    I bought a 1999 Firebird from a coworker for $400 dollars. It had oil and coolant mixing, so figured it may be the intake gaskets (bad on these motors). I swapped them out but the motor ended up seizing after a short while.

    I bought some wood to build jackstand extensions from home depot. Loaded them in my utility vehicle :doh:

    Lifted the car up and dropped the motor out of the bottom.

    The new motor came out of a 2008 Buick Lacrosse

    I had to strip it down to pretty much a long block, lots of unusable parts. I swapped over the old motors lower intake and installed all new gaskets.

    I figured while I'm at it, I'll go ahead and do an under k member turbo kit too.

    It runs fairly strong at the current 4-5 psi of boost I have it at. I want to add water injection, FMIC, BOV, bigger injectors and fuel pump.

    Not sure what to use to tune. HP Tuners stuff looks awesome but pricey. I also need to sort out the PCV system and fix some leaky valve covers.

    E85 or 100% meth injection would go a long way!

    Nice to see some other V6's out there. Cheap LC2 3.8 build went 10.06 last year. :2thumbs:

    Glad to see you back at it! Your 3.8 mustang build is what inspired me to build mine. I am going to be running a hy35 as you did on monoxides setup. :2thumbs:

    OH YEAH!!!

    I'm signed up for this one, I've always wanted to see some more v-6's in action.

    Anyone have any idea how much power can the stock 3800 stand?

    :corn:
