Got bored and started making build video...

@  dezldave961 : (04 May 2020 - 04:05 AM)

I need to hunt down the little black trim bar that's at the top edge of the GS rocker panel cover, for driver's side between rear door and wheel well.

I've been on there too. I hope this forum is kept open, there's too much info to allow it to be lost!

@  dezldave961 : (24 April 2020 - 10:25 PM)

I've been monitoring GrandPrixForums and 3800Pro (don't have FB)... also hopped on TurboBuick, but 99% GN chatter from boomers

Everyone at home, plenty of free time.

So far so good. Still working, fortunately.

@  monte0 : (17 February 2020 - 05:04 AM)

@  ejguillot : (14 January 2020 - 10:36 PM)

Hope the new year is treating everyone well..

Hi all. Decade is coming to a close... I'm feeling a little old!

Hi there. Some of us are working to keep these cars alive and running. Glad you had a good 15 year run.

@  opera_bob : (30 November 2019 - 08:39 AM)

Every time I see an Old Buick I have major respect for it. I know what kind of torque these cars make.

@  opera_bob : (30 November 2019 - 08:38 AM)

I sold my 2002 GS back in 2017. She was falling apart all over the place. So I sold her and bought a 2017 Focus RS in 2017.

Slowly working on a project GS... HP estimate for the parts going in the buils

01 October 2019 - 02:36 AM

Hi everyone,


It's been a long time since I posted, and longer than that since I started the project build on a 98 GS.  Today's topic: With the parts I'm putting on the engine build, what would you estimate WHP to be?


Pulley size: negotiable.

42lb injectors.  May upgrade to 60's and uprated fuel pump and run E85

180 degree thermostat

Intense Motorsport Stage 1X cam, stock rockers/pushrods/lifters

Ported heads with oversize valves (Bought these from Robert Moschella, who was once active here many years ago.)

Short stack intercooler (Bought that used years ago as well, I know that an full stack would be better)

Port matched LIM

Gen 3 blower, will do light porting to outlet, and port/polish intake

Northstar TB, LS series MAF (bought so long ago, will have to look up the part number), drawing from fenderwell CAI.

XSPower 3800 headers, dumping into Hogan Performance 2.5" single mandrel bent exhaust. (Maybe I should have gotten the 3" instead.)

Dynomax VT muffler.


Computer tune: Will have to be redone to match this setup.  For the purpose of this estimate, assume a proper tune. Redline to be set at 6200 RPM, until I can get a crank dampener that can handle higher.


Put your guesses below! From what I've read in this forum, should be at least 300WHP.
