Poll: 76mm Turbo or Heads/Intake?

[dville_gt]

me, john (the green mile), Nathan Hale (the white 65 ford truck, TJ (nathans cousin with the green 36), August (60 somthing lincoln) another guy with a 65 chevy truck

we all have the exact same turbo some of us have LQ4 some have LQ9 and one has a LY6 (i think that is right) (Sam would know for sure)

all mpt76 q trim .96ar?

how much injector did you need?

[2165 Turbo Rail]

yup all have the MPT76 (not going to lie.. don't remember if its q trim)

we all use 60lbs injectors and either Walbro 255 or Bosch 044 with corvette filter/regulator

Colling and BJ have 5.3 N/A

point taken. after looking at a t76 map it looks like it really is ideal for this motor.

question now is if there is any way to aquire one for less then 640.

also, is the .96 what all the 6 liter guys are running vs. the 1.0ar exhaust housing?

Try the Magnum 76. You can get one local from Vyron. .96 is what Chris and all of the other guys have run.

Yes all are mpt76 q trim.
You only need a 60lb injector. Buy a NEW set of the SD 60's. You will have to upgrade to a two bar sd OS and use the 12580698 GM two bar map.
Have you given much thought to changing the cam?

was planning to return to the stock lq9 cam and leave the good springs and hardware on the 317's

since i am already running the ls7 injectors can i not just have FIC convert them to 60, 80, or 93lb for like $200?

[dville_gt]

$200 and he'll make the ls3/ls7's 72lbs @ 3bar

Tuning a modified injector is no different than any other, the only thing changed is the discharge plate, the injector orfice nor valve is touched. All Bosch LS style injectors are the same basic injector, the discharge plate and color is the only difference. So, we copy those plates and turn yours into the size required.

why not do the 3 bar sd? does it cost more credits then the 2?

The reason I suggested the SD60's is the actual injector data is out there which makes tuning it very nice.
The stock lq9 cam is the same as a stock ls1 cam. You should try the ls6-ls2 cam insted. Its worth 20rwhp over the lq9 cam and can be found for $50-$75.Or another option is the LS9 cam. You can buy it new for $120.

Throw some fofisixes in that bitch.


Or a B headed mod motor if you really want to go fast.


Lol

good to know, are any of these cams on a smaller base circle? i went with 7.425" tsp pushrods that i assume won't work with stock cams (i believe stock is 7.375").

i have a buddy who i think has a ls6 cam that he'd sell me cheap. if not do you have a part number for the ls9 (is it worth any extra hp?)

also, how much harder is tuning going to be vs. what i have currently? i assume it is the same game, logging afr error and modifying the ve table accordingly (obviously with a more aggress PE rate and less timing)?

[Sam88gta1]

Because you have no reason to run a 3 bar sd. This goes back to wanting the s400 because its bigger. No reason to buy something you are not going to use.

damn you and bringing sound logic into my thread guess i figured the only difference was additional cells in the VE table and if it cost the same amount of credits why not. i was just wondering if the resolution on the 3 bar is less or something. point taken regardless.

got a b headed black 97 cobra sitting the garage that hasn't moved in about a month if ANYTHING happened to that motor you probably already have a real good idea what would be replacing it!

All of the ls based motors use the same length pr (7.325) with the exception of the ls7.
The ls9 is part number 12605527. I would say the ls9 is worth 15-20 hp more.

Two Bar sd is much like what you have done in the past. When it comes time to tune it shoot me an email and ill help you with that.
