Officially Swapping in a 6.0/2wd 4L80e into my 99 OBS Escahoe - GET DA WATER

Here is a link to my original build thread where it all started! I like to thank ALL the members over there...they got me started and I am here to finish it!

I was just about to install A Pro-Charger with a few bolt-ons and the spyder unit went. I just re-did the heads and installed a new unit about 30k. I couldn't find a Marine Intake Manifold either. Guys over GM Performance persuaded me to swap in a LS motor. I got lucky and came home with 6.0L/2wd 4L80e, complete harness and PCM out of a 00 Chevy 2500 Series HD with 111k on it.

Finally got it home for the tear down & Prepped for paint

Now for some REAL TALK, don't ask me why but for some gawd awful reason I thought I would have this thing installed for 5k with some FI. I am past that at this point and as of right now there is NO F/I being swapped in, it will come later as well as a stall. I promise. She is set-up for boost with LS9 Cam...once I get F/I on her then a custom cam will be on order. Here is my parts list...I included every part number and place where I got it from and why. I have seen a lot of build threads on a few forums...NO PART numbers and no rhyme or reason why they got the part.

I choose to get the ARP Crank Pulley b/c I am keeping this set-up for a very long time! I do not want to buy a new pulley every time I dissemble the motor (costly).

http://i270.photobucket.com/albums/j...0/IMAG0740.jpg

BUT...

I was in the midst of purchasing injector's 8.1 Marines...The seller informed me that the 99 OBS has a return style fuel system and L92 Truck intake is set-up for Returnless...I need to convert as well as make custom TB cable bracket since L92 is orignally a DBW set-up. I was at work and he kinda pressured me into buying 8.1 Marine Injectors, modified fuel rails for the conversion and the TB Cable bracket. Honestly I paid 200 for everything...says it is possible for one of the injectors needs to be bleed. The only reason why I got the fuel rails is b/c of basically the price he gave them to me at. Price of AN fitting...my time and sweating my nuts off cutting into the fuel rails and having the AN fittings...not a bad deal. Just don't like being husselled.

Is he telling the truth...if so what else needs to be done as far as fuel system wise to get the conversion going? Also said I will NOT need adapters for the injectors...snap right into my harness.
Do I need a Aeromotive FPR now...do I need a ad a inline warlboro with SS Lines and fittings?

Keep your fingers crossed and pray a lot that you dont get those rear two cylinders too hot and loose a ringland. A lot of people have seen cylinder temps get too high in the rear cylinders because of poor coolant circulation and the older style crossover which helps to bring the coolant to the rear as well has been know to help fight that.

F-*-C-K

I couldn't find a brand a new one...know where I can get one?

Under what conditions where the cylinder's getting hot? I don't plan on hot lapping the truck...just a nice little DD...my HP goals are b/w 550-600 when it is all said and done. I am extremely interested in entering the Sandhills Open Road Race in Arnold, Nebraska. I want to compete in the 80mph trap. http://www.arnoldne.org/pages/sorc

HELP ME get it done! :)

I am still stuck on the fuel issue but none the less project MUST move on.

Spent the last 2 days finally stripping, prepping, & painting the transmission.
It is a 00 2wd 4L80e...Only mods the Transmission getting is a MagHytec Deep Pan, Transgo HD 2 Shift Kit, Lokar Dip Stick, and lines hooked up to the biggest transmission cooler I can find.

I choose Purple b/c same color as the amazing ATS Diesel Transmission plus it is the wifey's favorite color. I tell her I painted it b.c its your favorite color and your so supporting of the build...NOT...the guys and everyone else...Just a lil mimick of ATS.

I could not find Purple gloss anywhere! I went onto amazon, well there was three pack, primer, paint and clear coat! Awww, I never primed nor cleared my engine block. It is too late by now. So I ordered the three pack and Compare which holds up longer...Motor or Tranny paint?

Here are some pics...

Cleaning and Stipping...Used Purple Power, then hit it with wire wheel, then wiped down and blown dry

Just got my oil cooler lines in.

