    Default 3.8 forced induction

    So, I have a 17ft tunnel hull mold (I own the old Hawaiian 17' mold...only a few jets built). The passenger compartment is not huge so I am kicking around the idea of going with a 3800 out of a camaro so it will bolt to a bravo setup. I think it would be a great package and give a lot of options as far as power output. Could be NA, turbo or blown...all with stock GM parts.

    This brings me to a couple questions: Has anyone ever marinized a buick 3800, privately or commercially? I know exhaust and will be an obstacle. I am open ears on accessories and any other possible problems or suggestions.

    Supercharged 3800 from a buick park avenue wld be a awesome start! Very hardy motors that are blown from the factory.upgrade the injectors and lil smaller top pulley along with supporting software in the pcm wld make for a nice motor in jet. same motor as the camaro as far as bolt pattern at bellhousing

    Dare to be different, if it turns out great you can claim you planned it that way.

    I did not know they had a chevy bolt pattern. That definitely simplifies things as I was planning to swap over the blower.

    Also, some may wonder why I am not interested in a 4.3 platform, packaging is a big concern because of the tight passenger compartment. And to put a low profile blower on a 4.3 would not be as easy. Not that I would mind a 71 series blower, its just that I would like a small usable sun (bitch) pad over the motor.

    I did find this:

    I know the 4.3 does have the common chevy bellhousing but i dont know of a 3.8 that did, even the camaro 3.8 is different bellhousing than the v8 equiped camaro.. 4.3 is a nice platform but expensive and arent fond of rpms in stock form.if you cld fit a alum blocked ls 5.3 with a good stock camaro fuel injection setup thatd be a lite high hp package without the need of boost.i run a 16ft mantra tunnel with a twin turbo 5.3 but i never needed a motor cover.

    Damn, that sucks. I assumed it was a block change. That makes things a little more difficult although an adapter plate is not a big deal. I would still like at least a 4 person passenger compartment so the longer 5.3 is not an option.

    Tom Earhart has put a turbo on a stock 3.8 buick V6 in a 19' Eliminator Daytona v drive and ran 116
    with it.



    He always ran oversize big blocks before and now is at the opposite end of the spectrum.

    He said he runs 20# boost on E85 fuel and the motor made 825 hp on the dyno.
    He also said he can get a brand new crate motor for $ 1,200.00 so its a cheap assembly.

    He sold the Daytona and has since mounted the V6 in a hydro that he bought.

    I thought of this idea. I'd like to hear how it worked in the hydro.
