a hummer. After doing some search on the forums, ebay, local sale forums; i found this 6.0L. Will it fit the 2003 suburban, i am planning on taking a drive down to S.A, TX and have Nelson Performance do the work for me. If this fits what do you guys recommend i change on the engine as far as performance goes or needing it to run. Could you guys give me some pointers:dancenana:
Thank you,
Miza
What are your goals?
Keep truck for another 10+ yrs. As far as power goes, I would like to put another couple 100 horses. Truck will be mainly used for family trips and pictures. : P
Want to also install a nice exhaust system to it.
Im just a 21yr old that has had this truck since graduating in 05 and working in UPS and now... jeje im doing good. I really dont know what else is needed. My old folks lost hopes of returning to mexico in december because of the truck issues. The engine is knocking and will not respond to the pedal, i want to really keep the truck in the family since its been extremely loyal to us. She is about 8/10 from the outside and 9/10 in the inside.
Long tube headers with ORY, nice exhaust, Camshaft of the right size, and a tune should give you almost an extra 100hp. You WILL have to build your current trans to handle this power. Been there and in the process of doing that.
Although if you want to use it for trips and such, I wouldnt go to radical on the hp...IMO
Was kind of wanting to stay away from messing with the trans. I will stick with engine and nice exhaust system, also looking to buy the ltz silverado wheels, those wheels are mouth drooling on the surburban
Theres no way to get around it. I dont mean to be a party pooper, but even 6.0 with a tune will need a beefed up trans. A stock 4L60E trans cant hold that much power/weight for long.
No its cool thats what i need guidance. What will be needed for the transmission?
Are you going to get the trans out of the hummer? I beleive they are a 4L80E.
Which would handle the power better than even a built 4L60E. Even though the 4L80E will be a hassle to put in, it will be less of a hassle in the long run.
Well if i can find one then yes.
The 4L80E will be the better option of the two for holding power. I would find a good trans guy in your area and tell him what you plan to do. He could then beef up your trans based on that.
I myself will probably end up getting a stage III from FLT for about $1,600.

im looking at 5000 at minimal with engine,trans, and work.
The engine thats now on the suburban, can it be fixed?
What would i need to get this 5.3 its life back or should i just swap out. Trying to weigh my options here
How many miles is on it?
150,000
Without knowing what is wrong with your current motor I would reccomend this. Although on average, these motors an go much longer.
If money is an issue I would just get a salvaged 5.3 with 50,000 miles or less and swap that in. These can be had for less than $1,000
If you want more power swap in a salvaged 6.0 LQ4. These can be had for $1,400 and less in my area. But it really comes down to money. If you want more power you are going to spend more money on motor mods, and supporting mods like trans work.
And just to let you know, if you plan on doing mods on a 5.3 you will still need to beef up that tranny, especially with 150,000 miles. It might be cheaper to get that level 3 from FLT.
:sissies:
Where exactly in your area can you get the engine? I live in Arlington,Tx
Got mine from Denton County Auto Salvage. I was in a race with James Wood for it though...
Google DFW auto salvage and a few will pop up. Give them a call.
We use Denton County Auto Salvage here for used assemblies...usually for insurance jobs.
I would check LKQ too. I paid $255 for my 5.3 complete, no brackets/accessories or wiring. 110k from a 2002 tahoe, iron block/alum heads, 90 day warranty. put it into the JImmy for testing, 50psi oil pressure warm at idle. sounds good.
hummers also came with a 4l65e which is a beefier verson of your current transmission,, also a direct swap no tuning needed
Ok i think i will start the project mid september. Buy will start maybe this coming month
If you go from a 5.3 to a 6.0 you will need your PCM tuned...
looking to get flt stage 3 tranny
lq4 6.0
anything else
going to get nelsons peformance tuner
thats what I am running, minus the trans for now. Good power, but if you want more hp like at the beginning cam it.:burnrubb:
will this fit "This is a 6.0 litre engine with L92 heads from the factory out of a 2008 chevy 2500hd with 28,000 miles. This motor comes stock with 353hp and i s capable of around 500 with a cam, intake and headers"