Tonight going to order my Mag Hytec Deep Pan, Transgo HD2 Shift kit

I was originally going with Schoenfield Conversion Headers...but Since I am 2wd I have a few more options...like Actually NBS headers....

What you guys think? I WANT THE TRUEST FORM OF LONG TUBES

Amazin ATS LOL nice one.

I went to order my schoenfeld headers...I can only find for 2wd trucks.


What is out there for 4wd trucks. I am swapping in a 2wd 80e...but I am still retaining my torsion bars. I do not have a transfer case & front drive shaft.

Ended up ordering the Painted Headers off of Amazon like a $50 difference plus free shipping. Then they got me with sales tax which I never paid before. Still came out $15-20 cheaper then anyplace else via Ebay, Summit, & Jegs.

I got painted as I didn't trust the Armor Coat Ceramic Coating. I <3 Black!
I will start test fitting the motor and trans. Once that Is complete and header's have been massaged into place I will send them out to get Ceramic Coated in Black!

Thanks!

My build has come to a halt due to the fact of cold weather. There for I can't clean up, prep and paint the engine bay.

I think I have everything in order...for the swap ( think) EXCEPT FOR FUEL

I want to tackle the wiring harness b/c IMO this will take me longest.

Where is the best HOW-TO-Step by step process. I am an amateur when it comes to wiring and reading diagrams. (Running lights and gauges is my specialty...anything after that I am a fish out of water).

There is a sticky on the forums for wiring, is that what you guys have used?

Little bit confused your using factory 411 computer and harness, but buying all these LS2 sensors I'm assuming all these sensors plug up?

I am sorry for the confusion.

I have a 99 OBS Chevy OBS 4x4
I also have a 411 PCM that needs to be installed. Install is easy (just time consuming) need to take each wire and just re-pin it.

What is going in...
6.0, 2wd 4L80e, E-Fans from 06 Sierra
I have the Harness and PCM out of the 00 Chevy HD in which the motor and trans came out of

sick build! i wish i would have seen it sooner i went with lpp headers all stainless steel including y-pipe for 450 to the door best quality ive ever seen for the price!

At this point it is just a bunch og big what IFS...my plan is to run pipes back to Dynomax crossover X muffler (built in X Pipe) then exit out the side before the rear tire.

I really want boost, just waiting for the right opportunity to do so.

nice truck

Where are you located in ny?I am in warwick ny near Middletown.I would like to checkout your truck.

I am located in Long Island, NY. Seems a little far but you want to take the trip let's drink some beers & spit on some hookers.

Sad just drove up to Curfo on Wednesday. Def swing thru and spend the night no problem.

Originally I wasn't going to purchase a underdrive pulley. Just didn't see the real $ to power. But I scored a JEGS 25% truck underdrive pulley on ls1 for $160 with an ARP bolt. I don't need the ARP bolt...if YOU DO LMK.

Just wishing for warmer weather.

For you guys that are lowered...are you guys running into Oil Pan clearence issues using the truck oil pan?

The truck oil pan sits about 2 inches lower than the front crossmember on a 1992 2wd pickup.I bought my truck already lowered so i am not sure how much it is lowered but i have no problems.The truck is c notched in the back if that helps.

Thanks for the response. My truck is 4wd but going 2wd witht he 80e. I am running 22's with staggered tire size. But my rear is 305/40/22. Just have shackles in the rear. Once I get this thing running I have Hangers, C-Notch and Firestone Air Bags waiting to be installed. I can not go any lower in the front or else I risk bottoming out unless I do some trimming which I refuse to do. I do not want any debris getting in my engine bay.

It is getting warmer out...start the final stages of prepping before the actual swap.

For those who have swapped...Did you guys run the wires to the 411 or hacked up LS Harness? Keep in mind I am looking to retain All the goodies...A/C, Cruise Control and ABS

Thats where I am at right now. Cant decide on which way to go. I have all the info to go either way but cant make up my mind.

I used the original harness supplied with the 6.0. Modified it for my truck. I retained the A/C and cruise control. I'm sure your vehicle will be different with all it's accessories and difference in year from mine. It took some work but I felt it was worth it. It gave me a better understanding of the entire electrical system.

