    best to pulley up if you're currently running the 3.25 as u still have stock manifolds. the front manifold, specifically, is the bottleneck/restriction.

    no i dont have rockers yet...the car had the 3.25 on it when i bought it.I would have had no clue if it wasnt for GPF that wasnt good...how much u want for powerlog?Should i go with a 3.4? I just want my ride to be correct.

    Headers would be a better option, but if you were to go up a pulley size to the 3.4 the powerlog will help, and your front pistons will thank you lol.

    Even with the powerlog and your current mods you still might not even be able to run a 3.4" pulley let alone a 3.25". Definitely up pulley sizes, that 3.25" is WAY WAY to small. If I were you I'd invest in a scanner so you can determine what size pulley to run.

    this is my suggestion, pulley up to a 3.4, then get either of the following items or all of them:
    -scanner to scan knock plus other nifty stuff
    -tuner-HP Tuner, DHP PT, Custom Tuned PCM, DHP PCM, or AFC 2.2
    -Front Power Log

    you can also unplug the boost bypass valve connector thats near it to limit boost to 4psi if u dont have the 3.4" pulley yet. grant it, it'll be slower than a stock gtp by slightly ^_^;

    Theres really no way to tell without scanning...the cars are all different and react different to mods. One could run a 3.4 with x amount of mods and be fine while the other one with the same setup will not be ok...It greatly depends on the tune. In other words it helps a lot. But you have to do it the rightway. Not run a smaller pulley than you should and just give it more fuel.


    But to answer your queston with the mods in your sig I ould go to a 3.8...wich is stock

    congrats. you made a good desision. it may seem slower and probably is a little bit but you're doing yourself asnd car a favor. Do it the right way....I almost went about things the wrong way but a cupple people changed my mind.


    now like he said get a scanner and a tuner...you may come out better getting a tuner since it includes a scanner. I will personnally walk you through everything if you decide to go that route. And theres a lot of other people on here willing to help also.
