kit IS currently available for in-house installs

Actually its not that hard to do.

Pretty much just a top end swap, heads on up if you want to do it correctly will all stock parts. Heads/LIM,*/C/TB/L67 injectors/MAP sensor/Fuel rail. And IIRC you can use the L36 fuel rail if you cut it inhalf. If you have access to a tuner your golden.
You can do the whole thing for about $800 COMPLETE (minus tuning). You can run the 3.8 pulley if your doing other mods at the same time i.e. cam+headers.

ZZP sells the wire harness conversion kit (~$40 IIRC). Once the top end is done you just need the L67 balancer and idler pulley.

ZZP has had so many problems because they are trying to pretty much just bolt the blower on an L36.

I mean really if you wanted to do it I would LOVE to do this project again (done it 1 other time). Ed Morad lives about 45min away from me and has EVERYTHING!


People use to say "just buy a GTP" on clubgp all the time, that is such a LAME excuse! Now so many have done "what couldnt be done" anything is possible and sometimes easier that what you think.
For example everyone said (5/6yrs ago) that you couldnt run a NON-HD tranny in a GTP, well guess what. I was the first to stop that myth!

GTPboy, your car weighs less than a Bonneville. That'* ALOT more stress on the drivetrain. and there'* a bunch of hidden costs in your reply.

Is it possible? Sure. Practical for 99% of the members? No. Could I? Yes. Would I? No.

Yeah there is some hidden cost, but most of that is maitenance stuff (gaskets/bolts/fluids)

And I agree to point it normally isnt feaseable to */C a GT/SSE/SE, but to */C an L36 when you already have a GTP/SSEi/GSx is one of the best kick in pants mods there is.

And as far as the tranny, yes the Bonne is ~600lbs heavier so that would put the "weak non-Hd tranny" in a fairly reliable range at MID to low 13s in a Bonne. As we all know the stock non-HD can handle mid 12s in a GTP (taking out the "what if" factor) there have been MANY that have done it.

I plan on running 11s on a stock HD tranny, I've done it before, but every car is different.

Most Bonnevilles run into big trans problems with the 4T65E-HD when they hit 13'*.

Not sure how true this is. There have been 12 Bonnies into the 13'* and as far as I'm aware the only one with major trans issues is Adam'* car. A few like O'Neil and I have beefed the trans up before something did happen but thats another story.
