'96 silverado lq4 I am swapping an 6.0 lq4 into a '96 chevy extended cab, i want to say curb weight is approx. 4100#. I am also going to put a turbo on it, goal is for somewhere in the 550rwhp neighborhood. here is the plan, and i am looking for input.
bone stock lq4, except for some pac 1218 springs
truck intake dbw throttle body
4l80e with transgo hd2 and stock converter
trick turbo manifold
siemens deka 60# injectors
walbro400 in tank
ebay intercooler (probably 30x12x3)
on3 78/75 turbo
ive been doing a bunch of internet research and feel like this combo should meet my goals, but there is a ton of white noise out there and figured i could directly ask for input. One of my big concerns is running the on3 78/75 with a stock 4l80e converter. Will it take all day to spool? picking up an aftermarket converter would be ideal, but would be cutting it awfully close on the budget. should i go with the smaller 76mm?

Sounds like a solid combo. You might as well go up to 80# deka injectors since they are almost the same price.
Stick with the 7875, the 76mm has a smaller turbine and between the 6.0 and your weight, it will likely choke up early.
The stock converter will work but it'll leave you wanting more. Revmax sells 80e single disk converters for the 80e for 500 bucks.

subscribed for this! very interested to see how this goes as i have been wanting to do a similar setup in my 96, but cant decide between a blower or a tubo on a 6.0. im assuming yours is 2wd?

Dont forget Circle-d makes a $500 278mm non billet converter. I ran one in my last truck which probably made 500 wheel. Oh and I'm completely satisfied wit the on3 78/75.

I guess I'll be the odd man out and say I liked my stock 4l80e converter. It was from a gas truck, not the diesel version. It spooled my 7675 well enough. Don't get me wrong, I like my 265mm FTI better, but if money is a concern, the stock converter isn't bad. I had it for several years at the 700rwhp level.
My DEKA 80's idled like stock. No reason not to go with them over the 60's.
550hp...yeah I remember saying something like that too when I started. It's just so easy to make more.

I've pretty much decided to just use the stock converter. i will just save up and get a nice billet converter after i've got all the bugs worked out(and not risk running out of cash just getting it running).I'm fully aware of how turbo builds can get away from you. my last turbo project was an '87 gn that was originally going to be "mostly stock." 6 months later it was an 11 second 6cyl daily driver...How else will you find the weak link unless you turn the boost up?
we are about replace my brothers 5.3 that lost oil pressure, and that would make a nice core to start a more turbo specific build. The only reason i got the lq4 was because i happened across a good deal.
I will probably get the 80'so i dont have to buy a second set of injectors when i turn it up. it just seems like there is a lot of back and forth with people saying they work fine and people who cant get them to idle right. I did go ahead and pick up Greg banish's book. we will see if that helps me make a more informed decision. I plan on doing my own tuning so i may end up getting the dvd's with the injector data that everyone seems to say is the way to go.
It should be a little bit of a sleeper, its not a whole lot to look at right now. started out as a 260k mile work truck that i gave $400 for. it isnt particularly beat up, but it isnt cherry either. it looks like a work truck... though i do live about 10 minutes from dbrods shop; and for a town with a population of around 16k, there sure does seem to be a lot of turbo lsx powered cars around. i think the secret is out.
i will post up some pictures once i get the drivetrain installed and the truck off the rack.

engine is in and i set the turbo/manifold on to see how everything lined up. looks like i will need to do something with the oil fill cap since it is EXTREMELY close to the turbine housing.
anyone in the austin area have a valve spring tool they want to lend to a guy in need?

no, i am using the trick performance log style cast manifolds.
I'm not sure exactly how much room there is. I am using the dirty dingo mounts that have quite a bit of adjustment. I will know for sure in a couple days after i get the 4l80e mounted. I am going to move the engine back as much as possible.

An A2A intercooler? If so, it's going to be heated up drastically by the radiator. Or do you have some creative duct work in mind?
No, it's A2W, we've used the same intercooler on a standing mile 5th gen. Camaro in the same location with amazing results, dropped IAT's drastically with room temp. water.
