    A budget would help. You're going to want a transmission though. To get to 12's your be breaking them like no one's business.

    Triple Edge Performance - Home Page for the Trans.

    A turbo kit would get you there for sure.

    ZZPerformance - Go Fast... Not Broke | 3800 | Ecotec | Sonic/Cruze

    Alot of LS parts will work on your car. It's just a little bit harder to make them work being a transverse motor and all.

    I don't know alot about the LS4's but I think someone even makes headers for them now.

    i plan on keeping the trans. doing a tranny flush, new filter, getting a external trans cooler. and getting a ls4 heat reduction . the trans will be fine. and maybe build the externals. and the budget im open to anything. price is not a problem.

    I thought it was only good if you dropped the tranny pan out and cleaned all the shavings. But i read from gm they have new dextron iv and u wont ever need to do a flush or drop the pan again or somthin like that

    LOL and they also make cars that don't rust anymore

    I provide mail order LS4 tuning on my website. Basic boltons plus a tune make a nice difference for around $1000.

    If you really want 350whp, turbo is the way to go, and with a proper trans upgrade expect to budget around $6000-7000 in total.

    If price is not a problem, get rid of it and trade up for a G8 GXP or something else rear wheel drive with more power.......problem solved.
