I was just thinking... what are some big time HP upgrades for the Bonneville 3.8 V6. I'm talking 100-200hp boosts. I'm pretty new to tuning cars (getting real interested once I got into Grand Turismo) So is such an upgrade even possible for it? Superchargers/turbochargers what?

for a Supercharged.....better off buying an SSEi......

Otherwise go to www.seriesoneperformance.com there'* LOTS of performance parts there for ya....Cams, rockers, springs, NOS.....All sort of fun goodies....

I don't think there'* any good upgrades that could yeiled that much of a gain on the parts available.

Biggest increase in a series 1 could be heads/cam. They're not exactly what most enthusiasts would call a performance setup...

But no one makes heads in this country.

Sorry, forgot to mention I'm talking about the Series II.

Holden make'* them in AU don't they? Or something like that?

as for upgrades it depends on what kind of money your talking about spending. if your strapped for cash i would suggest starting simple and going from there. Try the CAI and remove your MAF screen then move onto the ignition system by replacing wires and plugs (research what application suites your car best). Then replace your muffler and replace your catalic converter with a high performance muffler and catalic converter( possibly a cat back system). Just this alone done right and given plenty of thought and research will give you some noticable increase but not as much as your asking about here. Just remember that everyone has to start somewhere'*. Surfing the different topics and asking questions is probably the best way to research any upgrade. I consider myself very mechanically inclined, but when it comes to working on my bonny i always research and ask question, you'd be amazed the helpful information that flows through this site.

The biggest drawback with your car would be it'* PCM.
Check out INTENSE'* site, some of the stuff there will give you an idea.

INTENSE doesn't offer a PCM for 95 or 96 Series 2 Bonnevilles, and the PCM in the 95 is the hybrid obd 1/2.

Heads, Cam, Headers, keep all that mild unless you want to spend an arm and a leg on a prototype pcm. Do the intake, exhaust and 180 thermostat along with all that, and consider a trans cooler.

95naSTA has a PCM or a chip from GM tuners, ioxmo, check out all stuf that 95naSTA has done to his car, that will give you an idea of where to go

I wasn't really asking for help on upgrades, but thanks! I was talking what are some big upgrades one can do if they have deep pockets.
