    So am currently in the process of getting everything for a 3800 top swap on my 2004 Grand Prix GT, I have the pulleys and harmonic balancer I need, I also have a Gen3 M90 blower. My question is will it fit on my 04 after I get the lower for it or will I have to get a Gen5 blower? My motor is the...
  2. Intake
    So I finally found a cold air intake that fits my 03’ Bonneville ssei and I was planning on asking for it for Christmas but I’d like to hear from anyone who knows something about this intake or anyone who has this intake. Tell me about it, any advice, concerns, or recommendations. If you do have...

    So I've finally gotten myself a GTP, really fun car so far but it does have some issues with it. First off the rockers are basically gone, my plan is to weld reinforcement metal in but I'm not sure how to go about that quite yet any suggestions are welcome. Secondly, the transmission is a little...

    I’ve been searching the forums and I haven’t found a discussion regarding my question yet. Perhaps I haven’t looked hard enough, but my searches anywhere else online aren’t taking me anywhere. So, what’s the best year for the GTP? Which is considered the most reliable? Are all model years...

    Hi all! I am looking to do a supercharger pulley swap and was wondering if anyone would be willing to sell/rent me their used supercharger pulley puller tool? I would be willing to pay you whatever you think is fair, I'm sure someone has one laying in their garage not being used so I figured...
  7. Superchargers
    Hi, I just bought a '90 Park Ave in very good condition, and I'm looking to add a supercharger to it. From perusing the Internet, it looks like the Eaton M90 supercharger is the most common one used, and I would like to fit it on my engine. I have the 3800 LN3, and I've read that it can be...

    I'm swapping my motor in my 99 regal gs SC. The one we got from Robbins in illinois we believe was from a gtp. We switched everything we needed to over and are about to place it back in my car and we noticed a small drip from the bolt on the supercharger pulley. I've looked up a few things that...

    Hello everyone. I just changed my Supercharger coupler due to a rattle/rock noise. At first the noise went away, but now only a week later the noise is back. I also have what I think is a leak but have not been able to pinpoint it yet. My question is has anyone changed a coupler and if so...

    Hey guys, I wanted to see if anyone was interested in my old L67 SC? I replaced it a few weeks back and I was thinking that some of the parts may be useful to some others be fore I scrap the rest. It has 183K on it, with a light knock when I yanked it out. I didn't feel like trying to fix...

    1998 Grand Prix GTP... I have a rattle at idle and seems to go away with any rpm increase.. putting the trans in neutral seems to help some with the rattle. Placing my hand on the nose of the supercharger while idling it seems I can feel the rattle in the casing. Nose Cone Bearing? Timing Chain...

  16. FWD 3800 Engine Swaps
    I have just completed the engine swap, putting a 3800SC from what I believe is a 99 Grand Prix GTP into my 97 Bonneville SSE which was normally aspirated. Pretty straight swap from the bolt up perspective. Swapping the flywheel was the only change I made to get it bolted up. The electronics...
