    Default need help 03 olds

    Recently I bought a 03 oldsmobile alero 3400 v6, I want to make a sleeper out of it, but I cant find ANYTHING to add to the performance of this engine, only the 4cyl..I would really love a computer tuning program I can run off my labtop but EFIlive doesnt support the v6, anybody know of another program? or any parts?
    Thanks in advance,
    Justin

    A lot of the performance upgrades from the 3.1L and the 3.8L will work on the 3.4L. Me personally i would try to find a suitable intake the drop a 3.8L supercharger on. and then program from there.
    And i would try black bear performance for a custom tune, since that may be your best option. I believe headers from the 3.1L will change over, as well as the cold air intake.

    ok, thank you I'm new to all these engines and was searching for parts for a 3.4L, a 3.8L intake will fit on with no mods? and as for the supercharger, I've heard a eaton m90 or m62 will fit, is this correct? honestly I would rather have a tuning program so I can change the tune anytime I want and have multiple tunes so I'm not running the engine to hard when I dont need to.

    that was my question as well about the 3.8L to 3.4L intake. Im not 100% if they will since i never got that far with my 3.1L monte carlo. I got the supercharger and was working on the headers when the wife found a deer and it ended the project. I know that the 3.4L is really a 3.1L with a bit more bore. So anything that you can find for a 3.1L should be more than compatable with the 3.4L and some things from the 3.8L will work as well.
    As to what superchargers, me i had a late model (1999 GTP) supercharger, and i have no idea what style other than factory 3.8L because i really am not into the numbers like that and cant remeber some of it either.
    OH And i know this get SOLID dog bones for it (upper motor mounts) that will help in the throttle response HUGE!, Another thing to look at if you keep it NA (which the 3.4L is not slouch NA so if nothing else a custom tune, and headers with a good flowing exhaust) is to port match the upper and lower intake. Also take a look at over and under drive pullies.

    sorry about the car, and the 99 GTP S/C was a eaton m62, I was lookin into one of these kits but was told not to waste my time the m90 is a much better deal for the price. I've also looked into some pulleys but I dont want to sacrifice anything like alternator or A/C efficency as its going to be my daily driver, as for the port matching, Could I measure it out, mark it, and use a rotary dremel? or do I need a certian tool for it

    Rotory dremel works great. Just be sure to not take out to much meat.. Remeber to measure twice.. And i get your point on efficency as a daily driver. And i dont really know what the m90 is. As i said not my cup of tea.. But i got the M62 for $100 and i removed it. The guy was parting out the car after a really bad rear end collision. I was just going to take out the whole powertrain and instal it into the car, but decided i wanted to see how far i could push the 3.1L before she let loose.
    My old boss had a series 1 3.1L and it hauled the mail. and he did a port match, a good set of headers, and port and polish, and a custom made 2 1/2 in dual exhaust..
