    well... i havent really looked into what size turbo i want to use and i would be taking a shot in the dark if i threw one out there... but for that head should i be looking for a smaller or larger turbo?

    smaller or larger is very vague. What particular turbos are you looking at?

    well can any one give me a good middle ground suggestion for a turbo... say around 400 dollors spent? from the cars ive rode in... i like the bigger turbo effect more.

    :) You've been nicer than usual to this guy.

    To the OP
    :search:
    There is a reference section here that you should read through, and many other good FAQ's and reference articles about turbo sizing and the capabilities of different turbos, we're not gonna spoon feed you answers to very broad sweeping questions. You need to do a LOT more research.

    we'll id like to exceed the 300whp factor... so do you maybe suggest the LS stock head or another head? the reason id like to stick with the stock head is... well i already have it! or will already have it

    I would think a cam upgrade would come before head porting. I don't think too many people who port their head are running stock cams :shrug:

    You need to elaborate on what you mean by "be fine"

    example:
    "would a stock head with just a port an polish be capable of XX hp with XX turbo"
    "would a stock head with just a port an polish require an upgraded camshaft to take advantage of said porting"
    "would a stock head with just a port an polish give any significant power gains with all else stock"

    These are the type of questions we can answer, or help you find answers to. We have no idea what you mean by "be fine"

    ok hows this... with the set up im looking at ( LS block, forged internals, stock crank... with a LS head with just a port an polish running a t3/t04 turbo on roughly 12 psi) be suitable for 300WHP using the stock head with just a PnP:huh:

    I really dont think just a PnP on the stock head will handle that truly I'd run 8psi at most if any of the parts are gonna be stock/We just blew the head out a b20 from one slite misscalculation. My advice is take your time in figureing out what parts your gonna use and be carefull while tunning!