Ok, So finally after almost a year Lextech is finally sending me a pre-programmed 411 as well as A/C Bracket kit. Here is a link to all the info on it (http://www.ls1truck.com/forums/lsx-t...acket-kit.html) I wish Lextech was closer so he can do a live tune, but his pre-tuned 411 will help get the truck started and hopefully run smooth enough for me to take it to ForceFedEngineering (http://www.fferacing.com) to get it Dyno Tuned.

I needed my gear ratio and I was not sure so I finally looked up my RPO code and this website was the besthttp://<a href="http://LonestarThund...hunder.com</a>

So I have 3.42's from the factory. Also needed to know exactly what injectors I am using for the tables and 8.1 Marine Injectors by Delphi Model#17113739.

I picked up the injector's used also the seller got me (I think) in a vulnerable spot) Said he had modified fuel rails (welded AN fitting) help with the swap so for few extra bucks I got them as well. Figure just put less stress on my buddy who is helping me with the swap. I am stuck in a rut with the swap as it comes to getting the Fuel System squared away. Not sure if my Tahoe is return or returnless and same is for my 6.0.

What do I need to order or fabricate to help get fuel to the motor?

Here are the links to the fuel rail

http://i270.photobucket.com/albums/j...ps55843a06.jpg
http://i270.photobucket.com/albums/j...psa3d3a222.jpg

I am personally leaning towards using the 411 with the additional wires for simplicity. If I can't get the wires to look nice and neat then I will go the other route. For now my heart is in re-using the stock harness and making it nice and neat!

How are you guys getting fuel to the LS motor? Am I on the right path with the AN Fitting welded to the rail...need to use a stock one. Some people run a corvette fuel filter and some do not.

I have a 99 OBS Tahoe...what do I need to get this thing fueled before my fiancee finds out I have money set aside and she puts it towards the wedding.

The Corvette filter is for the single fed line to the pre obdII motors. If I remember correctly. Yours should have 2 lines. A feed and return. from what I gather there are fittings that attach to the furl rail lines and will snap into the the lines in the firewall. Maybe with some fuel injection rubber lines for the flexibility.

This is from a thread on here.....

THANKS FOR YOUR RESPONSE...I saw that as well...but on MYZTERRAY build thread which is a 96 ( I am up to page 21 he has ordered parts for the vette filter and his truck is OBD 2 as well) I can not Copy and Paste since I am at work on the 11th page of thread he talks about getting the parts.

It depends on what type of fuel rail you have. do you have a return type or returnless type? i wish i took pics the other day of my finished settup but i forgot so i cant post any. but just look at your rail. if you have two lines headed toward the back, one bigger than the other than you have a return type. if you only have one, its returnless. the guy hacked yours up so you may not have what im talking about anymore. how many an fittings do you have? that should tell you.

anyway, most people convert to an so you can skip a couple parts. if you have returnless, thats when youll need the corvette filter. it has an IN and RETURN on one side and the other goes to the fuel rail. here is a diagram that i found with the required parts/numbers/and shows how they are connected. you will probably not use some of this stuff depending on hows yours is set up. i bought all these parts and it worked like a charm.

Thanks...Well I have two sets of fuel rails...one that is currently on the motor out 00 Chevy 2500 HD and the modified ones...

It might be hard to tell about the HD one de to the pics I took of them...motor assembled. I will look at the "modified" fuel rails later tonight. Chime in and post better pics. The "modified" fuel rail has one AN fitting welded to one rail.

I used high pressure fuel injection hose and the appropriate clamps. I also used a double flare tool to put a bulge on the fuel lines so the hose wouldn't slip off. I simply cut off the fittings and bulged the ends of the lines. I'm also running the standard fuel filter. My truck originally had TBI but after checking part numbers, the filters are the same from the TBI to Vortec injected small blocks.

If you have the original fuel pump for the Vortec injected traditional small block, that is able to supply the needed pressure to get the LS engine up and running.

aha! found a pic i took of the feed and return lines when i first got my motor. the upper is the feed and the lower is the return. not the greatest pic but thought i might help to have something to compare to
