6.0 T-76 turbo setup
6.0 T-76 turbo setup How much power will my combo make? My set up is in the works right now. I have a 02 LQ4 6.0 (stock bottom end), 02 ZO6 cam, LS6 intake, 90mm TB, 6.0 manifolds, Precision Ind. T-76 turbo .96 A/R, front mount setup. I've upgraded to Katech rod bolts. I'll be running a built 4L60E, Vigilante converter, and a 9 inch w/high 3'ish gear. Does anyone see any problems with my setup or places where I need to upgrade? This is my first turbo build. I'd like to see close to 700 rwhp. That's close to my goal anyway. All info and input is appreciated.
It will make what you feel comfortable with. On pump I would stay under 550whp to keep from breaking the pistons. With good fuel I have broken 700whp on a hand full of stockers and had them last for a long time. The turbo will get you there though.
That's a good question extremetoy. I'll also being running a meth injection kit. I know that will help. Would it be possible to run pump gas, spray the meth kit, and make close ta 700rwhp? Or I could mix pump & race and spray the meth kit.
I have not broke one from hp yet myself, all though looking at them I would not trust them to hold on for any more then what the pistons can. I imagine one little bit of detonation would kill both the rods and the pistons with more then 700whp.

Verdad Gallardo Yes, still at your own risk, I have done it with a handful of engines w/o a problem. Remember it could be scary to drive over your rotating assembly with some good speed.
LOL Yea, that wouldn't be good. I just noticed your post under ur banner for the 825whp LQ9. That's awesome. Is that on race gas only? I thought about forged pistons & a good set of rods. I just think it's kool ta use the stock short block and make gobs of power.
Stock48 over on performancetrucks.net found the limit of stock internals on the LQ4 when tuned properly. His was a stockish, (cam and hand ported 317 heads) long block and a T76 turbo with a .68 A/R housing. Ran in the 10.50's at 127-129 I believe in a 5000lbs, reg cab 4x4 TRUCK, at 5000ft elevation! Pushed the motor to the limit and finely failed the rods, not the rod bolts, not the pistion, but the rods! Every rod in the motor was bent, S-shaped or broken when it failed. Good old number 7 piston was still intacked and showed no sign of detonation. I saw the carnage with my own 2 eyes. He was running a mix of 75% 91 and 25% E85 and no meth.

any ideal on what kind of power it was putting down?
Here is some of his post over on PT.net, I miss spoke, truck weight was around 4900 and his mph was around the 124-125 range with a 10.58e.t. Oh, and he did end up putting meth on it.

wow, that about answers all my questions.
I'm planning on a lq4,z06 cam,stock 317's with some valvetrain work, masterpower gt42. looking for @600 on 50/50 e85/91 meth. should be no problem.
if it last a season I'll be happy. (season is like 9 months in AZ)

everyone should just forge their bottom end or limit their boost to 10lbs. I understand money is the issue, but if your gonna blow the stock bottom end you gotta have money to replace it unless you plan on stripping vehicle of turbo kit and selling without motor?
thanks for the links. Looks like he even pushed it far for pump gas with a little e85. Somewhere some one said the 5.3 is stronger then a 6.0 instock form. Is their any truth in this statement?
As cheap as 5.3s are I might just try to get a deal on two so i have a spare and after the first one breaks I will know the limit. After reading some of Parishs post and others timing seems to play a big role in making them live.

buy the time the year or so is up I'll have enough for another jy motor if I need it. it's easy to put away 25-30 a week for a year so I can enjoy my car, the way I want to.
but thats just me, I'm young and barley clear 50k. :shrug:
