    Talking need power

    i have a 99 grand prix se with the 3.1L in it. i was wondering if there is anything out there to get more power out of it. i found headers, exhaust, and injectors for it but what else is there. i already have a cold air intake.

    The most practical thing is to trade it for something with more power. You're kicking a dead horse with a 3.1

    You'd notice a larger difference swapping to a GP with a 3.8 than if you add the injectors, headers, and exhaust, and there's an unlimited aftermarket for 3.8 accessories.

    surprisingly, it has alot of noticeable power. i was spinnin the tires on it through 3rd gear and still averaging around 21 in the city. ran a 16.3 in the 1/4. i just want a little more out of it and it was a free car so it's not like i'd be losing money with it

    Find a wrecked 3.1 turbo and use the turbo kit!

    You're gonna need some internal mods, don't just slap on a turbo. You'll be looking for an engine next.

    3.1's are cheap as chips, go to U-pull and get a new one for a c-note if it blows up...

    I say put NOS on the ****er! A 100 hp shot should do the trick. Yee haw!

    Spinning tires in 3rd with a 3100 automatic, sure, maybe if you were driving on ICE


    Trying to find the turbo parts from an original ASC/McLaren car would probably cost more than an easy L67 swap...

    Unless you have a fully equipped garage, with tools, hoists, and the proper braces, the fun goes out of pulling and replacing these engines after a couple of hours. And with a piston hanging out of the block, you don't get core credit.

    If you do have the proper setup to do so, the fun goes out of pulling and replacing these engines with the first one. And with 2 out of 3 of those "c note" engines being crap, you'll get a lot of experience.

    Depends on if you want to turn wrenches or drive.

    Re: need power

    well i'm a mechanic so i would be tearing motor apart and beefin it up. i would just love going to the drag strip and running fast times and people ask what motor is in it and just say "just a 3100"

    I've done plenty of driveway / field engine swaps with a set of Craftsman wrenches and a cheap hoist... then again maybe a W-body is a pain to work on but they don't seem too bad, especially a 3100... probably easier to change the engine than to change the damn spark plugs (now that is a sucky job! At least on a 3800)

    And of course to build up the bottom end you need to pull the motor / buy another one anyway

    We can have fast, reliable and cheap but only two of three, so might as well take the fun while you are young enough to care

    Re: need power

    well i like to make the underdog motors fast. i did the same thing with my 91 buick century with the 3300. it was slow when i got it, maybe topping out a 95, but when i was finished i ws running low 15's in 1/4 and topped it out at 143mph.
    i know it may seem like a waste of time but i like doing that kind of stuff just to show people the potential of these motors.
