    LS1 turbo ???

    Just looking for any suggestions/opinions if my setup sounds good cause im a little more used to workin on modular v-8's

    Im fabing up a car for a buddy itís a 2002 trans-am ws6 now it has a moser 33sp 3.91gr 12bolt, built t-56, stock long block, ms-3 cam, 6.0lr intake, long tubes no cats slp loudmouth, Dyno 426hp 414tork, full spohn suspension

    going to .05over diamond boost pistons 9.4:1 lunati H-beams, hogged out 6.0lr heads with 1.60 2.20 valves,mcleod RXT clutch, 6.0lr exh manifolds, with a 225int 225exh .581int .581exh 113lsa cam, a-1000 fuel pump 60lb injectors, and a 83mm turbo housing is T-6 1.10 a/r 5íí in and out 2-44mm elc gates oil cooled, air to air inter cooler, ls2 fuel rail, 90mm TB, 90mm mass air, and methanol

    He drives it a lot so itís only going to be at about 6lbs on day to day use so Iím kind of worried about boost creep, but he wants to be around 14-18lbs on the track and late nights and maybe a couple 22+ runs on dyno days.

    If I left anything out just ask
    Thanks, Troy

    Make sure to run some nice head studs other wise you could have the heads lift. Also pin the crank.

    If you're worried about boost creep run dual wastegates or a 50mm Tial. Other than that the other advice given will do you just fine. If he's not running EGT make sure the plug is secured. I'm half out of it at the moment if i think of anymore i'll post back.

    *EDIT* I just read the specs on the turbo....THAT THING IS HUGE! He won't have to worry about 6lbs on the street....if he's just street driving it, he probably won't get out of vacuum.

    It has a split inlet so i'm going to run a 44mm for each bank.

    I no i was almost speachless when i saw it lol

    Correct me if Iím wrong but if it makes 500hp with no boost and 7%hp per psi At 20lbs it should break a thousand just wishful thinking

    its always a guessing game with the HP just depends on the tune...btw what are you using to tune?

    I plan on turboing mine eventually. I'm going to section a rear bin for a hidden rear mount set up in this.

    I have the software ill tune it on the dyno then go the the street and finish the tune there could take a couple times

    I use LS1 edit but i have acess to

    EFI Live - EFI Live, Flashscan, EFI Flashscan
    GM Tech II - Tech II, Tech2, TechII
    HP Tuners - HPT, HP Tuners, HP Tuners EIO
    Tunercat - Tunercat, C.A.T.S.


    Mabe if this goes well that T6 housing is freking huge i think i'm going to move the a/c junk and get rid of the curise control and put in place of the batery "if anyone has a better idea on where to put it i'd love to hear it"

    My camera is messed up but i'll post pic's soon
