    the GNX that chevys10 mentioned are not twin turbos.

    They had the same engine that the standard Grand Nationals had, but with a ceramic turbo (to quicken spool up) as well as a reworked intercooler and transmission.

    and yes, they were the fastest things around back in the late 80s and early 90s.

    Christ, that thing could power a battleship. Any guess as to what it would run *if* it hooked up okay?
    IIRC his best with that engine was 9.xx
    he has since swapped engines and now runs 8.xx And If I do remember it is street legal.....LOL!!! I would HATE to accidently run into that thing on the street.
    Stock or something close to it.....

    Yeah I think its the same engine as the GN and T-Type. Single turbo, different intercooler and maybe bigger injectors and stuff. I'm no GN expert either.

    Anyone ever read the story about the guy in the baby blue T-type smoking the single turbo RX-7. It was on the camaro board like a year ago. I shoulda saved it. Pretty much the guy in the 7 was like "is that a grand national?" the guy in the T-type: "Nope " After he put about 4 buslengths on the guy they pulled over and he told him what was up. Its up there in my fav. kill stories. Bested, def. though, by the 97 'lude with i/h/e who thought he would beat a supercharged LT1 because "I have vtec, dude"

    Thanks for clearing that up. That is what I thought too. If I had the choice though I'd get a 20th Anniversary Trans Am (1989) with that same Buick Turbo V6 in it. Personally, I just think the 3rd gen F-bodies looked better than the Monte/Regal/Olds Cutlas bodies of the time.

    This talk is getting me pumped up for the Car Craft Nats in two weeks here in St. Paul. I'll be taking lots of pics and post some here for you guys. Should be a few GN's and plenty of "old school" muscle.

    Grand Nationals are 4.3L single-turbo monsters. All variations are single turbo with various levels of badassness.

    Wrong! All GN's, Turbo Regals and 1989 20th Turbo TA's are 3.8L Single turbo. The only 4.3L Turbo vehicles that I know of are the GMC Typhoon and Cyclone.

    The GN in this discusion is no where hear stock and as mentioned may have a SB V8 instead of the V6.

    While the car makes some serious power, the owner is a ****. And why take a real GN and throw in a v8? The little 6 is what makes the car special. Put a V8 in a regular regal. My dad's smog legal 4.5L (V6) GN is not much slower and he actually drives it to work once in a while. I don't mean to be cynical, but I don't know why some peope think they're better than others because they have a faster car.

    Ok, I just seen a thread about this on another car side and this is what it is siad to have:

    "Chris Chow's 87 WE-4. The motor in the car belonged to Bob Rieger originally, who had the motor in a tube chassis car that made 1800 hp with the boost turned up. The motor, a 390ci SBC with twin T-76 q-trim turbos, is in a de-tuned state in order to avoid twisting the stock chassis of the buick. The car has went 8.50 @ 162, coming out soft since the only really suspension the car has is a wolf-bar, along with drag shocks and springs. Also it is a small tire car(28 inch)."

    Here is a track run video....
