69 swb turbo Ls swap

[69restomod]

Bought this gem today it's an 02 2500 hd Silverado 4x4 with the 6.0l and 4l80e got the whole truck for 1500$ with 160,000 miles plan on doing rods and Pistons with ls3 heads a boost cam and a s480 turbo with maybe around 14 pounds of boost. Haven't done an Ls swap yet in our trucks if anybody has any suggestions on motor mounts and motor mount brackets and what accessory drives works in our trucks that would be great oil pan etc. will post as many pics as I can along the way.

I build double walled water cooler stainless steel turbo kits for high end jetskis on the side and I am thinking of doing water cooled housings on my kit to keep down under hood temps let me know what you think!

[69restomod]

This is one of the Borg Warner efr turbo housings I build it would be very similar to this

Got the front clip off driveshafts out and transfer case off pretty close to pulling it out

Duh... I just read the thread title.

I used early classics mounts in mine they worked well but my swap was a 2wd. they make a complete kit with everything for just over $200 that has poly mounts. I used the stock accessories and the stock pan. I have some photos on my one owner short step build

[69restomod]

Sorry guys this is my truck it is going in!

[69restomod]

Here is the current sbc engine setup in the truck now that I will be pulling out here shortly

[boynton]

the mounts I used will work fine for you. I would set the motor back about an inch from the stock v8 holes with those mounts. are you going to run your current transmission?

Ok great I'll look up the early classics setup and I'll check your pictures out cause I would like to use the stock pan and all the accessories air conditioning compressor alternator etc. and I am going to be running the 4l80e that is hooked to the 6.0l I'm gonna have the output shaft changed to the 2wd setup

[69restomod]

So I was just looking at the early classics late mode Ls swap motor mount kit and I was wondering does it have adjustment front and back like a lot of the Ls swap motor plates?

[boynton]

it does not but it worked well for my application. I also used their 4l80 trans mount to keep the pinion angle good

[69restomod]

Ok great well sounds like I got the motor mounts figured out! Did you have to modify the trans tunnel at all to fit the 4l80e in your truck?

[69restomod]

Got the main engine harness disconnected from the fuse panel and got all the power steering lines and cooler off all the heater core lines and Ac lines and trans cooler off, the only thing left is fuel rails and motor mounts, but have to take the pup to dog training and have my girlfriends suprise bday dinner tomorrow night with family and her actual bday dinner Friday night with friends so I will be pulling it out Saturday morning! I am interested in where you guys are mounting the computer? In the cab? On the fender well? And what all is involved in getting the motor running in the truck as far as wiring?

I did. I cut out the low hump and welded in studs for a high hump and then bolted it in just like factory. I use a company called lsx unlimited to do my harness and pc tuning.lsx unlimited is based out of Alvarado and has done well for me in the past they are currently working on another harness for me that I will pick up on Saturday. there is a guy on the board that does it but he never got back to me so I don't know anything about them. if you want to do the harness yourself go to ls1.com they have all the pinouts there.

Ok cool I was kind of thinking I might need to change to a high hump for the 4l80e but wasn't sure, and I'll have to check out lsx unlimited I think I might follow those guys on Instagram, I actually just rewired my whole truck a couple months ago with a harness from haywire so hopefully I won't have to change to much of what I already did lol I'm thinking of running a racepak for my gauge cluster and getting rid of my auto meters, I read over 3 or 4 pages of your 6.0 ls build this morning before look and it looks awesome man!

Thanks. it makes me smile every time I get into it. I ran a relay for my starter because I heard the ls starter solenoid pulls too many amps and can burn up the switch. not sure if it is true but I went with it since a relay is better than replacing my switch.

[69restomod]

No problem man! Ok cool I'll prolly do the same what type of harness did you wire the rest of the truck with? I just rewired my whole truck at the beginning of this year with a harness from haywire and I'm hoping I don't have to re-do much lol I did get the motor and tranny out of the truck last night and I still need to pull the brake pedal assembly and the obd2 port and it should be everything I need off the truck and off to the scrap yard it goes!

[69restomod]

Got the motor and tranny separated and motor on the stand also got the brake pedal assembly and brake switch and harness pulled out of the donor truck!

[69restomod]

4l80 e will be headed to the trans shop this week!
